Hemifacial spasm (HFS) caused by a venous offender is rare, and its clinical course and optimal surgical strategy are unclear. A case of 57-year-old male who had an HFS caused by a venous offender is described in this report. Frontalis, orbicularis oculi, orbicularis oris, and mentalis muscles were involved while his platysma muscle showed no spasm. He was treated successfully with microvascular decompression using Teflon felt and 12 months outcome was excellent without any complications. Lateral spread response was not observed in the facial electromyography during the whole operation. Adequate visualization of the facial nerve root exit zone and meticulous exploration for offenders are necessary to avoid surgical failure and reoperation.
由静脉压迫导致的半面痉挛（HFS）较为罕见，其临床病程及最佳手术策略尚不清楚。本报告描述了一例57岁男性因静脉压迫引发HFS的病例。该患者的额肌、眼轮匝肌、口轮匝肌及颏肌均受累，而颈阔肌未出现痉挛。采用特氟龙毡进行微血管减压治疗后，患者获得成功治愈，12个月的随访结果显示效果极佳，无任何并发症。整个手术过程中，面部肌电图未观察到侧方扩散反应。充分显露面神经根部出口区并仔细探查压迫因素对于避免手术失败及再次手术十分必要。
