Abstract:

OBJETIVO: O objetivo deste trabalho foi verificar a freqüência e os tipos de variações anatômicas do complexo ostiomeatal. MATERIAIS E MÉTODOS: Foram revisadas 200 tomografias computadorizadas de pacientes com suspeita clínica de sinusopatia. RESULTADOS: Observamos um ou mais tipos de variações anatômicas em 83,5% dos pacientes, as mais freqüentes envolvendo o corneto médio (84%) e o septo nasal (34%). Outras variantes anatômicas comuns encontradas foram a presença de aeração do agger nasi e células etmoidais infra-orbitárias (células de Haller). CONCLUSÃO: As variações anatômicas do complexo ostiomeatal anterior são muito corriqueiras. As mais freqüentes envolvem o corneto médio e o septo nasal.

Abstract:

A tomografia computadorizada constitui, hoje, o método de escolha para a avaliação dos seios paranasais e fossas nasais e de suas variações anatômicas. Postula-se que essas variações possam obstruir as vias de drenagem de muco, predispondo à rinossinusite crônica. Contudo, esse conceito é ainda controverso e a simples presença da variação anatômica não estabelece necessariamente a etiologia da rinossinusite. Dos três subtipos de concha média bolhosa, a variante bulbosa é a única que parece ter forte associação com a geração de sintomas. As dimensões da variação e a sua associação com a obliteração das vias de drenagem do complexo ostiomeatal parecem ser também muito importantes. Sinais tomográficos de doença sinusal do mesmo lado da variação anatômica reforçam a possibilidade de que esta interfira com o processo de drenagem de muco. A tomografia computadorizada permite estudo detalhado das variações anatômicas e é método indispensável na determinação da conduta e no planejamento de estratégias cirúrgicas. A análise tomográfica deve basear-se na identificação das variações, definição de suas dimensões e sua associação com obliteração dos óstios de drenagem e alterações tomográficas sinusais ipsilaterais.

Abstract:

Padronizando a nasofibroscopia flexível detalhada, podemos avaliar as variações anatômicas de estruturas do complexo ostiomeatal, tais como, agger nasi, processo uncinado, bula etmoidal e concha nasal média. OBJETIVO: Avaliar as variações anatômicas em relação ao sexo, lado acometido e entre diferentes faixas etárias de acordo com o desenvolvimento e pneumatização do etmóide. FORMA DE ESTUDO: Clínico prospectivo. MATERIAL E MÉTODO: No presente trabalho, foram estudados 500 doentes com queixas nasais (1000 meatos médios). RESULTADOS E CONCLUSÕES: As conchas nasais médias globosas, extensiva e bulbosa, foram as variações anatômicas mais freqüentes, seguidas pelo agger nasi hipertrofiado, concha nasal média paradoxal e processo uncinado angulado ou projetado medialmente. O agger nasi, a concha média globosa extensiva, concha nasal média paradoxal, o processo uncinado angulado ou projetado medialmente e a bula etmoidal hipertrofiada tendem a ser bilaterais, enquanto a concha média globosa bulbosa tende a ser unilateral. Houve correlação significante entre a prevalência do agger nasi hipertrofiado e das conchas nasais médias globosas tipo extensiva e bulbosa ipsilateralmente. Houve correlação significante entre a prevalência da concha nasal média globosa tipo extensiva e da concha nasal média globosa tipo bulbosa contralateralmente. Não houve correlação significativa entre a prevalência das variações anatômicas do agger nasi, processo uncinado, bula etmoidal e concha nasal média isoladamente ou associadas, em relação ao sexo.

