<p class="abstract"><strong>Background:</strong> Chronic rhinosinusitis is one of the common problems in ENT Department which can be caused due to infections or anatomical blockage or allergy. We performed this study to assess the cause, clinical features and the effect of treatment on rhinosinusitis.</p><p class="abstract"><strong>Methods:</strong> 60 patients of chronic sinusitis with symptoms persisting beyond three months, Nasal Endoscopic findings with Polyps/Discharge/edematous mucosa were included in the study. A detailed clinical history, with complete Ear, Nose, Throat, and Head and Neck examination, blood tests like complete blood picture, Blood sugar levels, ESR and Hepatitis profile. X ray of paranasal sinuses, (water’s view) and lateral view, Chest x-ray –PA View and CT scan of paranasal sinuses (axial and coronal section with 3mm cuts at OMC) was done for all patients. Diagnostic Nasal Endoscopic examination (DNE) for detection of polyps / discharge / edematous mucosa in middle meatus was also done for the patients where it was necessary. The patients were given medical or surgical treatment according to the symptom and followup was done for 3 months for all patients.  </p><p class="abstract"><strong>Results:</strong> Over 75% of the patients had incidence of sinusitis in the age group of 16 – 45 years. The most common etiology was sinusitis caused by infections (26 – 44%) followed by anatomical obstruction (22 – 36%). Of the 22 anatomical obstruction the most common was Deviated nasal septum in 14 (62%) of the cases followed by 4 (19%) CB, 3 (15%) pradixical MT and 1 (4%) prominent aggernasi. The most common sign and symptom was headache and polypoidal changes observed in 36 patients each (60%), followed by nasal obstruction in 35 patients (50%). 12 (20%) of the patients were treated with polypectomy + FESS while 14 (23%) of them were treated with septoplasty + FESS. 34 (57%) were treated with only FESS.</p><strong>Conclusions:</strong> Chronic sinusitis doesnot affect a particular age or sex and is more common among patietns with an upper respiratory tract infection. CT scan of the paranasal sinuses is the most useful tool in diagnosing the disease and FESS is the treatment of choice.

<p class="abstract">Sinonasal diseases are serious health issues found in the clinical practice. Sinonasal diseases are often associated with anatomical variants in the sinonasal tract. There are numerous sinonasal anatomical variants found frequently in computed tomography (CT) scans of the paranasal sinuses. Middle turbinate concha bullosa is a common anatomical variant found in the nasal cavity. Pneumatization of the middle turbinate is called as concha bullosa. The pneumatization of the middle turbinate is mostly via the anterior ethmoidal air cells. Pneumatizations through posterior ethmoid air cells are also reported. There are three types of concha bullosa such as lamellar, bulbous and extensive.  Majority of the patients with middle turbinate concha bullosa are asymptomatic. Sometimes this is accidentally detected during proper evaluation of the headache. Sometimes the middle turbinate concha bullosa is associated with chronic sinusitis. However, there are very few literatures which correlate the middle turbinate concha bullosa and chronic sinusitis. Although chronic sinusitis is a clinical diagnosis, the imagings like CT scan are useful to assess the extent of the disease and demonstrate the sinonasal anatomy. CT scan of the paranasal sinuses and diagnostic nasal endoscopy are important tests useful for evaluation of the middle turbinate concha bullosa and its relations with chronic sinusitis. This review article discusses on the details of the middle turbinate concha bullosa and its relationship with chronic sinusitis.</p>

This case is related to a 52-year-old lady with proptosis, diplopia and diminution of vision due to a mass lesion in upper medial quadrant of the orbit. CT scan revealed a well defined mass in basi-frontal area with intra-orbital and intracranial extension. On exploring it was found to be mucopyocele of the frontal sinus. Surgical excision was done by external approach. The symptoms and signs resolved completely within a week. Frontal sinus mucopyoceles are benign and curable. Early recognition and management of them is of paramount importance because they can expand and cause local, orbital or intracranial complications.

