Effect Of Functional Endoscopic Sinus Surgery To The Flow Behavior In Nasal During Resting Breathing Condition

Abstract

Functional endoscopic sinus surgery (FESS) is a surgery to remove
uncinate process in order to restore sufficient sinus ventilation and drainage
in nasal. However, there were a few cases with side effects such as facial
pain, reduction in sense of smell and sinusitis reoccurrence of infection. In
this study, the effect of uncinate process removal is investigated. Images of
the model were done through computational technique and then the flow
was simulated to predict the effect of the removal. Inhalation processes with
resting breathing condition were modeled. The results show that smooth
flow was observed at nasal area which indicates successful surgical process.
However for post FESS model the result shows that the possibilities of
sinusitis reoccurrence of infection were high. Finally, velocity profile in the
olfactory area show non-favorable flow condition for effective smell senses.
