| Research Abstract |
(1) Computational fluid dynamics demonstrated that the levels of the base of the tongue and the soft palate improve airflow in the rigid OA group and in the Silensor group, respectively. It was suggested that both the rigid OA and the Silensor improve respiratory status, but that there are differences in the regions affected by each of the appliances.
(2) The snoring is divided into vibration type and stenosis type. In the vibration type, basic frequency is 150Hz or less, and it keeps a relatively correct period. On the other side the stenosis type, basic frequency is around 500Hz, and characteristically, it has an irregular cycle. We think that we can find an acoustic parameter to help a diagnosis of OSAS if we can clarify an acoustic characteristic of the snoring.
