Abstract:

The procedure of crestal maxillary sinus floor elevation presents a great challenge to the field of implant dentistry. Due to the limited visualization in this procedure, the effectiveness of detaching sinus mucosa could not be assessed in real time. We recently developed an ex vivo goat sinus model by cutting the goat residual skulls along four lines determined from computerized tomography (CT) scans, extracting the maxillary premolar or molar teeth, and preparing implant socket in the maxilla. The generated ex vivo goat sinus models exposed the maxilla and the whole maxillary sinus mucosa, thus enabling real-time observation of detaching maxillary sinus mucosa via directly visualizing the working situation of sinus lift tool in the models and directly measuring the length of detached mucosa and space volume generated under the elevated sinus mucosa. One commercially available umbrella-shaped sinus lift curette was used to detach the maxillary sinus mucosa to evaluate the effectiveness of the ex vivo goat sinus models. The results showed that this curette could detach the sinus mucosa 3.75 mm in length in the mesiodistal direction and 2.81 mm in the buccal-palatal direction. Moreover, a space volume of 52.7 μl could be created under the elevated sinus mucosa in the goat ex vivo models. All the experimental results suggested that this ex vivo goat sinus model might be useful in the evaluation of improved or newly designed sinus lift tools for elevating the maxillary sinus mucosa via the crestal approach.

Abstract:

Maxillary sinus foreign bodies are interrelated with different types of treatment of pathologies of teeth of the maxilla. Foreign bodies can be presented by pins, sillers, impression materials, teeth, dental implants etc. Features of anatomical development of maxilla, degree of pneumatization of it and many other factors promote hit of the foreign body to the maxillary sinus. Detection of the foreign body in the maxillary sinus during the operation sometimes can become a serious technical difficulty and needs a surgeon to be a man of experience. Important part of success of the surgery is selection of access to the maxillary sinus based on the 3D computed tomography data. We represent a clinical case of treatment the patient with the maxillary sinus foreign body after two non-resultative surgeries. After the implantation of dental implant, patient appealed for medical treatment, complaining on the discomfort, passing pain at the right buccal region and secrete from the right part of nose. We know from the anamnesis, that the patient was operated through the anterior maxillary wall under the general anesthesia for two times. The foreign body was removed only during the third surgery, that was done under the local anesthesia under the control of the rigid endoscopes. The patient was conversed to the out-patient treatment at the day of the surgery. The efficacy of the endoscopic endonasal approach to the maxillary sinus through the inferior nasal meatus in case of maxillary sinus foreign body was approved.

Abstract:

ABSTRACT Introduction: Sinus lift surgery allows sufficient volume of bone to be created in the posterior part of the maxilla. The aim of this study was to investigate the changes in maxillary sinus volume after a sinus lift and the rate of increase in ridge height at the site of the graft. Methods: Eleven patients were chosen for sinus lift from among those who were referred to the radiology department for implant placement in the posterior region of the maxilla and whose bone height at the posterior of the maxilla was less than 4 mm on the cone-beam computed tomography (CBCT) image. The sinus volume was measured after importing the CBCT file in DICOM format into Mimics software. After determining the sinus volume, the patients underwent sinus lift surgery, and the amount of material used during the surgery was measured. After the time required to repair the area, the CBCT image was taken again. Then, the changes in the volume of the maxillary sinus and the increase in the height of the maxillary ridge at the surgical site were calculated. Then, the second stage of the surgery was performed to place the implant at the implant site. Results: For an average of 1.40 cm3 of material, the rate of increase in ridge height was 10.52 mm, and the average change in sinus volume was 1.19 cm3. Conclusions: CBCT images and Mimics software have many applications in examining and predicting parameters before and after sinus lift surgery.

Abstract:

Introduction. Large maxillary cysts occasionally expand into the maxilla and erode the maxillary sinus and nasal cavity. The Caldwell-Luc procedure is the recommended treatment for large maxillary sinus cysts. However, it is hard to preserve the nasal space in the case of large maxillary sinus cysts that penetrate into the nasal cavity.Methods. A 22-year-old man who had large maxillary sinus cysts was referred to our department for a surgical treatment. After removing the cyst from the maxillary sinus using the Caldwell-Luc procedure, we used nasal airway and balloon catheter devices to preserve the space of the inferior nasal meatus and maxillary sinus. These devices were removed 10 days postoperatively. Insertion and removal of both devices were simple and painless.Findings. The nasal airway and balloon catheter devices were useful for performing maxillary sinus surgery to remove large cysts. Our method was satisfactorily safe and was an effective minimally invasive treatment that preserved the space of the inferior nasal meatus and maxillary sinus.

