| Outline of Final Research Achievements |
(1)In this study, we investigated the changes in airway form induced by oral appliances (OAs). Use of the rigid and semi-rigid OAs significantly increased the cross-sectional areas of the airway at the tongue base and soft palate levels, respectively, implying that these devices act at different sites. (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 a sleeping airway stenosis site, if we can clarify an acoustic characteristic of the snoring.
