下牙槽神经损伤是下颌升支矢状骨劈开截骨术(sagittal split ramus osteotomy,SSRO)最常见的并发症,其影响因素众多,检查方法多样,发生率及恢复进程众说不一,采用恰当的预防和治疗措施可以减少术后下牙槽神经的损伤并促进其恢复。本文就SSRO术后下牙槽神经损伤产生的原因、发生率、检查方法、预防及治疗措施等进行系统介绍,为临床医生提供参考。

The damage to the inferior alveolar nerve （IAN） is the most common complication of the sagittal split ramus osteotomy （SSRO）. It is affected by many factors and can be tested by a variety of methods. There are different versions on the incidence of the IAN damage and its recovery process after surgery. Certain preventive measures and treatments can help to reduce the incidence of the IAN damage and accelerate the IAN recovery process.
