| Research Abstract |
The fluid mechinical simulation (FMS) was shown to be effectiveto detect a site of the upper airway obstruction. When we planned OSAS treatment, we proved efficacy of the combination of FMS and CBCT to diagnose the obstruction of the upper airway. And we evaluated the effect to nasal cavity ventilation, tongue posture, the pharynx airway volume of the maxillary rapid expansion (RME). RME enlarged pharynx airway with or without the improvement of the nasal cavity aeration state. This effectis effective for OSAS of children. We consider that the above-mentioned results help the construction of the future treatment predictive model.
