目的：分析髁状突骨折行钛板内固定术后失败的原因。方法收集2003年4月～2012年4月完成的髁状突骨折行钛板内固定术患者，术后随诊复查， X光片及CT检查。根据骨折部位分为髁突囊内骨折，髁突颈部骨折，髁突基部骨折3组，对3组骨折术后愈合情况进行回顾性分析。结果210例随访病例中，术后咬合关系恢复不良30例；螺钉松动57枚，钛板断裂0例，面神经颧支损伤15例，面神经颞支损伤30例，张口受限伴有下颌偏斜35例。结论术中面神经损伤，术后感染、不适当的应力集中、钛板和螺钉的数量、是否固定于理想部位、忽视术后短期颌间牵引固定，关节周围相关软组织是否良好复位为髁突骨折坚强内固定手术失败的相关因素。

Objective:Analysis of the causes of failure in condylar fracture internal fixation.Methods: Col ect the cases from April 2003 to April 2012 .Postoperative examination x-ray and ct,Divide the cases into 3 groups: Intracapsular condylar fracture; Condylar neck fractures; Base of condylar fracture. Result: In the 210 Fol ow-up cases, Malocclusion 30;Screws loose 57;Titanium plates fracture 0; Zygomatic branch of facial nerves injury 15; Temporal branch of nerves injury15;Limitation of mouth opening and Mandibular deviation 35;Conclusion:Facial nerve injury; Infection; Undue stress concentration;Titanium plate and titanium nail whether or not in the ideal position;Ignore the intermaxil ary traction;Periarticular soft tissues reset are Factors related to operations failure.