The aim of the study was to identify possible changes in the maxillary sinuses during new coronavirus infection in comparison with the changes in the sinuses occurring during acute respiratory infections and to correlate the gender structure of the study groups. Material and methods. The study included 40 patients (18 women and 22 men) with a confirmed new coronavirus infection, hospitalized at the Covid Hospital Clinics of Samara State Medical University in 2020. All patients underwent multispiral computed tomography of the paranasal sinuses on a Ge revolution Evo 128 tomograph on the 10th day after the appearance of the first clinical symptoms. We also examined a control group of patients with acute respiratory infections with similar complaints of impaired sense of smell, rhinorrhea, and upper maxillary sinus discomfort. This group also included 40 people (24 women and 16 men). Statistical processing of the study results was performed using Microsoft Excel software package, the Mann – Whitney method of statistical significance calculation was used. Results and discussions. In 18 (45%) patients with a confirmed new coronavirus infection, a slight mucosal thickening along the lower wall of the maxillary sinuses was found symmetrically on both sides. Six (15%) of them were women and 12 (30%) were men. The age of the examined patients ranged from 31 to 83 years. Chronic sinusitis was noted in the history of 8 (20%) of the examined patients. In 6 (15%) patients with chronic sinusitis no abnormalities were detected in the maxillary sinuses at the time of examination. Two of them had parietal thickening of the mucous membrane along the lower wall of the maxillary sinuses. In the control group, there was significant symmetric parietal thickening of the mucous membrane of the paranasal sinuses in 24 (60%) examined patients (14 women and 10 men). There were no statistically significant differences in the prevalence of changes in the studied and control groups. Conclusion. According to the results of this study, there were no data on the pattern of occurrence of changes in the mucosa of the maxillary sinuses in new coronavirus infection with gender background or the presence of chronic inflammation of the maxillary sinuses in the history compared with the control group of examined patients after acute respiratory infections.

Purpose: to identify patterns in the prevalence of various clinical forms of chronic sinusitis (exudative, proliferative, alterative) depending on the clinical and immunological stages of HIV infection. The study involved 108 HIV-infected patients who were diagnosed with chronic sinusitis. The prevalence of each of the clinical forms of chronic inflammation of the paranasal sinuses (exudative, proliferative, alterative) at different immunological and clinical stages of HIV infection was determined. The majority of HIV-infected persons with chronic sinusitis were diagnosed with a proliferative form of inflammation of the paranasal sinuses (61.1 ± 4.7). As the clinical stage of HIV infection progressed (WHO classification), a decrease in the prevalence of exudative forms of chronic sinusitis (from 84.8 ± 6.2 at the first stage to 4.0 ± 3.9 at the fourth) and, accordingly, an increase in proliferative forms (with 15.2 ± 6.2 at the first stage to 92.0 ± 5.4 at the fourth). As the number of CD4-lymphocytes in the blood of HIV-infected patients decreased, a significant decrease in the frequency of detection of exudative forms of chronic sinusitis was observed (from 85.0 ± 8.0 with a CD4-lymphocyte level of more than 500 uL-1 to 12.9 ± 4.3 with the level of CD4 lymphocytes is less than 200 uL-1) and, accordingly, an increase in the prevalence of proliferative forms of chronic inflammation of the paranasal sinuses (from 15.0 ± 8.0 to 83.9 ± 4.7, respectively). As immunological deficiency progresses in HIV-infected patients, the prevalence of proliferative forms of chronic inflammation of the paranasal sinuses increases, which is a factor determining the tactics of treating chronic sinusitis in this group of patients.

Introduction: The variation in the course of infraorbital canal and protrusion of the infraorbital nerve through it to the maxillary sinus may lead to its accidental injury during reconstructive or endoscopic sinus surgery. Preoperative identification of this variant will prevent unintended injuries. Methods: A retrospective study of 307 patients who underwent CT scan study of the paranasal sinuses at Chitwan Medical College, Nepal was conducted. The protrusion of infraorbital nerve to the maxillary sinus was identified and the length of the bony septum along with the infraorbital nerve was measured. It was further classified as Class I to III according to the length of the septum.Results: The prevalence of protrusion of inferior orbital nerve in our study was 11.40 % and bilateral protrusion was 5.8 %.  The median length of the protruding component along with the septum was 4.9 mm. Conclusion: Preoperative identification of the normal protrusion of infraorbital nerve to the maxillary sinus will prevent accidental injuries during sinus surgery. CT scan of the paranasal sinus would be the modality of choice for identification of this variant.
