【摘要】目的 探讨中耳乳突手术导致医源性面瘫的危险因素、处理方式及治疗效果。方法 对10例中耳乳突手术所致医源性面瘫病人进行手术探查和相应处理，术前、后按ｈouse－brackmann分级标准对面神经功能进行评价。结果 术中发现面神经损伤部位：鼓室段2例，鼓室段和锥段3例，鼓室段和乳突段3例，锥段和乳突段2例。术中进行面神经减压术6例，面神经-耳大神经移植术3例，面神经－舌下神经吻合术1例。手术前后按ｈouse－brackmann法对面神经功能进行分级，并随诊观察9个月～12年。面神经减压6例病人中5例面神经功能恢复至级，1例恢复到级。面神经-耳大神经移植术的3例从级恢复到级。面神经-舌下神经吻合的1例从级恢复至级。结论 面神经鼓室段是最容易损伤的部位。神经损伤时间长、面神经损伤程度重是面肌功能恢复不良的重要因素，应早期手术处理以使面神经功能早日恢复。
