摘要: 目的探讨口内入路与口外入路治疗下颌角骨折的临床疗效。方法对2008年1月—2014年12月收治的46例下颌角骨折患者进行回顾分析,患者分为2组,第1组22例患者采用口内入路,用1块宽2.0 mm小钛板复位固定。第2组24例患者采用常规下颌下入路,用2块2.0 mm钛板复位固定。术后均行颌间弹力牵引3周。采用SPSS 13.0软件包对数据进行统计学分析。结果术后3周第1组患者无感染及口角歪斜发生;第2组患者5例出现感染,3例出现暂时性口角歪斜。3个月后复诊,第1组患者切口愈合良好,骨折断端愈合良好,咬合关系恢复良好,开口度正常;第2组患者3例出现骨折愈合不良,再次手术取出钛板,咬合关系欠佳。结论对于下颌角骨折,采用口内入路复位固定同样可以达到良好的治疗效果;与口外常规下颌下切口相比,口内切口创伤小,美观,不会损伤面神经,术后并发症少,手术成功率高。

Abstract: PURPOSE: To compare the clinical effects of mandibular angle fracture surgery through intraoral and extraoral approach. METHODS: From January 2008 to December 2014, 46 patients with mandibular angle fracture were retrospectively recruited in this study. An intraoral approach was used in 22 cases as group 1 in whom the fractures were fixed by one titanium miniplate alone, the others through an extraoral approach as group 2 in whom the fractures were fixed by two plates. Intermaxillary traction was used in all patients for 3 weeks following the operation. The data was collected in MS Excel 2003 and further analyzed by SPSS13.0 software package. RESULTS: The wound healing was in uneventful group 1, no complication occurred 3 weeks later. On the contrary, 5 cases with postoperative infection and 3 cases with temporary weakness of facial nerve were observed in the group 2. Three months later, postoperative panoramic radiographs showed mandible fractures healed well in group 1; while in group 2, three cases complained of unhealed fractures and unsatisfactory occlusion. CONCLUSIONS: Compared with extraoral approach to manage mandibular angle fracture with 2 miniplates, one miniplate through intraoral approach can provide better outcomes.
