摘要
目的探讨面肌痉挛的病因、手术疗效及其并发症。方法对 76例保守治疗无效的面肌痉挛患者在全麻下进行减压手术 ,患者术前均进行CT或MRI检查 ,其中 14例术前进行磁共振断层血管成像 (MRTA)检查。结果 72例术中发现面神经根部出脑干区 (REZ)有血管压迫。MRTA检查面神经微血管压迫阳性率 78.6 % ,手术有效率为 90 .8% ,1年复发率为 4 % ,无致残 ,轻微手术并发症 13.2 % ,结论术前MRTA检查对面肌痉挛病因有诊断价值 ,显微减压手术治疗面肌痉挛是高效安全的治疗方法 ,熟练的显微外科技术及正确识别责任血管是手术成功的关键。
Objective To explore the etiology, the result of microsurgery and complication for hemifacial spasm. Methods Decompression was performed under general anesthesia in 76 hemifacial spasm patients who underwent ineffective conservative treatment. CT or MRI examination was made in all patients, of whom 14 were referred to MRTA examination. Results Blood vessel compression was found at the area of brain stem of the root of facial nerve in 72 cases. The positive rates for blood vessel compression of facial nerve detected by MRTA was 78.6%, the effective rate of operation was 90.8% and one-year recurrent rate was 4%. Disability did not occur and only 13.2% were detected for slight operation complication. Conclusion Preoperative MRTA examination is valuable to the diagnosis of the etiology of facial spasm. The keys to the successful operation are the high-effective Methods of microdecompression for treating facial spasm, the proficient microsurgical technique and the correct identification of offending blood vessel.