Abstract:

Polipose nasossinusal (PNS) é uma entidade de etiologia controversa, caracterizada por uma condição inflamatória da superfície mucosa das fossas nasais e seios paranasais, bilateralmente. A queixa principal do paciente consiste na obstrução nasal e, ao exame físico, observam-se freqüentemente massas polipóides ocupando as cavidades nasais em extensões variáveis. Além da rinoscopia anterior e da endoscopia nasal, o uso da tomografia computadorizada (TC) torna-se necessário para avaliação das fossas nasais e da presença ou não do acometimento dos seios paranasais por essas massas, bem como a sua extensão. Este trabalho tem como objetivo avaliar a concordância interobservadores, por meio da análise da tomografia computadorizada, de 32 casos de PNS. FORMA DE ESTUDO: Clínico prospectivo. CASUÍSTICA E MÉTODOS: Foram avaliadas 32 TC de pacientes portadores PNS por dois observadores experientes, separadamente, em relação à presença ou não de 3 sinais tomográficos sugestivos dessa doença: (1) alargamento infundibular do complexo ostiomeatal, (2) abaulamento lateral da lâmina papirácea e (3) apagamento do trabeculado ósseo etmoidal. RESULTADOS: Observou-se Qui-quadrado não significante para o primeiro e segundo sinais (p=0,7055 e p=0,2057) e significante para o terceiro (p=0,0040). Contudo, o coeficiente de correlação de Kendall entre os dois observadores foi significante para os três sinais tomográficos acima citados (p<0,001; p=0,01; p=0,03 respectivamente). CONCLUSÃO: A maior concordância entre os observadores esteve presente no alargamento infundibular com maior freqüência de positividade desse sinal.

Abstract:

Abnormalities in the ostiomeatal complex (OMC) constitute a major factor in the pathogenesis of sinusitis. They may be appreciated by the classical anterior rhinoscopy, the endoscopic examination, and/or the coronal computed tomographic (CT) scan. Cases are seen, however, with clinical and radiological evidence of blockage of the OMC with no clinical sinusitis. Conversely, cases with definite sinusitis may have negative clinical examination and CT scans. Some patients continue to have sinusitis despite anatomically successful endoscopic surgery. It should be remembered that sinusitis may be caused by or facilitated by factors other than obstructions of the OMC. The decision to surgically treat sinusitis remains a clinical one based on a comprehensive evaluation.

Abstract:

The aim: Was to evaluate the anatomical variability of the frontal and maxillary sinuses, ostiomeatal complex components (OMC) and to identify factors that contribute to complications of inflammatory processes and development of odontogenic maxillary sinusitis. Materials and methods: The study involved assessment of 100 spiral computed tomograms (SCT) of human patients without pathological processes in the PNS area. The basic parameters of the anatomical structure of the ostiomeatal complex (the area of the hooked process and the middle nasal conch, their transverse dimensions, the density and dimensions of the natural connection), the thickness and the density of the lower wall of the maxillary and frontal sinuses were determined. These parameters were investigated by the method of uncertainty calculation. Results: The findings showed that the bone density of the maxillary sinus on the left was 57.713 ± 440.356 Hu (minimum), 1101.507 ± 613.4882 Hu (maximum); 96.2752 ± 395.0 and 1028.691 ± 620.4051 on the right, respectively, the density of the inferior frontal sinus wall on the right was 5.5179 ± 276.43 and 831.1607 ± 732.274, on the left 12.069 ± 310.56 and 898.293 ± 748, respectively. In the same way, the probable OMC structure parameters, in the range ± U at the confidence level p = 0.95, were calculated. Conclusions: Thus, some variants of the anatomical structure of the ostiomeatal complex can be a prerequisite for hypoventilation of PNS and, as a consequence, lead to inflammatory processes in them. Features of the same structure of the walls of the PNS are a prerequisite for the propagation of the inflammatory process in the surrounding tissues and the development of complications.

