Abstract

Septal deviation (SD) in nasal cavity plays a crucial role in symptoms related to nasal obstruction, aesthetic appearance of the nose, and increase in nasal resistance, and may induce snoring. The aim of the present study was to evaluate the significance of SD on the air flow behaviour and compare its deviation with a healthy nasal cavity by using CFD. A 3D CAD model of subject specific nasal cavity was generated from CT images of patient with septal deviation. The variation of maximum WSS observed in the present study was higher when compared with that of normal subjects. In contrast to the healthy subject, the airflow in the septal deviation models showed asymmetry in bilateral nasal cavities. The maximum velocity inside the nasal cavity exceeded the value that was usually found at the nasal valve region. The findings from this study help understand the basic aerodynamics in a severely deviated septum.
