Computational Fluid Dynamics (CFD) Modeling as an Objective Analytical Tool for Nasal/Upper Airway Breathing

AbstractPurpose of ReviewEmpty nose syndrome (ENS) is a rare yet debilitating disease that has been associated with aggressive removal of the inferior turbinate region in which patients report paradoxical symptoms of nasal obstruction and suffocation. The purpose of this review is to identify the mechanisms driving symptoms of ENS in patients to better alleviate them.Recent FindingsRecent studies have shown that patients with ENS have a characteristic “jet stream” of air that flows through the middle meatus when compared to healthy controls who have a dispersed pattern of airflow through all three meatae.SummaryHere, we found that the combination of altered nasal aerodynamics may contribute to a decrease in mucosal sensory function. This suggests that while ENS patients are inspiring comparable volumes of air compared to others, it is not being detected and communicated to the brain becoming interpreted as the symptoms of obstruction. Future research targeting how to improve sensory function by restoring airflow patterns should be considered to improve the efficacy of treatment for patients with ENS.
