Abstract:

Background Nasal polyps accompany eosinophilic chronic rhinosinusitis (ECRS). Cytokines, including interleukin (IL)-25, IL-33, and thymic stromal lymphopoietin (TSLP) expressed in nasal mucosa have been implicated in polyp pathogenesis. We investigated the role of nasal polyp epithelium cytokine expression in eosinophilic infiltration in ECRS. Methods Tissues were collected from 39 patients undergoing nasal surgery. Cases were divided into 3 groups: control (CTR), non-ECRS (nECRS), and ECRS and were evaluated for IL-25, IL-33, and TSLP expression. Results Abundant eosinophilia was observed underneath the nasal mucosa and around the nasal ducts in polyps in ECRS and correlated positively with IL-33 protein expression. Conclusion Cytokine expression in nasal duct cells and eosinophilic infiltration around duct cells similar to those in the nasal mucosa occurred in the nasal epithelium of polyps, suggesting its role in inducing eosinophilic inflammation.

Abstract:

AbstractBackground:Most patients with nasolacrimal duct obstruction have dry, crusty nasal mucosa. Mucociliary clearance is modulated by the amount and biochemical composition of nasal mucus. Nasolacrimal duct obstruction disturbs the drainage of tears into the nasal cavity.Objective:We examined the effect of nasolacrimal duct obstruction on the mucociliary transport of nasal mucosa, by comparing saccharine test results for epiphora patients versus healthy volunteers.Study design:Prospective, randomised, clinical trial.Methods:Eight patients with bilateral epiphora and 10 patients with unilateral epiphora were included in the study group. Complete nasolacrimal duct obstruction was demonstrated by studying irrigation of the nasolacrimal system, and by fluorescein dye study. The control group comprised 20 healthy volunteers. Mucociliary transport was assessed by the saccharine test in both the study and control groups. The saccharine transit times of 26 impaired nasal cavities were compared with those of 20 healthy nasal cavities of controls. Also, the saccharine transit times of the healthy nasal cavities of the 10 patients with unilateral epiphora were compared with those of their diseased sides, and also with those of healthy volunteers.Results:The saccharine transit times of the epiphora patients were statistically significantly greater than those of the control group. Also, there was a statistically significant difference in saccharine transit times, comparing the healthy and impaired nasal cavities of patients with unilateral epiphora.Conclusion:Nasolacrimal duct obstruction has a negative effect on nasal mucociliary clearance. This may be related to changes in the amount and biochemical composition of nasal mucus.

Abstract:

Abstract Nasolacrimal duct obstruction (NLDO) is a common event in clinical practice. The authors, all members of the Italian Society of Rhinology, analysed 100 cases from different ENT Departments. The causes of NLDO, according to the etiology, can be divided into two classes: idiopathic primary acquired nasolacrimal duct obstruction and secondary. The aim of the study was to describe an association between the sign and symptoms of chronic rhinosinusitis and a complaint of epiphora.

Abstract:

Objective Epiphora can result from obstruction anywhere along the nasolacrimal (NL) system. The inferior meatus (IM) is not routinely evaluated despite the ease of nasal endoscopy. We propose the IM pathology is common in patients with epiphora, and surgery can be directed at the IM. Methods Consecutive patients referred for epiphora between July 2006 and July 2007 underwent endoscopic evaluation of the IM. All patients then underwent intervention to address the NL duct orifice obstruction. Results There were 14 patients, 11 females, mean age 53 years. Four patients had bilateral epiphora, for 18 total lacrimal systems. Two patients were treated in clinic, one for a dacryolith and one, a thick mucoid plug. At the time of surgery, 4 NL duct orifices were obstructed by a cyst. The remaining 12 nasolacrimal ducts were obstructed by hypertrophied mucosa. In 4, hypertrophic mucosa was found proximal to Hasner's valve, and 3 of these had early recurrent symptoms requiring revision (2 DCR's). 13 of 14 sides with pathology at Hasner's valve had resolution or dramatic improvement with patent NL ducts with inferior meatal treatment alone. Mean follow-up was 5 months. Conclusions Routine endoscopic evaluation of the inferior meatus in epiphora uniformly identified pathology at the NL duct orifice. At the time of surgery, identification of pathology at the NL duct orifice and distal NL duct portends a better outcome with endoscopic treatment of the IM, whereas identification of proximal NL duct obstruction had a poorer outcome with treatment through the IM.

