To compare the clinical effects of mandibular angle fracture surgery through intraoral and extraoral approach.
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.
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.
Compared with extraoral approach to manage mandibular angle fracture with 2 miniplates, one miniplate through intraoral approach can provide better outcomes.
比较经口内入路和口外入路行下颌角骨折手术的临床效果。
回顾性纳入2008年1月至2014年12月期间46例下颌角骨折患者。其中22例采用口内入路作为第1组，骨折仅用一块微型钛板固定；其余患者采用口外入路作为第2组，骨折用两块钢板固定。所有患者术后均行颌间牵引3周。数据收集于MS Excel 2003，并采用SPSS13.0软件包进一步分析。
第1组伤口愈合顺利，3周后无并发症发生。相反，第2组观察到5例术后感染和3例面神经暂时麻痹。3个月后，术后全景X线片显示第1组下颌骨骨折愈合良好；而在第2组中，3例患者主诉骨折未愈合且咬合不满意。
与口外入路使用两块微型钢板治疗下颌角骨折相比，口内入路使用一块微型钢板可提供更好的治疗效果。