Abstract:

In the present retrospective study, we aimed to assess the replicability and reproducibility of a novel digital measurement technique for analyzing the volumes of the left and right maxillary sinuses and the nasal and maxillary sinus airway complex after a sinus lift procedure using the lateral window approach, to provide an accurate measurement technique for easily applying in clinical practice and to allow pre-operative assessment of maxillary sinus lift surgery, avoiding complications and making surgery more predictable. Material and Methods: Thirty patients with partially edentulous posterior maxilla were selected and submitted to bilateral sinus lift using the lateral window approach technique, with grafting materials selected and submitted to cone beam computed tomography (CBCT) scans, both pre- and postoperatively. Then, datasets were uploaded to therapeutic digital planning software to measure the volume of the right and left maxillary sinuses and the nasal and maxillary sinus airway complex. Gage R&R statistical analysis was performed to assess the replicability and reproducibility of the digital measurement technique. Results: The variability attributable to the novel digital measurement technique was 3.4% for replicability and 3.4% for reproducibility of the total variability of the samples. Conclusion: The novel digital method proposed is a replicable and reproducible technique for analyzing the volume of the right and left maxillary sinuses and the nasal and maxillary sinus airway complex after a sinus lift using the lateral window approach technique, allowing an accurate pre-operative assessment of maxillary sinus lift surgery, avoiding complications and making surgery more predictable.

Abstract:

This study aimed to determine the incidence of maxillary sinus pathology in patients with a midfacial fracture who underwent osteosynthesis surgery and evaluate the associated risk factors. We conducted a retrospective case-control analysis of patients with midfacial fractures involving a maxillary sinus wall who were treated with open reduction and internal fixation (ORIF) between January 2015 and December 2020. Fracture reduction, the number of screws implanted in the maxillary sinus, and the number of screws penetrating the maxillary sinus, etc., were examined as potential risk factors. Maxillary sinus pathology on postoperative CT was considered the primary outcome for case-control analysis. Binary logistic regression was used to identify variables associated with postoperative maxillary sinus pathology. Thereafter, propensity score matching (PSM) was used to extract confounding factors. A total of 262 patients (totaling 372 maxillary sinuses) were included for analysis. PSM yielded 178, 246, and 70 matched sinuses, respectively, depending on the potential risk factors. Postoperative maxillary sinus pathology was visualized in 218 of the 372 maxillary sinuses (58.60%). The risk factors for postoperative maxillary sinus pathology included the number of screws penetrating the maxillary sinus (odds ratio (OR), 1.124; p = 0.007), an imperfect maxillary sinus wall fracture reduction (OR, 2.901; p = 0.021), and the number of sinus walls involved (OR, 1.383; p = 0.011). After PSM, postoperative maxillary sinus pathology was still more prevalent in sinuses with multiple maxillary sinus wall fractures (64.04% vs. 48.31%, p = 0.034), sinuses with more screws penetrating the maxillary sinus (64.23% vs. 50.41%, p = 0.028), and sinuses with an imperfect reduction (80% vs. 51.43%, p = 0.012). In conclusion, maxillary sinus pathology is common after the ORIF of midfacial fractures. Patients with a fracture of multiple maxillary sinus walls require a close follow-up. Screw penetration of the maxillary sinus should be avoided to prevent maxillary sinus pathology after a midfacial fracture ORIF.

Abstract:

The insertion of dental implants in atrophy maxilla is a complicated issue because no bone support due to expansionof maxillary sinus and atrophy of maxillary ridge alveolar. Surgery by sinus lifting with autogenous bonetransplantation has been proven to be an acceptable treatment to get bone support. The lateral window techniqueand transalveolar osteotomy sinus lifting are the methods to correct the height of inadequate bone in the posteriorarea of maxilla for preparation of implan dental insertion. Technique of transalveolar osteotomy sinus lifting isnoninvasive compared to lateral window sinus lifting technique.

Abstract:

Objective. To explore and analyze the application effect of external and internal elevation of the maxillary sinus in implant restoration of the posterior maxilla. Methods. A total of 84 patients undergoing implant restoration of the posterior maxilla in the hospital were enrolled between January 2019 and March 2021. According to the random number table method, they were divided into the observation group (n = 42) and the control group (n = 42). The control group underwent external elevation of the maxillary sinus, while the observation group underwent internal elevation of the maxillary sinus. At 6 h, 12 h, and 24 h after surgery, the pain degree between the two groups was compared. All were followed up at 6 months after surgery. The osseointegration (bone resorption around implants, elevation height of maxillary sinus floor, average healing time) and soft tissues (bleeding index, plaque index, probing depth) in both groups were observed. The occurrence of postoperative complications was recorded. Results. At 6 h, 12 h, and 24 h after surgery, VAS scores in the observation group were significantly lower than those in the control group ( P < 0.05 ). At 6 months after surgery, bone resorption and elevation height of the maxillary sinus floor in the observation group were significantly higher than those i.0.0n the control group, and the average healing time was significantly shorter than that in the control group ( P < 0.05 ). The bleeding index, plaque index, and probing depth in the observation group were significantly lower than those in the control group ( P < 0.05 ). There was no significant difference in the incidence of postoperative complications between the observation group and the control group (9.52% vs. 19.05%) ( P > 0.05 ). Conclusion. The application effect of internal elevation of the maxillary sinus is good in implant restoration of the posterior maxilla, which can relieve pain and swelling and improve implant effect.

