Modeling nasal physiology changes due to septal perforations.

ABSTRACT:

Objective

To use computational fluid dynamics (CFD) technology to help providers understand (1) how septal perforations may alter nasal physiology and (2) how these alterations are influenced by perforation size and location.

Study design

Computer simulation study.

Setting

Facial plastic and reconstructive surgery clinic.

Subjects and methods

With the aid of medical imaging and modeling software, septal perforations of 1 and 2 cm in anterior, posterior, and superior locations were virtually created in a nasal cavity digital model. The CFD techniques were used to analyze airflow, nasal resistance, air conditioning, and wall shear stress.

Results

Bilateral nasal resistance was not significantly altered by a septal perforation. Airflow allocation changed, w
