A subject was selected strictly from 30 healthy young people through nasal endoscopic examination, acoustic rhinometry measurement and CT scanning. Based on the CT image data of the subject, digital model of normal nasal cavity was reconstructed through Fluent 6.1.22 software. At the same time, according to the surgical requirements of FESS (remove the uncinate process and open the ethmoid sinus, maxillary sinus, and sphenoid sinus), post-FESS digital nasal cavity model was simulated. The viscous motion of nasal airflow before and after FESS was calculated by Navier-Stokes equations to compare the differences of airflow velocity, distribution, and pressure.
