Large-scale studies assessing complication rates and correlation of complications are still missing considering different fracture locations in the mandible. In the present retrospective study, complication rates of mandibular angle fractures treated by open reduction were assessed.
Three hundred twenty-two patients (259 men, 63 women) with 335 surgically treated mandibular angle fractures were included in this study.
Fractures were caused by fights (46.6%), falls (19.2%), traffic accidents (14.6%), sports (11.9%), wisdom tooth removal (7.3%), and 0.9% other causes. Successful treatment occurred in 93.69% of fractures with 1 open reduction and in 6.31% with 2 open reductions. Of surgically treated patients, 71.47% (238) were completely free of complications. A detailed complication correlation matrix is given in the text. Ninety-five fractures treated with 1 miniplate, 170 with 2 miniplates, and 70 with other osteosynthesis concepts were compared regarding osteosynthesis failure and pseudarthrosis.
Similar osteosynthesis failure rates were shown for 1 miniplate and 2 miniplates.
考虑到下颌骨不同的骨折部位，评估并发症发生率及并发症相关性的大规模研究仍然缺乏。在本回顾性研究中，评估了切开复位治疗下颌角骨折的并发症发生率。
本研究纳入了322例患者（259例男性，63例女性），共335例接受手术治疗的下颌角骨折。
骨折原因包括打架（46.6%）、跌倒（19.2%）、交通事故（14.6%）、运动（11.9%）、智齿拔除（7.3%）以及其他原因（0.9%）。93.69%的骨折经1次切开复位治疗成功，6.31%的骨折经2次切开复位治疗成功。在接受手术治疗的患者中，71.47%（238例）完全没有并发症。文中给出了详细的并发症相关性矩阵。比较了采用1块微型钢板治疗的95例骨折、采用2块微型钢板治疗的170例骨折以及采用其他骨固定方法治疗的70例骨折的骨固定失败和假关节情况。
1块微型钢板和2块微型钢板的骨固定失败率相似。
