Abstract

Computerized tomographic imaging of the nasal and paranasal regions is frequently used for sinonasal surgery. CBCT is another less explored modality which can provide accurate anatomic details. A retrograde study was done on 204 random scans to find out incidence and prevalence of sino-nasal anatomical variations and associated pathologies. A positive correlation was found between deviated nasal septum and concha bullosa. CBCT can sure act as a guide in future for sinonasal surgeries with lesser cost and radiation exposure. Keywords: CBCT, Deviated nasal septum, Choncha bullosa, Chronic sinusitis.

Highlights

The maxillary sinus is a pyramidal structure, dark or low in density
It extends from roof to the floor of nasal cavity, with the cribriform plate lying concha bullosa (BCB) and extensive concha bullosa (ECB).[5]
Various studies have so far suggested a variable prevalence of CB (35% to 53%), while that of deviated nasal septum (DNS) ranges from 19.4%- 65%

Summary

Introduction

The maxillary sinus is a pyramidal structure, dark or low in density. The reason behind this dark appearance is credited to minimal attenuation of x- rays by the air voids. In Cone Beam Computed Tomography (CBCT), coronal images are the most appropriate aide for viewing the co- relation of sinuses and nasal cavity. The maxillary sinuses and nasal structures can be best visualized at the level of maxillary molars.[1]. The nasal septum is seen in the midline of the nasal cavity. Various studies have so far suggested a variable prevalence of CB (35% to 53%), while that of DNS ranges from 19.4%- 65%.6
