Identification of ventilation obstructionsite of OSAS of children by the fluid simulation and construction of the treatment predictive model

流体力学模拟（FMS）可以有效地检测上气道梗阻部位。当我们计划OSAS治疗时，我们证实了FMS和CBCT联合诊断上气道阻塞的有效性。评价上颌快速扩张（RME）对鼻腔通气、舌位、咽部气道容积的影响。RME扩大咽道气道，改善或不改善鼻腔通气状态。这对阻塞性睡眠呼吸暂停症儿童有效。我们认为上述结果有助于构建未来治疗预测模型。

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.
