Aerodynamic investigation of the correlation between nasal septal deviation and Chronic rhinosinusitis

Abstract

From the aerodynamics perspective, both sides of nasal cavity have the potential to predispose the occurrence of chronic rhinosinusitis in patients with nasal septal deviation. The increased deviation angle did not aggravate aerodynamic disturbance around the osteomeatal complex. The contributing role of nasal septal deviation in the pathogenesis of chronic rhinosinusitis should not be emphasized in excess.

Numerical simulation of two consecutive nasal respiratory cycles: toward a better understanding of nasal physiology

“…Computational fluid dynamics (CFD) provide a description of the movements of fluids, their properties, physical characteristics, interactions, and all the forces they are subjected to . Fluid dynamics assessment offers valuable insights into the characteristics of airflow in the nasal passages and provides a better understanding of the nasal physiology and physiopathology of certain pathologies . However, research to date has focused on the physical phenomena occurring in pathological sinonasal conditions, whereas many questions remain regarding the physiological mechanisms prevailing in a healthy nose .…”

Radiographic evaluation of nasal septal deviation from computed tomography correlates poorly with physical exam findings

“…4 Previous work has shown obstructive sinonasal anatomic variants, which are associated with nasal septal deviation, 6 to be risk factors for CRS. 10,11 Nasal septal deviation may be a risk factor for development of CRS 12,13 as well. It is not surprising then that many patients with a deviated nasal septum may additionally undergo sinus CT scan for evaluation of CRS in the setting of chronic sinonasal symptoms.…”

Anatomical Variations of Anterior Osteomeatal Complex in Patients With Chronic Sinusitis

“…This association was also shown in the current study (P = 0.032). Li believes that in terms of aerodynamics, in patients with nasal septum deviation, both sides of the nasal cavity are prone to chronic sinusitis (13). It seems that it is necessary to correct nasal deviation to address the predisposing factor in patients.…”