Abstract:

Objective: A nasal septal abscess after placement of a dental implant is seldom seen and is usually caused by an infection around the implant. A septal haematoma following dental implantation leading to septal abscess formation has never been reported. Methods and results: We present a case of a patient who developed a septal abscess after dental implantation without accompanying signs of infection around the implant. On the computed tomography scan we found the implant protruding the nasopalatine duct which led to bilateral septal hemorrhage, resulting in abscess formation. The patient underwent reconstructive nasal septum surgery, using an autologous auricular cartilage graft. This resulted in a good nasal function and cosmetic outcome. Conclusions: Medical health care professionals should be aware of a septal abscess in case of an acute blocked nose even without prior nasal or facial trauma or nasal surgery. Reconstruction of the septal nasal cartilage using autologous conchal cartilage is a good solution to preserve nasal function as well as tip support.

Abstract:

AbstractTraversodontidae is a group of Triassic herbivorous/omnivorous cynodonts that represents the most diversified lineage within Cynognathia. In southern Brazil, a rich fossil record of late Middle/mid-Late Triassic cynodonts has been documented, with Exaeretodon riograndensis Abdala, Barberena, and Dornelles, 2002 and Siriusgnathus niemeyerorum Pavanatto et al., 2018 representing two abundant and well-documented traversodontids. The present study provides a comparative analysis of the morphology of the nasal cavity, nasal recesses, nasolacrimal duct, and maxillary canals of both species using computed tomography, highlighting the changes that occurred in parallel to the origin of mammaliaforms. Our results show that there were no ossified turbinals or a cribriform plate delimiting the posterior end of the nasal cavity, suggesting these structures were probably cartilaginous as in nonmammaliaform cynodonts. Both species show lateral ridges on the internal surface of the roof of the nasal cavity, but the median ridge for the attachment of a nasal septum is absent. Exaeretodon riograndensis and S. niemeyerorum show recesses on the dorsal region of the nasal cavity, which increase the volume of the nasal cavity, potentially enhancing the olfactory chamber and contributing to the sense of smell. On the lateral sides of the nasal cavity, the analyzed taxa show a well-developed maxillary recess. Although E. riograndensis and S. niemeyerorum have roughly similar nasal cavities, in the former taxon, the space between the left and right dorsal recesses of the nasal cavity is uniform along its entire extension, whereas this space narrows posteriorly in S. niemeyerorum. Finally, the nasolacrimal duct of S. niemeyerorum is more inclined anteroposteriorly than in E. riograndensis.

Abstract:

Background: Primary acquired nasolacrimal duct obstruction (PANDO) is a common entity with associated different types of intranasal abnormalities. The pathogenesis of PANDO is unknown. The objective of the study was to describe the intranasal findings in cases of PANDO and find out any association of these findings to the disease.  Methods: A comparative cross-sectional study was designed consisting of 50 cases of unilateral PANDO with epiphora and 50 normal volunteers with no history of epiphora. Nasal Evaluation was done with anterior rhinoscopy and nasal endoscopy. Data was tabulated and analyzed using SPSS version 21.  Results: The mean age in the unilateral PANDO group was 33.6 years and 34.5 years in the normal volunteer’s group (P-0.84). Left sided dominance of PANDO was observed in 64% (32/50) cases. The odds of having Nasolacrimal duct (NLD) obstruction was1.6 times more among individuals having septal deviation versus no deviation (95% CI, 0.907–2.78). The laterality of septal deviation was corresponding to the side of NLD obstruction in 91% (31/34) cases. High located DNS was more common in the PANDO group which was significant (P-value 0.012). Turbinate hypertrophy, the presence of septal spur or rhinitis had no significant association with NLD obstruction.  Conclusions: Deviated nasal septum (DNS), turbinate hypertrophy, septal spur and rhinitis were the associated intranasal findings in cases of unilateral PANDO. A significant association exists between DNS and PANDO, although a cause and effect relation require further probing.

Abstract:

