长期以来,对面肌抽搐、三叉神经痛和舌咽神经痛的治疗都是采用破坏神经的方法达到治疗目的。1984年5月至1986年9月,中日友好医院左焕琮等人经颅后凹对460例面肌抽搐、三叉神经痛和舌咽神经痛的桥小脑角进行显微探查,并对其中144例患者进行了显微血管减压术治疗。获得良好效果,该法的主要优点是能够保留神经,手术损伤小,并发症轻,安全度高。他们对217例面肌抽搐患者行显微血管减压治疗,术后出院时患者中57.5％抽搐停止,33.2％明显缓解,9.3％无效。对112例患者随访6～18个月,抽搐停止者增至70.5％,17.9％偶有抽搐,6.3％持续无效,5.3％复发。对140例三叉神经痛患者行显微血管减压治
For a long time, the opposite muscle twitching, trigeminal neuralgia and glossopharyngeal neuralgia treatment are used to break the nerve to achieve the purpose of treatment. May 1984 to September 1986, Sino-Japanese Friendship Hospital, left Huan-yu, who had transcranial concave 460 cases of facial muscle convulsions, trigeminal neuralgia and glossopharyngeal neuralgia bridge cerebellar angle micro-exploration, and in which 144 patients underwent microvascular decompression. Get good results, the main advantage of the law is to be able to retain the nerve, less surgical injury, complications, high safety. They treated 217 patients with hemifacial spasm by microvascular decompression, 57.5% of convulsions in patients after discharge were stopped, 33.2% were significantly relieved, 9.3% invalid. 112 patients were followed up for 6 to 18 months. The number of convulsions stopped increased to 70.5%, 17.9% occasional convulsions, 6.3% continued to be invalid, and 5.3% recurred. Thirty patients with trigeminal neuralgia underwent microvascular decompression
