下颌骨髁突骨折的内固定治疗

目的探讨内窥镜下微型钛板坚固内固定治疗下颌骨髁突骨折的方法。方法在内窥镜下对22例下颌骨髁突骨折患者进行骨折复位，经皮穿刺行微型钛板坚固内固定治疗。结果22例均恢复良好的面部外形，骨折愈合好，21例下颌运动正常，20例咬合关系良好。结论内窥镜下复位坚固内固定治疗下颌骨髁突骨折，手术创伤小，复位固定可靠有效，无并发症发生，适用于下颌骨髁突颈及颈下骨折的治疗。

Clinical study of internal rigid fixation for mandibular condylar fractures

Objective To investigate the clinical effect of internal rigid fixation with miniature titanium plate for mandibular condylar fracture under endoscope. Methods Twenty-two cases with mandibular condylar fractures were treated with transcutaneous puncturing and internal rigid fixation with miniature titanium plate under endoscope. Results All cases obtained a good recovery both of facial contour and bone healing. Mandibular movement was normal in 21 cases and biting function good in 20.Conclusions Under endoscope, the internal rigid fixation for mandibular condylar fracture is a good method with little trauma, accurate reduction and stable fixation but without complication and can be used for treatment of fractures of mandibular condylar neck or subcondylar condyle.
