### Description Module

**Brief Summary:** A retrospective study was conducted on 343 patients. CT PNS and head of the patients were evaluated for variants of nasal septum and nasal cavity.

**Detailed Description:** A retrospective study was conducted on 343 patients aged 13 years and above. Two investigators, each with 3 to 4 years of experience in the field of radiology, evaluated computed tomography scans of the paranasal sinuses and the head of these patients. The nasal septum was evaluated for degree and types of variants. Various variants of nasal cavities and nasal septum were also evaluated.