Purpose. To evaluate effectiveness of nasolacrimal duct intubation with silicone tube in congenital dacryocystitis (CD) and substantiate optimal timing of its removal. Material and Methods. 25 patients with CD were operated in the Khabarovsk branch of the S. Fyodorov Eye Microsurgery Federal State Institution in order to restoring conductivity of nasolacrimal duct of using the intubation set FCI (France). In addition to ophthalmic examination methods, all children underwent scleral examination which includes determination of acid base state (pH) of the wound exudate (secretion) from the nasal cavity. Inflammatory index was also scored which characterized the severity of standard signs of inflammation in the nasal mucosa after surgery. Results. There were no complications during the surgery. Normalization of nasal exudate pH values in children with uncomplicated СD was registered by the 4th week after the surgery. Normalization of nasal exudate pH values in children with recurrent СD was registered by the 6th week, coinciding with full disappearance clinical signs of inflammation. At the indicated periods, the silastic tubes were removed. One child had relapse of disease after suffering acute rhinitis 6 months after the surgery. This patient underwent dacryocystorhinostomy with positive effect. Conclusion. Bicanalicular temporary intubation of nasolacrimal duct using silicone tube in children with CD is considered as an effective treatment. In accordance with obtained results, in children with uncomplicated CD the removal of silicone implant is advisable 4 weeks after its installation, in children with recurrent CD the removal of silicone implant is advisable no earlier than 6 weeks. Key words: congenital dacryostenosis, intubation set, endoscopic rhinoscopy.

Abstract:

In several mammals, a direct connection between the nasal cavity and the oral cavity is a common finding. The structure is named the nasopalatine duct (NPD). It has been hypothesized to be functional in terms of transportation of odorants from the oral cavity to the nasal cavity. In humans, the NPD exists during embryological development. The connection between the nasopalatine infundibulum and the incisive fossa is typically closed at the time of birth. We present the case of a 24-year-old man who presented with a persistent NPD. By means of a thin, soft tube, it was possible to probe the NPD. Magnetic resonance imaging revealed a bony gap between the hard palate and the alveolar process of the maxillary bone with a length of 16 mm and a width of 6 mm. In light of the literature of the past 500 years, this represents a rare finding of a persistent NPD.

AbstractBackgroundSubmucosal diathermy to the inferior turbinate is a widely practised procedure to improve the nasal airway when nasal obstruction is due to hypertrophy of the inferior turbinate. This paper reports a case of an unusual nasolacrimal complication following submucosal diathermy to the inferior turbinate, and reviews the relevant literature.Case reportA 33-year-old male patient developed a patulous nasolacrimal duct opening following submucosal diathermy of the inferior turbinate. This resulted in spontaneous reflux of air and nasal mucus on to the ocular surface.ConclusionThis newly recognised complication of submucosal diathermy to the inferior turbinate indicates the need to be aware of the potential risk to the nasolacrimal system with this technique.

Abstract:

Endonasal endoscopic dacryocystorhinostomy (EES-DCR) has gradually become the main surgical method for treating chronic dacryocystitis. Whether the placement of the lacrimal drainage tube during the operation can improve the operation’s success rate is an issue. This study observes the effect of an indwelling lacrimal drainage tube on the curative effect of EES-DCR in patients with chronic dacryocystitis. The cure rate of the Lacrimal duct drainage tube non-indwelling group A was 93.8% (46/49). The 3 cases failed because of the nasal cavity’s inflammation, which resulted in the adhesion of the anastomotic stoma and the middle turbinate. The cure rate of the Lacrimal drainage tube indwelling group B was 85.7% (42/49). The 7 cases failed because of the excessive proliferation of the tissue around the anastomosis, the hyperplasia of granulation tissue, the shedding of the lacrimal duct drainage tube, the crack of the lacrimal duct, and the premature removal of the lacrimal duct drainage tube caused the contraction of the mucosa around the anastomosis, resulting in the anastomosis obstruction. There was no obvious difference between the two groups (P > 0.05). At 6 months, 46 cases of the EES-DCR group A had gradually epithelialized anastomoses without granulation tissue growth with the follow up time extension. In the EES-DCR group B, 42 cases of anastomoses were gradually epithelialized without granulation tissue growth. Nasal endoscopic dacryocystorhinostomy combined with an indwelling lacrimal duct drainage tube can be used to treat chronic dacryocystitis, but an indwelling lacrimal duct drainage tube has no significant effect on the efficacy of chronic dacryocystitis.

Abstract:

Nasoalveolar cysts, which originate from epithelial remnants of nasolacrimal duct, are nonodontogenic soft tissue lesions of the upper jaw. These cysts are thought to be developmental and are presented with fullness in the upper lip and nose, swelling on the palate, and sometimes nasal obstruction. Because of cosmetic problems, they are often diagnosed at an early stage. These lesions are mostly revealed unilaterally but also can be seen on both sides. In this case report, a patient who complained of nasal obstruction and then diagnosed with bilateral nasoalveolar cysts and treated by sublabial excision is presented and clinical features and treatment approaches are discussed with the review of literature.

