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 investigate the clinical effect and application value of single screw fixation in the treatment of sagittal fractures of the mandible. Methods: Twenty-seven cases of sagittal sagittal fracture were retrospectively studied. According to the treatment, they were divided into two groups: single screw fixation group and conservative treatment group. The postoperative complications, occlusal relationship and maximal opening , Temporomandibular joint dysfunction index (DI) and muscle tenderness index (PI) were analyzed statistically. Results: There was no postoperative complications such as joint pain, limited mouth opening and ankylosis in the single screw fixation group. The indexes of DI and PI were superior to those of the conservative treatment group. The differences between the two groups were statistically significant. Conclusion: The single screw fixation is an effective means of treatment of sagittal sagittal fracture. The curative effect is exact.
