Overview

The physiological nasal airflow with low resistance and low level of turbulences is necessary for normal nasal breathing. Pathological conditions (e.g. septal deviation/perforation) cause elevation of nasal resistance that patients feel like nasal obstruction. The nasal obstruction worsens quality of life. There are some possibilities how to simulate and study nasal airflow - mechanic models or computational fluid dynamics (CFD). Nowadays, CFD is dominant method for simulating nasal airflow. There is a potential to apply aerodynamic information to clinical rhinology and rhinosurgery.
