目的：探讨单螺钉内固定治疗下颌骨髁突矢状骨折的临床效果和应用价值。方法：对27例髁突矢状骨折病例进行回顾研究，根据治疗方式分为单螺钉内固定组和保守治疗组，比较术后3个月两组患者术后并发症、咬合关系、最大开口度、颞下颌关节功能障碍指数（DI）和肌肉压痛指数（PI）等情况，进行统计学分析。结果：单螺钉内固定组术后未出现关节区疼痛、张口受限和关节强直等严重并发症，DI和PI各指标均优于保守治疗组，两组的差异具有显著统计学意义。结论：单螺钉内固定手术方法是一种行之有效的髁突矢状骨折治疗手段，疗效确切。

Objective:To compare the effects of single screw-fixation treatment and conservative treatment in sagittal fracture of the madibular condyle(SFMC). Method:Patients with SFMC were single-screw fixation(SSF) group and the con-servative treatment (CON) group. Index,such as occlusion, maximum opening,and function of temporomandibular joint, were recorded and analyzed. Result:All patients in the SSF group had favorable results,including good occlusion,satisfying function and without serious complications or ankylosis,etc. Conclusion:Single screw-fixation surgery is an effective treat-ment used in sagittal fracture of the mandibular condyle.