Abstract:

A goal in ethmoid sinus surgery is to ventilate the sinuses by complete removal of all diseased tissue in the ostiomeatal complex. Many surgeons routinely preserve the middle turbinate because they feel it is not part of the disease process and its structure is very important for proper nasal physiology. Other surgeons frequently remove such to facilitate exposure to the ostiomeatal complex and, more importantly, they postulate that it is chronically diseased. This study involved 22 adult patients with CAT scan Stage I:2, II:2, III:5, and IV:13 sinus disease who underwent intranasal ethmoidectomy with resection of the middle turbinate. Three additional turbinate resections performed for other reasons in patients with negative radiological findings served as controls. Histologic findings demonstrated the middle turbinate was chronically diseased to a similar degree as the ethmoids in all 22 patients. Respiratory mucosa without significant pathologic change was found in the controls. This suggests resection of the middle turbinate may be essential, especially in CA T scan Stage III and IV disease. Persistent disease in the middle turbinate may enhance the tendency for synechia formation with the lateral nasal wall and may also account for failure to relieve symptoms in some patients. The question of reversibility of disease in the middle turbinate following ostiomeatal complex surgery remains unanswered.

Abstract:

Objectives 1) Learn which paranasal sinuses are involved in chronic rhinosinusitis in children. 2) Be able to customize surgical treatment based on those findings. Methods Retrospective review of children who had sinus surgery over a period of 10 years. 76 children whose age ranged between 3 and 14 years had their CT scans reviewed to determine which sinuses were diseased. All children had a CT scan because of failure of medical management and were considered for surgery. Outcome was to determine which sinuses were developed and of those, which ones were diseased and what was the severity of the disease. Results The maxillary sinuses were the most common sinuses involved in children with chronic rhinosinusits (92%). The ostiomeatal complex was next most common area involved in these children (88%). Conclusions The maxillary sinuses, followed by the ostiomeatal complex, were the most common areas involved in children with chronic rhinosinusitis. Initial surgical management of these children should then be based on those findings.

Abstract:

The introduction of computerized tomography in the identification of sinonasal pathology and associated anatomic variants has contributed to a greater understanding of the factors leading to ostiomeatal complex (OMC) obstruction and chronic sinus disease. The OMC and paranasal sinus regions were prospectively evaluated in 150 consecutive patients as a function of the degree of nasal septal deviation and compared with matched controls. These data were correlated with paranasal sinus disease, lateral nasal wall findings, and middle turbinate abnormalities. An increased incidence and severity of bilateral chronic sinus disease was present with increasing septal deviations (p < 0.05). Similarly, patients with increasing nasal septum deviations were noted to have a higher incidence of OMC obstruction (p < 0.05). Ostiomeatal complex obstruction in the direction of septal angulation was associated with nasal septal deformity; however, contralateral OMC obstruction was associated with middle turbinate and lateral nasal wall abnormalities (p < 0.05). The evaluation of the degree of septal angulation has helped better understand the factors contributing to chronic sinus disease and OMC obstruction.

We report a case of cavernous hemangioma originating in the maxillary sinus. This is an unusual location for hemangioma, and this case also had a rare presentation involving bone erosion. The substantial bone destruction and resultant widening of the right ostiomeatal complex made it difficult to differentiate this cavernous hemangioma from malignant epithelial tumors.

Abstract:

Abstract BACKGROUND. The ostiomeatal complex (OMC) is the anatomical region situated between the middle turbinate and the lateral nasal wall, at the level of the middle meatus. Common anatomical variations of OMC are concha bullosa, hypertrophy of the uncinate process and of the bulla ethmoidalis and Haller’s cell. Our study was aimed to investigate the prevalence of these conditions and their relations to different symptoms. MATERIAL AND METHODS. The study is a retrospective descriptive study based on 256 files of patients who were hospitalized and treated for OMC pathology in our clinic between January 2009 and January 2014. The data acquired were included into Excel Worksheets and statistically analyzed using GraphPad Software. RESULTS. The most common finding was concha bullosa (63.67%), followed by hypertrophy of the bulla ethmoidalis (10.93%) and of the uncinate process (10.15%). Haller’s cell was found in only 3% of cases. The most common symptom for all patients was nasal obstruction, followed by nasal discharge. The majority of symptoms improved after functional endoscopic sinus surgery for OMC drainage. CONCLUSION. OMC pathology is a frequent indication for functional endoscopic sinus surgery. The most common condition that determines blockage of OMC and need for surgical treatment is concha bullosa. The most common complaint of patients with OMC pathology is nasal obstruction.

