The Effects of Various Maxillary Sinus Antrostomy Techniques on Modifying the Ventilation and Air-Conditioning Characteristics of the Maxillary Sinus: A Numerical Study.

ABSTRACT:

Background and objectives

Endoscopic sinus surgery is commonly performed for maxillary sinus (MS) disease, and the surgical extent of the MS medial wall or ostium varies. We examined the effect of MS surgery on nasal airflow and air-conditioning using computational fluid dynamics in five nasal cavity numerical models.

Methods

Four types of unilateral virtual MS surgery were conducted on the right MS based on computed tomography images of a 49-year-old man with normal anatomy. The five models were as follows: baseline (normal), middle meatal antrostomy (MMA), MMA with inferior meatal antrostomy (MMA+IMA), mega-antrostomy (MEGA), and endoscopic medial maxillectomy (EMM). Virtual simulator software and a stereoscopic display with haptic device were used for virtual surgery. Mes
