Abstract:
Objective To study the airflow velocity, trace, distribution, pressure, as well as the airflow exchange between the nasal cavity and paranasal sinuses in a computer simulation of nasal cavity pre and post virtual endoscopic sinus surgery(ESS).Methods Computational fluid dynamics(CFD)technique was applied to construct an anatomically and proportionally accurate three-dimensional nasal model based on a healthy adult woman's nasal CT scans. A virtual ESS intervention Was performed numerically on the normal hasal model using Fluent 6.1.22 software. Navier-Stokes and continuity equations were used to flux in the common meatus decreased significantly. FIUX in the middle meatus and the connected area of significantly changed in the middle meatus. Wide-ranging vortices formed at the maxillary sinus, the Conclusions After ESS airflow velocity, flux and trace were altered. Airflow exchange increased in each nasal sinus, especially in the maxillary sinus.
