Abstract

We investigate the upper airway dynamics with these clinically accurate kinematics and geometries. We use smoothed particle hydrodynamics (SPH) modeling of water-like and nectar-like fluid boluses, simulated within an airway-skin mesh that encompasses our modeled 3D structures and follows the model's dynamics. We demonstrate that our model can simulate a bolus in a manner consistent with clinical data, and can robustly handle fluid with different viscosity incorporating a wide range of moving boundary conditions.

We present a three dimensional (3D) biomechanical swallowing model of the oral, pharyngeal and laryngeal (OPAL) muscles and structures. Such modeling may aid in predicting functional outcomes in swallowing disorder (i.e. dysphagia) treatment and could significantly reduce therapy time.
