Evaluation of the Effect of Modified Herbst Appliance on OSAS.

目的 探索改良Herbst矫治器治疗OSAS的机制及适应证并进行疗效分析。方法 选择确诊为OSAS的男性患者 10名 ,戴入改良Herbst矫治器进行治疗。治疗前后拍头影测量片 ,并做PSG监测以评价疗效。结果 10名OSAS患者戴入Herbst后 ,下颌骨位置改变至前伸位 ,咽腔结构及其周围软组织的位置关系均发生相应变化。Ve -PVe由 (4.5± 1.7)mm增加到 (6 .4± 2 .2 )mm(P <0 .0 5 ) ,气道通气量得到增加。结论 改良Herbst矫治器是治疗OSAS的有效方法 ,对于下颌后缩、低角及软腭不太长的轻中度OSAS患者效果良好。

Objective To explore the effect,mechnism and indication of a modified Herbst appliance for treatment of OSAS.
