目的 :探讨中耳乳突手术引起面瘫的原因、预防和治疗方法。方法 :对 1976～ 1991年的 10 32例行中耳乳突手术并发面神经麻痹的 2 3例进行回顾性分析。结果 :2 3例均为不完全性周围性面瘫。作面神经减压术 13例 ,治愈 6例 ,好转 4例 ,无效 3例。保守治疗 10例 ,治愈 5例 ,好转 3例 ,无效 2例。结论 :即发型面瘫在排除麻醉药所致外 ,就意味着神经损伤 ,应立即探查神经并减压。迟发型面瘫首选保守治疗 ,预后较好 ;1个月后仍无效者 ,再手术。
Objective: To investigate the causes, prevention and treatment of facial paralysis caused by middle ear mastoid process. Methods: A retrospective analysis was performed on 2332 cases of middle-to-middle-ear mastoidectomy complicated with facial paralysis between 1976 and 1991. Results: All 23 cases were incomplete peripheral facial paralysis. For facial nerve decompression in 13 cases, 6 cases were cured, improved in 4 cases, 3 cases were ineffective. Conservative treatment in 10 cases, cured in 5 cases, improved in 3 cases, 2 cases. Conclusions: Facial paralysis in the exclusion of anesthetic drugs, it means that nerve damage, nerve should be immediately probe and decompression. Delayed facial paralysis preferred conservative treatment, the prognosis is good; one month after the still ineffective, and then surgery.
