Research Abstract

Fluid mechanical simulation (FMS) was proved effective for detecting the location of upper airway obstructions. The investigation clearly proved the effectiveness of combining FMS and CBCT to diagnose obstructions of the upper airway that might be important in planning OSAS treatment. And it was comprehensively examined that the effect of rapid maxillary expansion (RME) on the nasal airwayventilation condition, tongue posture and pharyngeal airway volume. RME enlarges the pharyngeal airway both with and without improvement in nasal obstruction. This effect is effective for OSAS of children.
