摘　　要：目的　总结陈旧性脱位性髁突骨折的手术治疗经验。方法　经患侧绕下颌角切口 ,将2 2例脱位髁突游离再植 ,通过X线对比观察、咬合关系恢复程度、张口度及张口型改善等指标进行评价。结果　 19例咬合关系恢复正常 ,19例髁突复位良好 ,关节间隙均匀 ,骨皮质光滑、连续。平均张口度由 2 8 9mm增至 39 2mm ;均有明显改善 (P <0 0 1)。结论　髁突游离再植有利于结构和功能的恢复 ,是治疗陈旧性脱位性髁突骨折的有效方法。Objective To analysis the result of surgical treatment on old dislocated condylar process fractures Methods 22 cases of old dislocated condylar process fractures with a duration of more than 3 weeks (average 4 6 weeks)were treated by free and reimplantation of the dislocated condylar process The postoperative result was evaluated on the basis of occluding relation and joint function, as well as radiographic assessment of condylar changes Results Normal occluding relation was resumed in 19 cases after the operation And there were 19 cases showing that the process was replaced in normal position, and homogeneous joint space and smooth cortex surface of the process were showed on pantomography also The average mouth opening was 28 9 mm and the average mouth opening deviation was 6 3 mm before the operation reduced to 1 4 mm 6 months after the surgical treatment Conclusions The structure and function were recovered postoperation in 86 percent of the cases, with only slight complications in several patients So the free and reimplantation was an effective method in treating old dislocated condylar process fractures