Abstract:

The oroantral communication is considered one of the most frequent complications in oral surgery, especially in extractions of posterior teeth in the maxilla, treatment of cystic lesions, neoplasms, osteomyelitis and trauma in the region of the maxillary sinus, forming fistulas. However, ectopic third molar and lesions such as odontomas are rarely found simultaneously in the maxillary sinus. This report shows a successful treatment performed in a specific case of oroantral communication, associated to an underdiagnosed complex odontoma and an impacted ectopic third molar into the maxillary sinus and discuss the requirement of intervention. The treatment strategy involved clinical and surgical management through the oroantral communication, avoiding additional bone access to the maxillary sinus. This proposal presented a satisfactory result, and at six months after surgery, the patient has an excellent evolution, proving to be a successful strategy.

AbstractObjectives:Endoscopic sinus surgery has been widely performed to treat nose and paranasal diseases. However, it is difficult to manipulate anterior wall lesions of the maxillary sinus using conventional surgical instruments. This paper presents a method of performing endoscopic surgery for anterior wall lesions of the maxillary sinus, using a 135° reflective CO2 laser.Method:A CO2 laser with a 135° reflective tip on the pipe-guide handpiece and a CO2 laser angulated to the same degree were used. The pipe-guide handpiece with reflective tip was inserted into the nasal cavity and the base of the maxillary sinus anterior wall lesion was vaporised and removed via an enlarged natural ostium. During the procedure, the maxillary antrum was visualised with a 70° endoscope. Ten cases of maxillary sinus anterior wall lesion underwent this surgical procedure.Results:In all cases, the base of the maxillary sinus anterior wall lesion was removed completely and recurrence avoided.Conclusion:This method is a reliable procedure enabling endoscopic sinus surgery for anterior wall lesions of the maxillary sinus.

Abstract:

Endoscopic sinus surgery is commonly performed to treat odontogenic maxillary sinusitis. However, recurrence and natural ostium reclosure often occur due to the inadequate patency of the excretory route. Furthermore, classical maxillary sinus radical surgery is still performed for odontogenic maxillary sinusitis even though it can cause postoperative maxillary sinus deformation, loss of function, and a postoperative maxillary cyst. A management that addresses these issues has not yet been identified. This study reported a conservative maxillary sinus management, wherein a nasoantral window is prepared and the thickened maxillary sinus mucosa is preserved, using the Caldwell–Luc approach. This study presents a case of severe odontogenic maxillary sinusitis that spread to the frontal sinus. This novel management facilitated complete recovery from severe odontogenic maxillary sinusitis in this case.

Abstract:

Patients with moderate to severe atrophy challenge the surgeon to discover alternative ways to use existing bone or resort to augmenting the patient with autogenous or alloplastic bone materials. Many procedures have been suggested for these atrophied maxillae before implant placement, which include Le Fort I maxillary downfracture, onlay bone grafts and maxillary sinus graft procedures. A zygomatic implant can be an effective device for rehabilitation of the severely resorbed maxilla. If zygomatic implants are used, onlay bone grafting or sinus augmentation would likely not be necessary. The purpose of this article is to review the developments that have taken place in zygomatic implant treatment over years, including anatomic information for installing the zygomatic implants, implant placement techniques, stabilization, and prosthodontic procedures.

Abstract:

Abstract Sinus lift surgery elevation is a procedure that requires radiological maxillary sinus evaluation and procedure planning. The condition of the maxillary sinus before and after sinus lift surgery was assessed. Sixty-five sinuses of 49 patients were included in the study. Preoperative and postoperative cone beam computed tomography (CBCT) scans were performed. The sinuses were analysed radiologically for pathological changes: mucosal thickening, ostia obstruction and accessory opening. The presence of concha bullosa in nasal cavity and septa in the maxillary sinus were recorded. The sinus volume also was measured before and after surgery. Thickened mucosa was found more often in postoperative scans than in preoperative scans (63.1% and 67.7%, respectively). Concha bullosa was found in 30 preoperative scans and in 33 postoperative scans. A correlation between mucosal thickening and ostia obstruction was found. The mean sinus volume decreased after surgery and the changes were statistically significant. In conclusion, changes of the maxillarysinus and nasal cavity can be detected with CBCT. Sinus lift surgery does not excacerebate the existing conditions of the maxillary sinus; however, there is a tendency for pathological features to increase after surgery. Sinus lift surgery is a safe surgery with regard to the maxillary sinus if performed with care.

