Outline of Final Research Achievements

The aim of this study was to development of the new examination for obstructive sleep apnea syndrome (OSAS) diagnoses.
As a computational fluid dynamics (CFD) result, the oral appliance (OA) treatment improved a ventilation condition of the pharyngeal airway. And apnea-hypopnea index (AHI) of the OSAS patients before the OA treatment and pressure of epiglottic tip level showed a correlation. In conclusion pressure of CFD showed OSAS severity and velocity of CFD showed ventilator impairment site of OSAS. CFD was thought to have possibilities to become the new screening test of OSAS.
