Airflow Patterns in the Airway Passage of Nasal Obstruction Patients

Abstract

The purpose of this paper is to apply the finite element method (FEM) computation results to examine the flow field obstruction in nasal airway obstruction (NAO) patients, the consistency of the blocking site, and the elucidating the NAO phenomenon. In addition, the comparison between flow pattern of NAO patients and the healthy subject during a respiratory cycle was discussed in this article. The results of this research aimed to help optimize the treatment of NAO patients regarding the positioning and size of the surgical dissection.