Abstract:

During implant surgery, when there's insufficient bone in the posterior maxillary region, maxillary sinus elevation is necessary. However, the maxillary sinus contains several anatomically weak structures. Since the surgery is complicated, insufficient understanding of the maxillary sinus anatomy and potential complications can lead to serious consequences such as sinus perforation, ultimately causing implant failure. Depending on surgical methods and indications, maxillary sinus elevation is primarily divided into elevation through alveolar ridge and lateral sinus floor elevation. During surgery, attention should be paid to the course of vessels and nerves, sinus floor morphology, bone thickness, mucosal positioning, and septa within the maxillary sinus. During the surgical process, some complications may occur, such as mucosal perforation, inflammation, bleeding, dizziness, etc. Clarifying their managements in advance helps to improve the success rate of implantation. This article reviewed the anatomically weak structures, potential complications, and their managements to offer clinical treatment strategies.

Abstract:

Maxillary sinus floor elevation via a lateral approach is a predictable technique to increase bone volume of the edentulous posterior maxilla and consequently for dental implants placement. The sinus floor is elevated and it can be augmented with either autologous or xenogeneic bone grafts following an opening bone window created on the facial buccal wall. Maxillary septa are walls of cortical bone within the maxillary sinus. The septa shape has been described as an inverted gothic arch arising from the inferior or lateral walls of the sinus and may even divide the sinus into two or more cavities. Some authors have reported a higher prevalence of septa in atrophic edentulous areas than in nonatrophic ones. Radiographic identification of these structures is important in order to perform the right design of the lateral window during sinus lift. Aim of this investigation is to highlight the correct steps for doing sinus lift surgery in presence of those anatomic variations. Clinicians should always perform clinical and radiographic diagnosis in order to avoid complications related to the sinus lift surgery.

Abstract:

Sinus floor augmentation (SFA) is the most predictable treatment option in the atrophic posterior maxilla. However, exposure of the apical implant body into the maxillary sinus cavity is an occasionally observed phenomenon after SFA. Although most penetrating dental implants remain completely asymptomatic, they may induce recurrent rhinosinusitis or implant loss. Removal of the implant should be considered if there is significant implant exposure that results in prolonged treatment and increased costs. This case report demonstrates a recovery approach using sinus floor reaugmentation without implant removal in a patient with an apically exposed implant into the maxillary sinus cavity.

Abstract:

Previous treatment methods for maxillary sinus carcinoma generally consisted of dissection of maxilla, full dose irradiation, and/or extensive chemotherapy. However, results of such treatment were often poor. Even if patients recover, quality of life (QOL) is significantly reduced as a result of loss of facial structures and functional disability. A retrospective analysis of 42 patients with maxillary sinus carcinoma between 1975 and 1991 was undertaken. All patients underwent pergingival maxillary sinus surgery combined with a standardized total course of pre and postoperative irradiation of 1,600 cGy, together with regional intra-arterial infusion chemotherapy. During the surgery, all visible tumor tissue was removed, and the surrounding tissues were left when possible to facilitate cellular immunity after the surgery. The 5-year survival rate statistically obtained was 100% in Stage II, 100% in Stage III, and 62% in Stage IV patients.

Abstract:

A double-blind clinical trial was conducted to examine the effect of concentrated growth factor (CGF), a new generation of platelet derivatives, on the healing outcome of maxillary sinus floor augmentation during maxillary sinus lift surgery. The study included 9 patients referred to the Tabriz University, Faculty of Dentistry, aged 30-80 years, with bilateral posterior partial edentulous or edentulous maxilla who underwent the procedure using a split-mouth technique. After lifting the Schneiderian membrane, bovine xenograft was randomly applied on one side (for example, left maxillary sinus) and CGF on the other side (for example, right maxillary sinus). Results from alizarin red and hematoxylin-eosin staining methods showed that the percentage of bone formed in the CGF group (112.41±26.34% and 96.16±24.49%, respectively) was significantly higher than in the control group (64.99±24.96% and 60.16±16.39%, respectively) (P<0.05). In addition, after 6 months, the amount of residual graft material in the control group (xenograft) was significantly higher than in the CGF group (P<0.05). These findings demonstrate that the use of CGF during open sinus lift surgery is reliable for the placement of dental implants.

Abstract:

Antimicrobial therapy is a part of the care of patients with chronic sinus disease (CSD), but the etiologic role of microorganisms in this condition is unclear. Twenty patients with CSD undergoing functional endoscopic sinus surgery who had been off antibiotics for at least 1 week before surgery had a maxillary sinus aspirate for quantitative culture for aerobic bacteria and fungi and a semiquantitative culture from the antrostomy of the same maxillary sinus during endoscopic surgery. Six (30%) of the patients had infection of the maxillary sinus diagnosed by the presence of ≥ 103 cfu/mL of organisms in the sinus aspirate (Haemophilus influenzae in two patients and one patient each with Moraxella catarrhalis, α-streptococcus, mixed oropharyngeal flora, or Alternaria sp.). All antrostomy specimens obtained by nasal endoscopy during surgery were positive, but the antrostomy cultures did not correlate with the sinus aspirate cultures from the same sinus. Staphylococcus aureus and/or Gram negative rods in eight antrostomy cultures did not predict the presence of these pathogens in any of the maxillary sinus aspirates. Conversely, the bacteria detected with the quantitative aspirate culture in five of the six infected sinuses were not found in the antrostomy specimen; only the fungal sinus infection correlated with the antrostomy culture. Infection of the maxillary sinuses occurred in patients with both limited and severe disease by CT imaging. About one third of patients with CSD necessitating surgery had microbial infection of the maxillary sinus, but antrostomy cultures obtained via endoscopy did not predict the organisms infecting the sinus.