Abstract:

AbstractThe role of the anterior ethmoids in the pathogenesis of chronic maxillary sinusitis is still a subject of controversy. Although the symptoms of maxillary sinusitis may be clinically dominant, many previous studies have showed that the origin of this disease was, in most cases, located within the anterior ethmoid region.This study included 100 Egyptian patients, suffering from chronic maxillary sinusitis (confirmed by maxillary sinoscopy), who were subjected to ‘systematic nasal endoscopy’. It was found that all cases of chronic maxillary sinusitis were associated with anatomical variations and/or pathological abnormalities of ‘the ostiomeatal area’. It is recommended, therefore, that during the diagnosis and treatment of chronic maxillary sinusitis, attention should be given to the region of the middle meatus and anterior ethmoid complex (or ‘ostiomeatal area’) for any anatomical variations and/or pathological abnormalities in order to avoid recurrence of maxillary sinusitis. This is the basis of the procedure of functional endoscopic sinus surgery.

Abstract:

<p class="abstract"><strong>Background:</strong> In ancient times the paranasal sinuses, without any anatomical differentiation, were thought to be a system of hollow spaces through which mucus produced by the brain was drained. Leonardo da Vinci in Milano in 1489 was the first to prepare and draw anatomical specimens of the paranasal sinuses; the drawings, however, only became accessible to scientific evaluation as late as 1901.</p><p class="abstract"><strong>Methods:</strong> All adult patients (more than 20 years of age) attending the Outpatient department at ENT, diagnosed to have chronic rhinosinusitis, willing to undergoing Computed Tomographic evaluation were included in this study. Sample of 50 was selected using purposive sampling technique. All CT scans were obtained with GE Brightspeed scanner (16 slice MDCT scanner). Coronal sections were performed with the patients in prone position, with extended neck and the plane perpendicular to the infraorbitomeatal line.</p><p class="abstract"><strong>Results:</strong> Agger nasi was the most common variation seen in 72% cases followed by dwviated nasal septum in 66% patients. Other variations found were lateral attachment of uncinate process in 54%, uncinate attachment to skull base in 33%, concha bullosa in 32%, overpneumatized bulla ethmoidalis in 21%, medial attachment of unicinate process to middle turbinate in 13%, paradoxical bent middle turbinate in 11%, haller cell seen in 6%. 56% had type I frontoethmoidal cells, 29% had type II, and 15% had type III frontoethmoidal air cells.</p><p><strong>Conclusions:</strong> The presence of anatomical variants does not indicate a predisposition to sinus pathology but these variations may predispose patients to increased risk of intraoperative complications.

Abstract:

The clinical and radiologic records of 500 sequential patients who underwent screening sinus CT as a prelude to possible functional endoscopic sinus surgery (FESS) were reviewed in order to answer three clinical-radiologic questions: (1) Can distinct radiologic patterns of inflammatory disease be identified on screening sinus CT (SSCT)? (2) If so, what are these radiologic patterns? (3) How do the findings seen on SSCT influence the endoscopic surgical plan? Five basic radiologic patterns of sinonasal inflammatory disease were identified among the 500-member patient population. These were based on known patterns of mucociliary drainage correlated with obstructive patterns observed on the CT scans. These radiologic batterns included: (1) Infundibular (129 of 500 or 26%), (2) ostiomeatal unit (126 of 500 or 25%), (3) sphenoethmoidal recess (32 of 500 or 6%), (4) sinonasal polyposis (49 of 500 or 10%), and (5) sporadia (unclassifiable) (121 of 500 or 24%) patterns. Normal SSCT was seen in 133 of the 500 patients (27%). Although the ostiomeatal unit is the central feature in sinonasal inflammatory disease, obstruction of the infundibulum alone or of the sphenoethmoidal recess can cause unique inflammatory patterns of disease that require tailored FESS. The identification of sinonasal polyposis raises a different set of FESS considerations. The sporadic pattern of inflammatory disease, when identified, creates unique FESS challenges, depending on the specific sinus or sinuses involved. Assignment of these patterns to the individual case also assists in patient management by grouping patients into nonsurgical (normal CT), routine (infundibular, ostiomeatal unit, and most sporadic patterns) and complex (sinonasal polyposis and sphenoethmoidal recess) surgical groups.

