Background Recognising anatomical variations linked to diseased findings is highly beneficial for diagnosis and treatment. The major goal of our study was to assess different anatomical variants (superior, middle, inferior turbinate concha bullosa, uncinate bulla, and NSB) that are related to nasal septal deviation and are crucial factors to take into account when developing a diagnosis or treatment strategy. Methods The present hospital based prospective study was conducted at Department of radiology of a tertiary care hospital among 401 patients undergoing CT Brain / PNS during the study period of July 2022- September 2022. The study was done with the help of 3D reconstructed model of patients who have undergone CT for various reasons and who meet the inclusion criteria. Results were analyzed using SPSS verision27.0. Results Maximum cases are in 21-40 years that is 36.6%. In sex maximum cases are in male which is 72.9% and cases are female that is 27.1%. In side 25.1% cases are right side and 24.9% cases are of left side. Superior turbinate majority cases are bilateral which is 16.9% and 11.4% cases are Unilateral. In middle turbinate 8.5% cases are bilateral and 7.2% cases are unilateral and in inferior turbinate 4% cases are bilateral and 2.5% cases are unilateral. there is a statistically significant difference between age group and middle turbinate (p<0.05). Other variable does not show any statistically significant difference between demographic profiles (p>0.05). Conclusion In diagnosing or treating nasal septal deviation, anatomical alterations like concha bullosa are crucial. The radiologist must focus on anatomical differences during preoperative examination, and surgeons must be aware of them.