Abstract:

The maxillary sinus is a pneumatized anatomical structure located bilaterally in the anterior region of the maxilla. The occurrence of displacement of foreign bodies in the maxillary sinus is not a common condition and when present, it is associated with car accidents, fire arm accidents, psychiatric disorders and iatrogenies in surgical procedures. The removal of the foreign body is carried out in order to prevent infections, and the permanence of the foreign body may offer immediate or chronic damage. Access to the maxillary sinus is most commonly performed using the Caldwell-Luc access technique. Thus, the objective of the study is to report a clinical case of surgical removal of a maxillary third molar from the interior of the maxillary sinus using the caldwell-luc access technique, with the aid of a surgical guide in order to conduct a safer and less invasive surgery.

Abstract:

Abstract Antral septa of the maxillary sinus occurs in approximately one third of patients undergoing posterior maxillary bone augmentation and is considered a relative contraindication for lateral maxillary window (“hinge osteotomy”). We present the results of 26 consecutive cases of patients with septated maxillary sinus who underwent minimally invasive antral membrane balloon elevation (MIAMBE) followed by bone augmentation and implant fixation. After undergoing preprocedural assessment and signing an informed consent, 57 consecutive patients were referred for posterior maxillary bone augmentation. Alveolar crest exposure (via 3-mm osteotomies), MIAMBE, and bone augmentation were followed by implant placement and primary closure (executed at the same sitting). Implant loading was done 6–9 months later. Twenty-six out of 57 (45.6%) patients had significant septa (detected on computed tomography) in the designated augmentation region. Twenty-four (92%) concluded the initial procedure successfully. Two patients had membrane tear requiring procedure abortion. Mean procedure time was 48 ± 23 minutes. Incremental bone height consistently exceeded 10 mm, and implant survival of 95.2% was observed at 6–9 months. MIAMBE can be applied to patients in need of posterior maxilla bone augmentation in the presence of septated maxillary sinus with high procedural success, low complication rate, and satisfactory bone augmentation and implant survival. MIAMBE should be an alternative to the currently employed methods of maxillary bone augmentation, especially in the presence of septated maxilla.

Abstract:

Background: Canine fossa trephine (CFT) is an adjunctive technique to sinus surgery in patients with recalcitrant maxillary sinusitis. CFT allows for disease clearance in areas of the maxillary sinus that are hard to reach with standard endoscopic techniques. The objective of this study was to compare the surgical outcome of CFT to standard middle meatal antrostomy (MMA) in matched patients with the severely diseased maxillary sinus. Study design: Prospective clinical study Methods: Patients undergoing sinus surgery were enrolled in either the CFT or MMA group. All patients had nasal polyps, Lund Mackay score of 2 in the maxillary sinus, and nasal endoscopy showing the maxillary sinus full of polyps. The patients were followed and the maxillary sinus was graded endoscopically at 3, 6 and 12 months after the surgery. Length of surgery, disease recurrence and need for revision surgery was documented. Results: Forty-two CFTs and MMA were performed in each group. At 6 and 12 months the CFT group demonstrated statistically significant improvement in nasal endoscopy scores. Six patients recurred by the one year mark in the MMA group, 4 of which underwent revision surgery. In the CFT group 2 patients recurred, one who underwent a unilateral revision CFT. Furthermore the CFT did not prolong the surgical time and was often faster than performing a MMA. Conclusion: CFT allows for clearance of all gross disease in the maxillary sinus and appears to improve postoperative outcome at 6 and 12 months and decrease the need for revision surgery.

Abstract:

Importance: Safe entry into sphenoid sinus is critical in endoscopic sinus and skull base surgery. A number of surgical landmarks have been used to identify the sphenoid sinus ostium during endoscopic endonasal surgery with variable reliability and intraoperative feasibility. Objective: To determine if the posterior wall of the maxillary sinus is a reliable landmark to determine the depth of the sphenoid sinus ostium during anterior to posterior dissection. Design, Setting, and Participants: Prospective study of adult patients undergoing endoscopic sinus surgery between August 2016 and September 2017. Measurements were made intraoperatively between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Main Outcomes and Measures: The primary measurement is the distance between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Additional data points included age, gender, surgical indication, and primary versus revision endoscopic sinus surgery. Results: Forty-five patients (38% male, 62% female) with an average age of 56 were enrolled, resulting in 88 operated sides. The average distance between the depth of the posterior wall of the maxillary sinus and the sphenoid ostium was 1.5 mm ± 1.4 mm. The most common position of the sphenoid sinus ostium was posterior to the level of the posterior maxillary sinus wall (54%), followed by same level (23%) and anterior (23%). There was no significant difference between different disease states ( P = .75) and between primary and revision cases ( P = .13). Conclusions and Relevance: The posterior wall of the maxillary sinus serves as an adjunctive intraoperative landmark to determine the depth of the sphenoid sinus ostium. While the posterior wall of the maxillary sinus approximates the depth of the sphenoid sinus ostium, the relative position is variable and can be anterior or posterior.