Abstract:

The anatomical abnormalities of the nose and paranasal sinuses are the most common causes of rhinosinusitis. These anatomical variations can cause obstruction of the ostiomeatal complex (OMC) and interfere with the mucociliary clearance which allows the occurrence of chronic rhinosinusitis. Knowing the anatomic variations of the nose and paranasal sinuses in rhinosinusitis patients whose undergo operative procedure at Sanglah Provincial General Hospital is important because it can be used as a reference for proper intervention to treat rhinosinusitis. This research is a descriptive study in the Ear Nose Throat - Head Neck Departement, Udayana University Medical School / Sanglah Provincial General Hospital Denpasar, from January 2018 to December 2018. The research location is at the ENT clinic, Sanglah Hospital, Denpasar. This research will be conducted in approximately 2 months (January 2019 to February 2019). The sample from this study was all rhinosinusitis patients who underwent operative procedure, both male and female for the period of 1 January – 31 December 2018. Based on the results of the research data, it was found that the most anatomic variation was septal deviation which was 24 people Anatomic variations cause chronic sinusitis by causing obstruction in the ostiomeatal complex (OMC) and affecting the mucociliary transport pattern. The most anatomical variation in this study is septal deviation.

Abstract:

According to the data of domestic and foreign authors, the incidence of maxillary sinusitis has doubled over the past 10 years, and the proportion of patients hospitalized in ENT hospitals is increasing annually by 1.5–2.0%, moreover, rhinology and rhinosurgery are the main areas of work of the ENT hospital currently. An important role in the occurrence of chronic maxillary sinusitis is played by the condition of the nasal cavity, especially the area of the ostiomeatal complex. For more than 30 years, rehabilitation of patients with complete or partial absence of teeth using subantral grafting and dental implantation has been widespread in Russian dental practice. Odontogenic maxillary sinusitis is increasingly found as a complication of dental implant treatment in the upper jaw. Patients usually get consultations with an otorhinolaryngologist already with the appearance of complications, and this reduces the effectiveness of dental operations. The question of diagnosis of maxillary sinusitis and insufficient preoperative preparation before implant treatment at the dentist remains open. When preparing a patient for implant treatment at the dentist, important components are the otorhinolaryngological examination and computed tomography of the paranasal sinuses, which can reveal a violation of the architectonics of the nasal cavity, the ostiomeatal complex and the pathology of the maxillary sinuses.

Abstract:

Background A multicenter study (BREATHE I - Entellus Medical, Inc.) was performed to assess the safety and outcomes of a new, less invasive system that uses direct endoscopic visualization to facilitate balloon dilation of the maxillary sinus ostia and ethmoid infundibulum. General anesthesia was avoided in most subjects to assess feasibility of performing transantral ostial dilatation in an office setting. Methods Subjects with chronic rhinosinusitis of the maxillary sinuses alone or maxillary and anterior ethmoid sinuses underwent baseline evaluation including CT imaging and symptom assessment using the Sino-Nasal Outcome Test (SNOT 20). Subjects underwent transantral balloon dilation and follow-up evaluation at 1 week, 3 months, and 6 months post-procedure. Results Thirty subjects were treated at three centers. Fifty-five of 58 maxillary ostia were successfully treated for a procedural completion rate of 94.8%. Ninety-seven percent of the procedures were completed under local anesthesia with or without minimal intravenous sedation. There were no device-related serious adverse events or unanticipated adverse device effects. The mean overall SNOT 20 score at baseline was 2.9 ∓ 1.0. Mean overall SNOT 20 scores at 1-week, 3-month, and 6-month follow-up were 0.8 ∓ 0.8, 0.7 ∓ 0.8, and 0.8 ∓ 0.9 respectively. Patency at 3-months as confirmed by CT imaging was 95.8%. Conclusion These results indicate that transantral balloon dilation of the ostiomeatal complex under local anesthesia appears to be a safe technique for managing isolated maxillary or maxillary and anterior ethmoid sinusitis and can potentially be performed safely in an office setting.

