Computational fl uid dynamics-based numerical modelling of airfl ow in the upper airway
Abstract
In scientific literature, there is a strong correlation between the development of the craniofacial region and the upper airways (UA). Distal occlusion and other forms of malocclusion are risk factors for the onset of obstructive sleep apnea syndrome, according to contemporary theories. By estimating aerodynamic flow characteristics in the UA, such as regional flow velocity, pressure, and turbulent kinetic energy profiles, computational fluid dynamics (CFD) enables understanding of how the shape of the UA effects their function. With the use of 63 CBCT scans of adult patients with normal, distal, and mesial sagittal malocclusions, we were able to generate numerical meshes for CFD calculations using the ANSYS Fluent program. We have discovered that the maximum velocity and pressure decrease, which are typical of OSAS patients, occur in individuals with distal occlusion and extended head posture.