Abstract:

Background: Midfacial fractures frequently involve the maxillary sinus, leading to maxillary sinus pathology. We aimed to examine the incidence and contributing factors of maxillary sinus pathology in patients who underwent open reduction and internal fixation (ORIF) for midfacial fractures.Methods: A retrospective analysis was conducted on patients who underwent ORIF for midfacial fractures at our department over the past 10 years. The incidence of maxillary sinus pathology was identified clinically and/or by computed tomography findings. Factors that significantly influenced the groups with and without maxillary sinus pathology were examined.Results: The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was found to be 11.27%, with sinusitis being the most common pathology. Maxillary sinus pathology was significantly associated with the presence of a blowout fracture involving both the medial and the inferior orbital walls. Factors such as sex, age, diabetes mellitus, hypertension, smoking, inflammatory disease, follow-up period, use of absorbable plates, and use of titanium plates did not have a significant impact on the development of maxillary sinus pathology.Conclusion: The incidence of maxillary sinus pathology in patients who underwent ORIF for midfacial fractures was relatively low, and in most cases, it resolved without the need for specific treatment. Consequently, there may not be a significant need for concern regarding postoperative maxillary sinus pathology.

Abstract:

In patients with missing maxillary posterior teeth, the negative pressure generated by breathing leads to an increase in the gasification of the maxillary sinus cavity, as well as the absorption of alveolar bone due to the lack of physiological stimulation due to missing teeth. This often leads to insufficient bone height during implant restoration in the maxillary posterior tooth area, and maxillary sinus floor elevation surgery can effectively solve this problem. At present, there are two main techniques for lifting the maxillary sinus floor: internal lifting through the top of the alveolar ridge approach and external lifting through the lateral wall approach. Among them, the maxillary sinus alveolar ridge lifting surgery is widely used due to its advantages of small wound size, short surgical time, fewer postoperative complications, low cost, and easy acceptance by patients. With technological innovation, the indications for maxillary sinus floor elevation surgery have gradually expanded to cases with residual bone height (RBH) greater than 2 mm.

Abstract:

Maxillary sinus floor augmentation is considered to play a critical role in dental implant treatment. Although many complications, such as maxillary sinusitis and infection, are well known, few reports are available on the risk of surgical ciliated cyst following the procedure. Here, we report a case of surgical ciliated cyst following maxillary sinus floor augmentation. A 55-year-old Japanese woman was referred to our hospital because of alveolar bone atrophy in the bilateral maxilla. We performed bilateral maxillary sinus floor augmentation by the lateral window technique without covering the window. The Schneiderian membrane did not perforate during the operation. She returned to our hospital after 9 years due to swelling of the left buccal region. Computerized tomography revealed a well-defined radiolucent area with radiodense border intraosseously localized in the left maxilla. We performed enucleation of the cyst with the patient under general anesthesia. Histological examination of the specimen showed a surgical ciliated cyst. In conclusion, the course of this patient has 2 important implications. First, the sinus membrane entrapped in the grafted bone without visible perforation and or tearing can develop into a surgical ciliated cyst. Second, there is a possibility that covering the lateral window tightly might prevent the development of a surgical ciliated cyst.

Abstract:

The loss of single or multiple teeth in the maxillary posterior region usually leads to alveolar bone resorption, atrophy, and maxillary sinus cavity gasification, resulting in insufficient vertical bone height of the maxillary posterior alveolar bone, which brings great difficulties to tooth implantation. Maxillary sinus floor lifting is an important method to solve the posterior maxillary bone mass deficiency, which can be divided into internal lifting and external lifting. In order to avoid the occurrence of complications such as maxillary sinus mucosa perforation and facilitate the selection of surgical methods, it is particularly important to accurately understand the anatomical characteristics of maxillary sinus before surgery. Maxillary sinus cyst is the most common benign disease of maxillary sinus. It has always been considered as an absolute contraindication for maxillary sinus floor elevation bone grafting, which seriously restricts the possibility of maxillary sinus bone increment. This article reviews the research progress of maxillary sinus cyst and maxillary posterior dental implantation at home and abroad.

