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）被证明是有效的，以检测一个网站的上气道阻塞。当我们计划OSAS治疗时，我们证明了FMS和CBCT联合诊断上气道阻塞的有效性。评价上颌快速扩弓对鼻腔通气、舌位、咽部气道容积的影响。RME扩大咽气道，改善或不改善鼻腔通气状态。对儿童OSAS有效。我们认为，上述结果有助于未来治疗预测模型的构建。

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.
