颜面痉挛是表情肌的不随意痉挛性疾患,病因可能与血管及血管瘤压迫面神经有关,过去治疗方法有面神经阻滞、面神经穿刺、电凝固、神经切断及神经吻合术等,这些治疗方法可致面神经麻痹,又因面神经有旺盛的再生能力,再生纤维达面部表情肌后可致痉挛复发。1934年 Dandy 行三叉神经痛治疗时,采用神经血管减压术,发现对面肌痉挛有效,1970年Jannetta 在显微镜下行此种手术治疗颜面痉挛,取得良好效果。本文作者用 Jannetta 法治疗面肌痉挛,报告一例女性42岁病程10年患者,经血管减压术,随访三年半,痉挛消失,无面瘫及
Facial spasms are involuntary spasmodic disorders of the facial muscles, which may be related to the oppression of the facial nerve by blood vessels and hemangiomas. In the past, facial nerve block, facial nerve puncture, electrocoagulation, nerve transection and nerve anastomosis were the treatment methods. Facial nerve paralysis, but also because of the facial nerve has a strong regenerative capacity, regenerative fiber up to the facial expression muscle can cause spasm recurrence. 1934 Dandy line trigeminal neuralgia treatment, the use of neurovascular decompression, found to be effective on the hemifacial spasm, Jannetta in 1970 under the microscope for such operations for facial spasm, and achieved good results. The author uses Jannetta method to treat hemifacial spasm and reports a case of 42-year-old female with a course of 10 years. The patients were followed up for three and a half years with no spasms and no facial paralysis