Abstract:

Endoscopic sinus surgery (ESS) is the main surgical approach in the treatment of chronic rhinosinusitis (CRS) after failure of medical treatment. ESS is based on the theory that obstruction of the maxillary sinus ostium is mainly behind the pathogenesis of CRS. Controversy remains concerning the enlargement of the natural maxillary sinus ostium. The aim of this study was to compare computed tomography (CT) findings after preservation or enlargement of the maxillary sinus ostium. Thirty patients with non-polypous CRS underwent randomized endoscopic sinus surgery with uncinectomy on one side and additional middle meatal antrostomy on the other side. Lund-Mackay (LM) scores and the ostium diameters were analysed from CT scans taken preoperatively and nine months postoperatively, and were used for comparison of the two operative techniques. In addition, the correlation between CT findings and subjective outcomes was studied. Comparison of the preoperative and postoperative CT scans revealed that significant reduction of LM score was achieved on both sides, regardless of the type of procedure performed. The postoperative area of the ostium remained significantly larger on the antrostomy side compared to the uncinectomy side. A large maxillary sinus ostium size seems to associate with lower postoperative LM score, but does not seem to provide superior symptom relief.

Abstract:

The implant-supported prosthetic rehabilitation of the posterior maxilla may require sinus-grafting procedures due to poor quality and low volume of bone. This can be accomplished using a “lateral window” sinus augmentation or with an osteotome sinus floor elevation (OSFE). The hydrodynamic ultrasonic cavitational sinus lift (HUCSL) (Intralift) is derived from the osteotome technique and allows the reduction of some of the traumatic effects of the osteotome technique. The aim of this study was to compare OSFE and the HUCSL procedures on fresh human cadaver heads. Primary outcomes were the height and width of the grafting area in the sinus floor area. Eighty-four maxillary sinuses were selected. On each fresh cadaver head, 2 sinus lifts were done using OSFE and HUCSL in the maxillary sinuses. Computerized tomography scans were performed on each head before and after the surgeries. Measurements were done on radiologic pictures using dedicated software, and the integrity of the sinus membrane was observed after dissecting the maxillae. The use of HUCSL resulted in a significantly higher sinus floor augmentation in the mesio-distal and bucco-palatal direction compared with the osteotome technique (P < .001). There was no correlation between mesio-distal and bucco-palatal diameters of sinus floor augmentation when only the osteotome protocol was considered (r = 0.27 and P = .08). In contrast, the mesio-distal and bucco-palatal diameters of floor augmentation were correlated when the HUCSL protocol was considered (r = 0.79, P < .001). HUCSL represents a good alternative method for sinus floor elevation.

Abstract:

OBJECTIVE: To evaluate change of the maxillary sinus volume according to patient age and gender by using a 3-dimensional (3-D) reconstruction of computed tomography images. STUDY DESIGN AND SETTING: One hundred seventy-three people (totaling 238 maxillary sinuses) who had undergone paranasal sinus CT scan between December 2000 and November 2003 and had no evidence of inflammation or hypoplasia in the CT finding and had no specific history of paranasal sinus surgery or maxillofacial trauma were retrospectively analyzed. The 3-D reconstruction images were obtained by using a surface-rendering technique (Vworks; CybeMed, Seoul, Korea) on a personal computer. The mean volume of maxillary sinus was evaluated according to patient chronologic age and gender. The ratio of the maximum horizontal and half-horizontal extension for the estimation of the morphological change of maxillary sinus and the degree of descent of the sinus below the nasal floor were evaluated in the 3-D image. RESULTS: The development of the maxillary sinus continued until the 3rd decade in males and until the 2nd decade in females. The mean maxillary sinus volume in early adults was 24,043 mm 3 (males) and 15,859.5 mm 3 (females). There was a significance difference in the sinus volume ( P < 0.05) according to gender, and there was a significant difference in the maxillary sinus volume according to age before it reached maximum. After its maximum growth period, however, there was no significant difference in the volume change of maxillary sinus and the descent below the nasal floor between two adjacent groups. CONCLUSIONS: The growth of the maxillary sinus continues until the 3rd decade in males and the 2nd decade in females. Therefore, a maxillary sinus operation affecting the bony structures before these ages might affect the development of the sinus and needs to be performed carefully

Background: Maxillary sinusitis can arise after sinus floor elevation surgery and should be treated immediately to prevent further complications which included dental implants failure, graft lost, and oro-antral fistula. This is the first systematic review to assess the incidence, causes, and treatment of sinusitis after sinus lift surgery. Materials and methods: An electronic search included MEDLINE (PUBMED) data base site was carried out for articles involving development of sinusitis after sinus lift surgery from September 1997 up to April, 8, 2017. The search was done and reviewed by two independent authors. Results: The total results of electronic search were (182) abstracts and articles, the extracted articles which involved development of sinusitis after sinus lift surgery were (25) studies. Of the 25 articles only (8) articles fit the inclusion criteria. Maxillary sinusitis was calculated for all selected studies and it was ranged from 2.12% to 12.7% with average of 5.4 %. Conclusion: Maxillary sinusitis could be developed after sinus lift surgery with average of 5.4 % and the patients with previous maxillary sinus disease showed to be at increased risk of sinusitis after sinus lift surgery.

