Outline of Final Research Achievements	Maxillomandibular advancement is very effective treatment for obstructive sleep apnea syndrome. However, the amount of effective displacement. In this study, we examined the change of oropharyngeal airway using CFD and change of breathing during sleep following orthognathic surgeries with madibular advancement. As the result, the upper volume was significantly increased after surgery.
