摘　　要：目的:介绍发生于髁突颈和髁颈以下髁突骨折用小型钛板经下颌后进路行解剖复位、坚强内固定术的方法和经验。方法:发生于髁突颈和髁颈以下骨折24例30侧,经下颌后进路以小型钛板行坚强内固定术。术后3～6个月后复查并评价疗效,复查内容包括:张口度、张口型、咬合关系、X线表现、面神经损伤情况。结果:张口度较术前明显增大,张口型偏移明显改善,错牙合3例,面神经下颌缘支损伤2例。X线检查:髁突骨折复位良好,髁突无移位。结论:下颌后进路是一种治疗髁突颈和髁颈以下骨折的有效方法。PURPOSE:TO report the method and effects of anatomical reduction by retro-mandibular incision and miniplate rigid fixation for condylar and subcondylar fractures. METHODS:Twenty-four condylar neck and subcondylar fractures including 18 unilateral and 6 bilateral in 24 consecutive patients were studied.The fractures were approached by retromandibular incision and miniplate rigid fixation.Postoperative follow up was 3 to 6 months.The treatment results were evaluated including occlusion,joint functions as well as radiographic assessment of condylar changes. RESULTS:The average mouth opening deviation was 6.2mm before operation, which reduced to 1.4mm 3 months after surgical treatment,3 patients had malocclusion,2 had facial nerve damages. CONCLUSION:Miniplate rigid fixation by retromandibular incision based on anatomical reduction is an effective procedure in treating severely displaced and dislocated neck of condyle and subcondylar fractures.