Abstract:

The modern diagnostic radiology department is equipped with a variety of medical imaging systems that can be used for evaluation of diseases of the sinonasal cavities. Each has advantages and disadvantages. The imaging examinations of the paranasal sinuses may include conventional films, complex motion tomography, computed tomography (CT) and magnetic resonance imaging (MRI). The indications for these imaging methods are reviewed, along with a discussion on the role of imaging for endoscopic sinus surgery. A summary of CT anatomy relating to the ethmoidal sinuses and ostiomeatal complex is given, as is a review of the risk of radiation for radiologic sinus imaging.

Abstract:

Abstract BACKGROUND. There are not many works devoted to the structures of a nasal cavity in odontogenic maxillary sinusitis and to a condition of an alveolar ridge of the maxilla with a rhinogenous genesis of the disease. MATERIAL AND METHODS. 100 patients (N) with chronic sinusitis hospitalized at the ENT (N=50) and Oral and Maxillofacial Surgery (N=50) Departments were examined. The character of anatomic options of a nasal septum in chronic maxillary sinusitis is estimated according to a cone-beam computed tomography (CBCT) with use of our own developed scheme of coordinates in the form of “triangles” which allows establishing versions of the block of the ostiomeatal complex and nasal septum deviation. RESULTS. In cases of rhinogenous and odontogenic causes of maxillary sinusitis, the triangle deviation is detected more often, including a perpendicular plate of the ethmoid bone, the vomer and the quadrangular cartilage, contributing to the block of the ostiomeatal complex. This scheme has allowed us to establish a group of patients with the mixed genesis of maxillary sinusitis in the Otorhinolaryngology and MFS Departments (36% and 42% respectively) and that, in its turn, requires a cross-disciplinary approach when choosing a strategy of treatment. CONCLUSION. In case of rhinogenous genesis of the disease, the bilateral nature of the process with involvement of other paranasal sinuses in the inflammatory process is detected more often. The category of patients with mixed genesis (rhinogenous plus odontogenic) of sinusitis demands a cross-disciplinary approach to diagnosis and making a decision about treatment strategies.

Abstract:

Silent sinus syndrome refers to a constellation of spontaneous and progressive enophthalmos and hypoglobus in the setting of asymptomatic ipsilateral maxillary sinus atelectasis. Although its exact etiopathogenesis is not completely understood, obstruction of the ostiomeatal complex appears to be the inciting event. Most of the reported cases of silent sinus syndrome involve one maxillary sinus. Only a handful of true bilateral silent sinus syndrome cases have been reported in the literature. The aim of this report is to present a case of metachronous bilateral maxillary silent sinus syndrome and its natural progression. Also included is a review of the literature on ethmoidal, frontal, and bilateral maxillary silent sinus syndrome.

Abstract:

The ostiomeatal complex has been identified as an important anatomic region in the pathogenesis of sinusitis. Functional endoscopic techniques rely on removal of mucosal disease from this site to improve drainage and aeration. Structural variations and the use of a sharp blade to create the infundibulotomy can result in inadvertent injury to the orbit. To avoid orbital penetration we perform the infundibulotomy with a curved, blunt dental elevator and displace the uncinate with its medial and lateral mucosa toward the middle turbinate. This stretches the infundibulum to reveal the maxillary ostium at its depth. The remaining mucosal attachments of the uncinate process are then incised under direct vision, and the complex is resected, creating an initial wide antrostomy. This technique has avoided orbital penetration in 700 cases in patients with early or late stages of mucosal disease.

