陈旧性颞下颌关节脱位的诊治

Treatment of chronic prolonged mandibular dislocations

回顾性分析5例陈旧性颞下颌关节脱位（CPMD）病例,以CT扫描作为诊断支持,患者在全身麻醉和肌肉松弛剂作用下接受了手法复位术,颌间结扎固定和颅颌绷带弹性牵引3周,术后患者最大张口度超过30mm,随访3-34月没有再次发生脱位。

5 patients with chronic prolonged mandibular dislocations（CPMD） were examined by CT scan. The patients were treated by manual reduction under general anaesthesia and muscle relaxants. Traction was performed with ligaturing steel wires on fixation titanium screws intermaxillaryly and wrapping up the skull-jaw bone with elastic bandages for 3 weeks. After 1 month,a maximal mouth opening of over 30 mm was noted and no episode of redislocation occurred in 3- 34 month follow-up.
