| Research Abstract |
The purpose of this research is to evaluation the nasal airflow and determine standardization of endoscopic nasal surgery.
A realistic three dimensional (3D) model of the nose with a septal perforation was reconstructed using a computed tomography (CT) scan from a noramala voluntier and patient with nasal septal defect. The numerical simulation was carried out using ANSYS CFX V13.0. The effects of surgery to correct nasal septal perforation were evaluated using a three-dimensional airflow evaluation. Following the surgery, cross flows disappeared, and PG and the SSR rate were decreased. A high PG and SSR were suspected as causes of nasal perforation symptoms.
We are planning to study other nasal/paranasal disease for standardization of endoscopic nasal surgery.
