<p class="abstract">Anatomic variations of the paranasal sinuses can lead to various diseases per se. The paranasal sinus anatomy should be carefully examined prior to performing endoscopic sinus surgery in terms of both existent pathologies and anatomic variations. The anatomy of the paranasal sinuses and its variations have gained importance, along with advances in coronal paranasal sinus computed tomography and extensive use of endoscopic sinus surgery. Rhinolith is a mass resulting from calcification of an endogenous or exogenous nidus within the nasal cavity. It is an uncommon disease that may present asymptomatically or cause symptoms like headache and nasal obstruction. A 24 year old woman was admitted in ENT department of GGS Medical College and Hospital, Faridkot with complaints of nasal obstruction, anosmia and headache persisting for 5 years. Right sided rhinolith was detected on anterior rhinoscopy. Bilateral concha bullosa with right sided rhinolith was reported on preoperative paranasal computed tomography scan. It is known that the paranasal sinuses have a number of anatomical variations. Sometimes severe anatomic variations predispose to rhinosinusitis. Herein we report a rare case, along with a review of the literature, to emphasize that severe anatomical variations should not be ignored.</p>

ABSTRACT A prospective study was conducted on 50 patients at the SGRD Institute of Medical Sciences and Research, Amritsar, suffering from paranasal sinus disease correlating the findings of computed tomography (CT) using Siemens SOMATOM Emotion 6 slice CT machine with diagnostic nasal endoscopy or functional endoscopic sinus surgery (FESS). Infection of the paranasal sinuses is very common. Surgical clearance of these chronically infected sinuses while maintaining their ventilation and drainage is the treatment of choice. To achieve this goal, there should be some diagnostic modality that guides us toward the exact diagnosis and safe intervention. Computed tomography proves to be the most reliable method of preoperative assessment of patients undergoing FESS as it delineates the extent of the disease and defines any anatomical variants and relationship of the sinuses with the surrounding important structures, thus providing a road map for sinus surgery. In our study, most patients were in the 3rd and 4th decades of their life with equal disease incidence in males and females. The most common sinus involved was anterior ethmoid sinus, while sphenoid sinus was the least commonly involved. The most common pattern of inflammation was sinonasal polyposis followed by osteomeatal unit pattern. On correlating CT diagnosis with the final diagnosis, chronic sinusitis had 86% sensitivity and 96.5% specificity. Polyps had sensitivity of 96.15% and specificity of 95.83%. Again for fungal sinusitis, CT had a lower sensitivity of 71.4% and specificity of 93.02%. For diagnosing benign and malignant lesions, CT had 100% sensitivity and specificity, which could be due to the small number of masses evaluated. This study proved that CT is the modality of choice for evaluating and planning the management of symptomatic patients of paranasal sinus pathologies. How to cite this article Rao K.

AbstractObjectives:To analyse the radiological features of the bony nasolacrimal duct before and after functional endoscopic sinus surgery, and document the incidence of surgically induced dehiscence.Methods:A retrospective case series analysis was conducted of 63 consecutive patients who underwent uncinectomy as a part of 118 functional endoscopic sinus surgical procedures. All patients underwent pre- and post-operative computed tomography scans. Axial computed tomography images at the level of maxillary sinus were evaluated for the presence of bony nasolacrimal duct dehiscence, osteitis and completeness of uncinectomy.Results:The rate of nasolacrimal duct dehiscence prior to surgery was 6.8 per cent (8 out of 118 cases). Nasolacrimal duct dehiscence as a consequence of surgery was observed in 3.3 per cent of cases (4 out of 118), with a further 4.2 per cent (5 out of 118) showing post-operative reactive bony change of the nasolacrimal duct in the absence of dehiscence.Conclusion:The incidence of nasolacrimal duct injury observed was much lower than that previously reported in the literature.

Six patients between the ages of 6 and 22 years old with cystic fibrosis were found to have mucoceles of the paranasal sinuses. Four were male and two were female. They experienced nasal obstruction, purulent rhinorrhea, and anosmia, but none had fever or pain. Nasal endoscopy and coronal computerized tomography scans revealed the lateral nasal wall to be displaced medially against the septum. Functional endoscopic sinus surgery revealed large cystic spaces filled with thick yellow-green mucus. Postoperatively most patients are able to smell and breathe through their noses. The mucocele probably begins as an obstructed anterior ethmoid cell, which then enlarges and obstructs the osteomeatal complex, which further impairs drainage of the other sinuses into this area.

BACKGROUND The paranasal sinuses (PNS) have various anatomical difference. Computed tomography (CT) is an excellent means of providing anatomical information of this region, disease extent, assisting endoscopic evaluation and guiding treatment. Functional endoscopic sinus surgery (FESS) has become an increasingly popular treatment for chronic sinus diseases. CT of the paranasal sinuses has become a roadmap for FESS. The present study focuses on the assessment of the efficacy, safety and benefits of functional endoscopic sinus surgery in cases of maxillary pathologies and also study the anatomical variations in maxillary sinus in computed tomography and its usefulness in planning and management of chronic sinonasal diseases. METHODS It was a prospective study and a total of 80 patients were included in this study from July 2019 to June 2020 in the Otolaryngology Department, KIMS, Karad. Standard surgical steps were applied in each case according to the extent of disease. All patients underwent standard post-operative care. All findings were recorded and studied. RESULTS Total number of patients were 80. Of which, 31 (38.75 %) patients were operated for ethmoidal polyp, 24 (30 %) for chronic rhinosinusitis, 10 (12.5 %) for antrochoanal polyp, 9 (11.25 %) for rhinosporidiosis and 6 (7.5 %) for inverted papilloma. Postoperative complications were periorbital echymoses (13 %), synechiae (2.5 %), epiphora (2.5 %), infection (2.5 %), hemorrhage (4 %). Complete relief of symptoms were noted in 81.67 % cases. CONCLUSIONS Successful outcome and patient satisfaction post treatment can be obtained by careful evaluation and patient selection by history, examination and most importantly, proper imaging of the sinuses.
