The Finite Element Simulation of the Upper Airway of Patients with Moderate and Severe Obstructive Sleep Apnea Hypopnea Syndrome

Figure 3

Simulated modes 1–6 are shown here in images (a)–(f). In modes 1, 2, 4, and 5, the tongue vibration can be seen with displacements in different directions. In modes 3 and 6, soft palate vibrations are observed. In mode 6, there are significantly more vibration seen at the uvula.
