摘　　要：目的:探讨杠杆原理在颞下颌关节脱位复位中的应用。方法:本组85例,急性脱位28例,复发性脱位52例,陈旧性脱位5例。通过杠杆原理对急性前脱位和复发性脱位进行复位;对陈旧性脱位给予持续三类牵引及垂直牵引力复位。结果:急性前脱位和复发性脱位均成功复位;陈旧性脱位4例成功复位。结论:利用杠杆原理对急性前脱位及复发性脱位复位速度快,力量小,可以避免咬伤术者手指;对陈旧性脱位有较好效果,可作为首选复位方法。Objective：To study the reduction of the dislocation of temporomandibular joint by lever. Method：TMJ reduction is perfornled by lever on acute and recurrent dislocation of condyle： Vertical and class Ⅲ distraction are performed by lever on the prolonged dislocation of condyle. Result： The reduction is successful on acute and recurrent dislocation of condyle; 4 cases of prolonged dislocation of condyle are successful. Conclusion： The advantages of reduction by lever are fast and less power . Vertical and class Ⅲ distraction by lever should be the first choice for the prolonged dislocation of condyle.
