Computational Fluid Dynamics Simulation of Airflow in the Normal Nasal Cavity and Paranasal Sinuses

Abstract

The major airflow forms are straight (lower common and inferior meatus) and parabolic (middle and upper common meatus and middle superior). Flow force is strongest at the front end of the inferior and middle turbinate and uncinate process. There is very little exchange between the paranasal sinus and the nasal cavity during stable airflow.
