Classification of Naso Septal Deviation Angle and its Clinical Implications: A CT Scan Imaging Study of Palakkad Population, India

Abstract

Computerized tomographic imaging of the nasal and paranasal regions has become an indispensable tool for the endoscopic sinonasal surgery. The case control study was carried out on 120 patients for pilot study and 800 patients for the main study. The cases were selected with a clinical diagnosis of chronic rhino sinusitis. They were referred for a sinus CT scan by otolaryngologists and controls from the normal population. The patients were separated into males and females and anatomical variations were assessed. Increased prevalence of left sided nasal septal deviation and type II nasal septal deviation was seen in males belonging to cases group in our study. Knowledge about the nasal septum anatomical variations provides understanding about the upper limit of surgical dissection and aids in road mapping the confident direction for the functional endoscopic surgeons.