Abstract:

Dacryocystorhinostomy (DCR) is the preferred treatment for lacrimal duct blockage. Endoscopic DCR has been practised increasingly in recent years as it avoids a facial scar and can be performed as a day procedure. Recent improvements in endonasal surgical techniqueled to success rates of up to 90per cent. However, the endonasal approach often requires septalor turbinate surgery to optimze access to the lacrimal area.The incidence of concomitant procedures was investigated in 256 patients undergoing endonasal nonlaser DCR. In this study 55 out of 256 patients (21.5 per cent) required additional endonasal procedures to improve access to the lacrimal area.It is therefore advisable that otolaryngologists are involved in this procedure.

Abstract:

A 3-year-old, castrated male golden retriever was presented for evaluation of recurrent ocular discharge of 4 months’ duration from the left eye. Dacryocystorhinography was performed and demarcated a cystic dilatation of the left nasolacrimal duct with obstruction of the duct distal to the cystic cavity. Surgical exploration of the left maxillary sinus was performed to confirm the diagnosis and reestablish drainage into the nasal cavity. Recovery was uneventful, and the dog has been asymptomatic for &gt;36 months postoperatively. This report documents the third published case of surgical treatment for cystic dilatation of the nasolacrimal duct.

Abstract:

We analyzed the internal structure of the nasal cavities of hawksbill, olive ridley and black sea turtles from computed tomography images. The nasal cavities of all three species consisted of a vestibule, nasopharyngeal duct and cavum nasi proprium that included anterodorsal, posterodorsal and anteroventral diverticula, and a small posteroventral salience formed by a fossa of the wall. These findings were similar to those of green and loggerhead sea turtles (Cheloniidae), but differed from those of leatherback sea turtles (Dermochelyidae). Compared to the Cheloniidae species, the nasal cavity in leatherback sea turtles was relatively shorter, wider and larger in volume. Those structural features of the nasal cavity of leatherback sea turtles might help to suppress heat dissipation and reduce water pressure within the nasal cavity in cold and deep waters.

Abstract:

AbstractWe present an extremely rare case of epithelial-myoepithelial carcinoma (EMC) arising in the nasal cavity. The patient was a 56-year-old Japanese male with a polypoid tumour arising from the nasal septum. Histopathological examination revealed the tumour to consist of a solid proliferation of clear-cells and, in some areas, small or elongated duct structures with a double-layered arrangement of inner cuboidal cells and outer clear-cells. Dual differentiation toward myoepithelial and ductal cells were confirmed immunohistochemically. The occurrence of EMC in the nasal cavity is possible and this entity should be generally recognized by surgical pathologists, not only those engaged in head and neck surgery.

Abstract:

Secondary acquired nasolacrimal duct obstruction after radioiodine therapy is a comparatively rare complication but it requires treatment at an early stage. The symptoms of secondary acquired nasolacrimal duct obstruction are tearing, eye redness, discharge at ocular surface, a mass growing at lacrimal sac site. The considered complication occurs after radioiodine therapy in dose of 150 mCi, the rate of occurrence is dose-dependent. There are no clinical guidelines for preventing this complication but there are reports of nasolacrimal duct preventive intubation and those about developing new drug agents that block an action of the protein that uptakes iodine in the nasolacrimal duct mucosa. For diagnosing, special diagnostic procedures and an ophthalmologist consultation are required. For the correction of this complication, conservative treatment (with low efficacy) and special surgical treatment are used, including nasolacrimal duct recanalization with different techniques and anastomosis between nasolacrimal duct and nasal cavity formation. In cases of early patient encounter, it is possible to use more functional and less invasive surgical techniques, in cases of late encounter, more invasive surgical techniques are used.

Abstract:

AbstractObjective:To determine the success rate of initial probing in children with congenital nasolacrimal duct obstruction at different ages, using nasal endoscopy.Methods:Fifty eyes of 38 consecutive children with congenital nasolacrimal duct obstruction underwent endoscopic nasolacrimal duct probing under general anaesthesia. Patients were followed up for at least three months. Probing success was defined as complete remission of symptoms and a normal fluorescein dye disappearance test result.Results:The age range of patients was 17–109 months. The success rates of probing were: 100 per cent (29 out of 29) for cases of stenosis at the lower nasolacrimal duct, 100 per cent (7 out of 7) for functional epiphora cases and 92.86 per cent (13 out of 14) for nasolacrimal atresia cases. Overall, there was only one child for whom the probing treatment for nasolacrimal duct obstruction was not successful; this child had Down's syndrome and a more complex developmental abnormality of the nasolacrimal duct. Age and site of obstruction were not found to significantly affect the outcome of probing.Conclusion:Probing of the nasolacrimal system using an endoscopic approach allows direct visualisation of the nasolacrimal duct. This can facilitate diagnosis of the anomaly and significantly increase the procedure success rate.