Abstract:

The increasing popularity of fiberoptic endonasal sinus surgery has led some to state that a Caldwell-Luc procedure should be performed only to manage tumors involving the maxillary sinus and epistaxis, a procedure that requires exposure of the pterygopalatine fossa for vessel ligation. However, a modern version of the Caldwell-Luc procedure should be considered in instances where failure of endoscopically-controlled endonasal sinus surgery (coupled with appropriate medical management) occurs because of the presence of severely or diffusely diseased or damaged mucosa. This approach is also suggested for suspected fungal sinusitis extensively involving the antrum, for all reoperations for isolated antral disease in which the ostiomeatal complex and ethmoids are clear, and for closure of oro-antral fistulas associated with marked inferior antral mucosal disease.

Abstract:

AbstractWhilst clinical success of endoscopic surgery for chronic rhinosinusitis has necessarily depended primarily upon subjective evaluation, a range of objective techniques are now available which may facilitate our interpretation of results. A group of 200 patients underwent assessment of symptoms by sequential visual analogue scoring, olfaction by qualitative and quantitative testing, nasal airflow by forced inspiratory peak flow, anterior rhinomanometry, nasomucociliary function by ciliary beat frequency and nasal topography by acoustic rhinometry performed pre- and post-operatively. Significant improvement was demonstrated in all symptoms examined, olfactory tests and ciliary beat frequency whilst acoustic rhinometry provided an attempt to quantify the surgical cavities. These results offer an interesting perspective on the pathology of rhinosinusitis and the rationale for surgery within the ostiomeatal complex.

Abstract:

The primary goal of sinusitis management is resolution of infection, leading to patency of the ostiomeatal complex. Antibiotics and decongestants are the cornerstones of therapy for acute sinusitis. Diagnosis of acute sinusitis is based on the history and physical findings. Sinusitis is considered to be acute or recurrent acute if infection resolves without residual mucosal damage. Choices for first-line antibiotic therapy include adequate dosages of trimethoprim-sulfamethoxazole, loracarbef, and amoxicillin-clavulanate. Decongestants and mucoevacuants may reduce tissue edema, facilitate drainage, and maintain ostial patency. Topical corticosteroids are useful additional therapy in allergic rhinosinusitis and as an aid in the long-term management of chronic sinusitis. Parenteral corticosteroids have no role in first-line management of acute or recurrent acute sinusitis.

Abstract:

The occurrence of foreign bodies in paranasal sinuses is extremely rare. The symptoms are vague and usually discovered after extra/intracranial complications. They may, therefore, go unnoticed if there isn’t a strong clinical suspicion. We present a clinical case of a 64-year-old woman with a paranasal sinus microsurgery history more than 30 years ago, who presented with headache and purulent rhinorrhea. A glass tubular structure was discovered in the ethmoid complex. She underwent functional endoscopic sinus surgery. Since glass is an inert material that doesn’t cause foreign body reaction, the patient may not present any symptom or sign. However, if there is obstruction in the drainage of the ostiomeatal complex, it can manifest itself as rhinosinusitis, which we believe happened in our case. To the best of our knowledge, this is probably the first reported case of a glass removed from the ethmoidal sinuses, diagnosed with more than 30 years of evolution.

Abstract:

In current theories of sinusitis, obstruction at the ostiomeatal complex leads to localized inflammation and infection. Haller cells, an extension of ethmoid pneumatization along the maxillary antrum roof, have also been suggested as a causative factor in sinusitis because of their ability to cause narrowing of the infundibulum. Coronal CT scans were reviewed in 154 patients to evaluate the role of Haller cells in sinusitis. Haller cells were present in 34% of patients. The cells were graded as small, medium, or large, and correlated with radiologic evidence of sinusitis (e.g., mucosal thickening or opacification). A statistically significant increase in maxillary sinus mucosal disease was noted in patients with medium or large Haller cells (45.8%) versus those with small cells (28.9%, p < 0.05). Thus obstructive medium and large Haller cells may be an etiologic factor in sinusitis.
