Multidetector computed tomography (MDCT)

Abstract

The aim of this study was to (1) detect the prevalence of anatomical variations of nose and paranasal sinuses in Chronic Rhinosinusitis (CRS) on ‘Nasal Endoscopy and Computed Tomography’, (2) study association of anatomical variations of nose and paranasal sinuses in Chronic Rhinosinusitis. This hospital based cross sectional study was performed during the period from January 2020 to October 2022 on patient between 20 to 60 yrs. of age referred to the department of Radiodiagnosis for evaluation of MDCT PNS from Dept. of ENT, S.C.B medical college and hospital Cuttack. Diagnostic Nasal Endoscopy and Computed Tomography of nose and Paranasal Sinuses of 80 patients of chronic rhinosinusitis were studied and results were. Maximum patients included in study population was 20-25 years with male predominance. Deviated Nasal Septum was the most common anatomical variation, which was detected in 70(87.5%) patients on Diagnostic Nasal Endoscopy and Agger nasii cells were observed in 60(75%) patients on Computed Tomography. The other anatomical variations like Concha bullosa 56(70%) were diagnosed both by Diagnostic Nasal Endoscopy. Anatomical variations like deviated nasal septum, agger nasi cells, medialised uncinated process, large concha bullosa were associated with chronic rhinosinusitis.
