Abstract
Upper airway collapse several areas in varying degrees, especially during sleep. It has been reported that the imaging results while awake do not necessarily reflect conditions during sleep, when tone of the upper airway dilating muscles is decreased. Then we should evaluate the upper airway morphology both static and dynamic manner, especially when we plan the sleep surgery.
We have been performed 3D-CT examination as a static evaluation.
Also, with DICOM data, we have been examined the inspiratory airflow simulation with computational fluid dynamics software (Phoenics).
In this paper, we showed that the usefulness of the inspiratory airflow simulation with computational fluid dynamics software.
