Objective:To evaluate role of Diagnostic Nasal Endoscopy and CT scan in various Sinonasaldiseases with regards to diagnosis and surgical intervention. Patient and methods:This prospective study was carried out in Department of ENT, A.N.M.M.C.H., Gaya on 200 patients with clinical evidence of sinonasal disease who had presented between March 2016 to February 2019. All patients were evaluated with DNE using 0 degree 4mm endoscope and CT scan with 3 mm coronal cuts. Result: Female patients(56%) were more as compared to male(44%) with majority between 21 - 40 yrs. Most common finding on Diagnostic Nasal Endoscopy(DNE) was mucopurulent discharge in middle meatuswhile on CT Scan was maxillary sinusitis(60%). Sinonasal polyp detection was better with DNE.CT has better detection rate of anatomical variation of osteomeatal complex. Conclusion : DNE has become initial tool for diagnosis as it is cost effective and office based procedure. In patients where surgical intervention is required, CT scan has advantage as it provides detailed understanding of anatomical variations. So bothDNE and CT scan should be used in collaborative fashion. Source Of Support:Patients of A.N.M.C.H., Gaya. Conflict Of Interest:None.

<p class="abstract"><strong>Background:</strong> The anatomy of paranasal sinuses is very complicated. Evaluation of the location, extent of sino nasal diseases and anatomical variations by preoperative radiologic evaluation of the paranasal sinuses is essential in planning surgical intervention. Meticulous radiographic delineation of the small structures in this region, coupled with endoscopic evaluation, provides detailed preoperative information regarding morphology and pathology.</p><p class="abstract"><strong>Methods:</strong> Patients with sinonasal symptoms indicating requirement of CT scan evaluation and aged more than 10 years were included in the study. Each CT scan was interpreted by an otolaryngologist and a radiologist and interpretation was by consensus. The data collected was evaluated and results are reported as rates and proportions.  </p><p class="abstract"><strong>Results:</strong> Sinusitis (single or multiple sinus involvement), nasal polyposis, frontal mucocele and ethmoidal carcinoma with destruction of medial wall of maxilla were the pathologies observed in these CT scans with sinusitis [22 (43.1%)] being the most common pathology observed. Deviated nasal septum [21 (41.2%)] was the most common anatomical variation observed. All patients who had concha bullosa [5 (9.8%)] were observed to have sinusitis involving multiple bilateral PNS. Based on Keros’ classification, olfactory fossa depth type I was most commonly observed followed by type II and type III.</p><p><strong>Conclusions:</strong> CT scan is important in patients undergoing endoscopic sinus surgery for sinonasal diseases where it acts as a road map in identifying the presence, extent of disease and any anatomical variations. This pre-operative CT scan evaluation improves planning and helps in significantly reducing morbidity and possible complications during surgery. </p>

The aim of this study was to measure the thickness of the mandible from the external cortical plate to the teeth roots on premolar and molar regions using CT scan to determine the safety margin for the application of monocortical screws for internal rigid fixation. Thirty-one patients underwent CT-scan imaging for surgical planning. The images were used to measure bilaterally the distance from the external cortex of the mandible to the roots of teeth on premolar and molar region by means of Dental Slice software (Bioparts Prototipagem Biomedica, Brasília, DF, Brazil). Mean, median, standard deviation, one-way ANOVA and post hoc Tukey's test were used for statistical analysis. No statistical differences for thickness were found between right and left side ( p = 0.1652). The mean thickness for the left side was 4.17 ± 1.68 mm and for right side 3.93 ± 1.49 mm. Increase in mandibular thickness from anterior to posterior regions in both sides was observed and statistical difference was found among the different groups according to the measured region ( p < 0.05). The present results can predict the safety zone for the use of monocortical screws in the mandible, but the use of CT scan is imperative and individual analysis is desired owing to anatomical variations. Further studies with larger samples are necessary to confirm these data and should include other anatomic structures, different regions of mandible/maxilla, as well as other ethnic groups.

This study aims to determine the correlation between the anatomical variations of nasal cavity and paranasal sinuses and the quality of life based on SNOT-22 score in the patients who underwent paranasal sinuses CT scan. The samples are 36 patients with age ≥ 18 years. The method is Chi Square test / Fisher's test and Spearman’s rho test. The results showed that anatomical variations of the nasal cavity and paranasal sinuses from most of the patients who underwent paranasal sinuses CT scan had septal deviation n = 29, p = 0.007 (p <0.05) and concha bullosa n = 15, p = 0.029 (p <0.05). There was a significant correlation between total anatomical variation and quality of life based on SNOT-22 score in the patients who underwent paranasal sinuses CT scan p = 0.025 (p <0.05). There was no correlation between the anatomical variations of frontal cells, agger nasi cells, ethmoid bulla, uncinate process and haller cells and the quality of life based on SNOT-22 score in the patients who underwent paranasal sinuses CT scan.

Pathological Conditions

The anatomical variations and pathological conditions of the sinonasal area can be easily identified using computed tomography (CT) scan. The study was done to observe the prevalence of concha bullosa (CB) and nasal septal deviation (DNS) in sinusitis patients. 135 CT scan of nose and paranasal (PNS) sinuses were taken and reviewed retrospectively for the presence of concha bullosa, nasal septal deviation and sinusitis in the department of Otolaryngology, Head and Neck Surgery, Border Guard Hospital, Dhaka from March 2019 to January 2020. Out of 135 patients, CT scan of nose and PNS revealed 74.81% patients exhibited some sinus disease, 68.14% nasal septal deviation and 42.22% had concha bullosa. In this study, we have done a retrospective analysis of the CT scan of PNS in order to assess the prevalence CB, DNS and sinusitis. Bangladesh J Otorhinolaryngol; April 2020; 26(1): 18-23