Upon examination, he had a visual field defect and a best corrected visual acuity of 0.6 in the right eye. The patient was diagnosed with a postoperative cheek cyst originating from the maxillary sinus. The cyst developed because of radical maxillary sinus surgery. Computed tomography showed a mass originating from the maxillary sinus. After endoscopic sinus surgery, the best corrected visual acuity of the right eye improved to 1.0 and the periorbital edema was reduced.Conclusion: In patients with orbital involvement of a maxillary sinus cyst, radiographic examination and surgical history of the postoperative cheek cyst can be diagnostic.

Abstract:

The effects of pediatric sinus surgery on craniofacial growth have not been established. This study was designed to determine whether sinus surgery influences midfacial growth in New Zealand white rabbits. Surgery was performed on five groups of six rabbits each: Group 1—bilateral external dorsal approach to the maxillary sinus with enlargement of the sinus ostium and removal of the uncinate process; Group 2—bilateral external dorsal approach to the maxillary sinus; Group 3—unilateral external dorsal approach to the maxillary sinus with enlargement of the sinus ostium and removal of the uncinate process; Group 4—unilateral external dorsal approach to the maxillary sinus; Group 5—no operation. Rabbits were killed as adults, and dried skull measurements were performed using a Polhemus 3-space digitizer. Statistically significant regional restriction of midfacial growth was demonstrable when comparing Groups 1–4 with Group 5, and between sides in Groups 3–4. Enlargement of the sinus ostium and uncinectomy caused foreshortening of the snout on the operated side in Group 3. This effect was not observed following the approach alone in Group 4. These results suggest that midfacial growth is affected by sinus surgery in rabbits. Further animal studies should be done to test this hypothesis, and in the interim, a conservative approach to sinus surgery in children would be prudent.

Abstract Several regenerative therapies have been used for maxillary sinus grafting. However, recent advances in modern bone tissue engineering techniques have been evaluated. The aim of this histologic report was to evaluate the bone obtained by a culture of autogenous osteoblasts seeded on polyglycolic-polylactid scaffolds in maxillary sinus augmentation. A 56-year-old partially edentulous male with severe atrophy of the posterior maxilla received 6 polyglycolid-polylactid disks (8 mm diameter × 2 mm depth, Oral Bone), each carrying 1.5 million autogenous osteoblasts into the depth of the sinus cavity. After 6 months healing, a bone core was harvested and histologically evaluated. The augmented maxillary sinus with engineered bone presented a mean of 28.89% and 71.11% of bone and medullary spaces, respectively. Data from this case report demonstrate that the newly formed bone provided by engineered bone tissue allowed proper initial stability for dental implant placement. However, the role of this new bone in the long-term success of dental implant anchorage needs further investigation.

Abstract:

This case series describes an alternative approach for removing ectopically erupted tooth in the maxillary sinus using an improved endoscopic approach known as modified endoscopic-assisted sinus surgery (MESS). We reviewed medical charts and radiographs of patients who underwent surgical removal of an ectopic tooth in the maxillary sinus using MESS. The surgical technique consisted of creating a bony window in the maxillary sinus wall with a pre-adapted microplate, which was repositioned after the tooth was removed. For all the patients included in this study, there were no postoperative complications clinically and radiographically. At the time of microplate removal, satisfactory bone regeneration was observed around the bony window margins of the maxillary sinus wall. MESS is an effective technique that modifies and integrates the techniques of the conventional Caldwell-Luc procedure (CLP) and functional endoscopic sinus surgery (FESS) and can be used to remove ectopic tooth in the maxillary sinus by avoiding the risk of postoperative sinus-related complications.

Abstract:

Maxillary sinus floor elevation using autologous or alloplastic bone grafting is often performed for implant treatment of maxillary molars; however, issues related to the donor site and complications such as infection have been reported. We performed maxillary sinus floor elevation using poly-L-lactic acid (PLLA) as a space-making material in patients with an insufficient bone mass (<3 mm) for simultaneous implantation between the alveolar crest and floor of the maxillary sinus and evaluated the newly formed bone. Conventional antrostomy of the maxillary sinus from the lateral wall was performed, and PLLA was placed on the floor of the maxillary sinus after elevating the sinus membrane. Six months after surgery, the bone mass and density were measured using quantitative computed tomography, and histological evaluation was performed. No complications were recorded. Radiological findings showed a bone-like radiopaque appearance, and histological examination revealed new bone formation in all patients. In cases with insufficient bone mass prior to simultaneous implant placement, this method of maxillary sinus augmentation allows for sufficient bone augmentation without bone grafting.

Maxillary sinus mucocele, which appears more than 10 years after Caldwell-Luc surgery, is very rare in the United States or Europe. However, it is very common in Japan. It is called “postoperative maxillary sinus mucocele” or “postoperative maxillary cyst.” In this paper, postoperative maxillary sinus mucoceles, which protruded into the orbits, are reported. One patient, a 50-year-old man, underwent Caldwell-Luc surgery 31 years ago, and the other patient, a 61-year-old woman, underwent Caldwell-Luc surgery at the age of 18. The incidence of this disease, symptoms, diagnosis and treatment are discussed in this paper.
