| Research Abstract |
To compare a normal occlusion with jaw deformity patient and before and after operation for a jaw deformity, I researched what kind of change at the nasal cavity, pharynx and airway. As a result. Normal occlusion(control) feel nasal obstruction. In spite of high nasal resistance, there was no awareness in the control. It was suggested that nasal surface and epipharynx surface is wide and the distance from pharynx and posterior nasal spine (PW1-PNS)is long, the nasal resistance is low in normal occlusion. and that As for the nasal resistance mandibular prognathism was smaller than normal occlusion. There was not the difference of the nasal resistance by Sagital Split Ramus Osteotomy and Intraoral Vertical Ramus Osteotomy. But two jaw surgery was significantly decreased the nasal resistance.
