This study compares the internal fixation of mandibular fractures using either rigid 2.7 mm AO/ASIF plates or mini-plates. In the rigid plate group, 88 fractures were fixed with 88 plates. In the mini-plate group, 116 fractures were fixed with 170 plates. All the cases were consecutive and were treated in two South Wales hospitals during a 3-year period from 1988 to 1991. The aetiology of injury, timing of surgery, site of fracture, antibiotic policy and demographic features were evenly distributed between the two groups but there was a higher incidence of females in the mini-plate group. Both plating systems were successful in restoring functional occlusion. Rigid plates avoided the use of postoperative elastics better than mini-plates but the difference was not significant. There was a significantly higher incidence (P = 0.013) of infection in the mini-plate (12.9%) compared with the rigid plate (2.3%) group but 7.9% of the rigid group developed facial nerve weakness. A significantly higher proportion of mini-plates needed to be removed (P = 0.00019). A better treatment outcome for angle and comminuted fractures was noted with rigid plates.
本研究比较了使用2.7毫米AO/ASIF坚固接骨板或微型接骨板对下颌骨骨折进行内固定的效果。在坚固接骨板组中，88块接骨板用于固定88处骨折。在微型接骨板组中，170块接骨板用于固定116处骨折。所有病例均为连续病例，于1988年至1991年的3年期间在南威尔士的两家医院接受治疗。两组在损伤病因、手术时机、骨折部位、抗生素使用策略及人口统计学特征方面分布均衡，但微型接骨板组女性发病率较高。两种接骨板系统均成功恢复了功能咬合。坚固接骨板在避免术后使用弹力牵引方面优于微型接骨板，但差异不显著。微型接骨板组感染发生率（12.9%）显著高于坚固接骨板组（2.3%）（P = 0.013），但坚固接骨板组有7.9%出现面神经麻痹。需要取出的微型接骨板比例显著更高（P = 0.00019）。对于角部骨折和粉碎性骨折，坚固接骨板的治疗效果更佳。