Abstract:

Background Nasolacrimal duct obstruction, secondary to inflammation of the nasal mucosa, can result in epiphora. This can be treated successfully with topical corticosteroids, avoiding the need for surgery. This study tests the hypothesis that treating clinically significant rhinitis improves the symptoms of epiphora. Methods A randomized controlled crossover trial (pilot study) was performed at the Cumberland Infirmary, Carlisle. Patients were assessed in an epiphora clinic by a consultant ophthalmologist and were included in the trial if they had bilateral functional epiphora, i.e., the nasolacrimal duct was patent on syringing. Twenty-three patients were then referred to a consultant otolaryngologist, where the severity of rhinitis and epiphora were assessed using visual analogue scales, subjective scoring, and clinical assessment. The 11 patients suitable for the study were randomized into two groups. The treatment group received nasal corticosteroids and the control group received no treatment, both groups changing treatment arms at a specified point. Subjective and objective scores were assessed at the beginning, midpoint, and end of each treatment period. Results Seven of 11 patients showed an improvement in epiphora scores with topical therapy. Six patients documented a symptomatic improvement. Eight patients showed an improvement in symptoms and signs of rhinitis, with two patients continuing on nasal corticosteroids for nasal symptoms only. There was a statistically significant improvement in both epiphora symptom scores and clinical findings of rhinitis in patients treated with nasal steroids (p = 0.021 and 0.019, respectively). Conclusion Epiphora secondary to rhinitis can be treated successfully with intranasal steroids. Patients with epiphora should be asked about symptoms of rhinitis and should always have their nose examined for evidence of intranasal pathology.

AbstractObjective:To evaluate the results of endoscopic dacryocystorhinostomy performed to treat acquired nasolacrimal duct obstruction.Design:Retrospective analysis of the outcome of endoscopic dacryocystorhinostomy performed in the conventional manner (i.e. without power instruments or laser) to treat acquired nasolacrimal duct obstruction.Subjects:Outcomes for 300 patients with acquired nasolacrimal duct obstruction were evaluated. Cases with congenital or traumatic blockages were excluded. All the cases were evaluated for nasolacrimal duct blockage by the syringing and regurgitation test. Surgery was performed under local anaesthesia with sedation. Follow up was conducted by syringing and nasal endoscopy, up to one year. Results were compared with published data for endoscopic and external dacryocystorhinostomy.Results:Outcomes were evaluated subjectively using patient symptoms, syringing results and endoscopic appearance. All cases were symptom-free following endoscopic dacryocystorhinostomy. Revision surgery was performed in 18 cases. Stents were placed in 10 patients, of which two developed granulations. Septoplasty was performed in 25 cases to gain access to the lacrimal sac area.Conclusion:The results were comparable with published data for endoscopic and external dacryocystorhinostomy.

Abstract:

Pathology of the vertical section of the lacrimal duct continues to attract the interest of otorhinolaryngologists and ophthalmologists. With the development of new technologies, an active search began for effective and safe methods of conservative and surgical treatment of the disease of the lacrimal organs. Measures aimed at preventing scarring: various drains, differing in shape, material, method of conduction, and duration of stay in the lacrimal ducts, medical methods can not only contribute to recovery, but also extend the time and negatively affect the outcome of treatment. The problem of scarring formed dacryorrhinostomy remains unresolved to this point. The article presents the results of the examination of patients with pathology of the vertical division of the lacrimal duct after video endoscopic endonasal dacryocystorhinostomy performed in the ENT department of the Clinics of Samara State Medical University. In all patients, the stoma of 0,7–0,8 сm is formed endonasally. The data of the video endoscopic examination of the nasal cavity and lacrimal ducts after the use of stents and the preparation Antiadgesin were analyzed. Patients are divided into 2 groups. Group 1 – 17 people who, after the formation of dacryorhinostomy, used bicanalicular silicone stents that were in the lumen of the lacrimal duct for 2 to 4 weeks, group 2 – 12 people who after the formation of the dacryorrhinostomy injected the drug „Antiadhesin“ into the lacrimal duct through the upper and lower tear points with blunt cannula in the amount of 1 ml. The effectiveness of prophylactic measures aimed at eliminating stenosis of the dacryorhinostomy was evaluated. Data on the greater efficiency of surgical intervention in patients in group 2 with the use of the drug Antiadgesin compared with group 1 using stents.
