Int J Oral Maxillofac Surg:下颌骨骨折的固定效果——直微型钢板vs.梯形钢板

下颌骨髁下骨折占所有下颌骨骨折的25-35%。过去,大多数髁下骨折是非手术治疗的。髁下骨折的传统固定方法使用两个微型钢板;然而,一些台架研究报告说梯形板更好。近日,一项随机临床试验旨在比较两个不平行的直微型钢板或一个梯形钢板固定髁下骨折的效果,研究结果已发表于Int J Oral Maxillofac Surg。

研究连续招募了 52 名髁下骨折患者。所有患者均通过下颌后入路接受手术。比较两组骨折复位后钢板固定时间及术后疗效及并发症。

 

结果显示,梯形板组在适应容易度和固定时间方面更佳(P = 0.0001)。仅在四名 (16%) 患者的两个微型钢板组中观察到钢板断裂。两组在咬合、张口、突出和侧移方面的结果相似。

总之,两个系统:两个微型板和梯形板,可提供功能稳定的固定。梯形板组结果在植入时间和适应容易度方面明显优于两个微型板,但在其他参数方面则不然。
