摘　　要：目的探讨全程内镜下经枕下乙状窦后锁孔人路桥小脑角表皮样囊肿切除术的方法和特点。方法回顾性分析6例桥小脑角表皮样囊肿病人的临床资料，均采用全程内镜下经枕下乙状窦后锁孔入路切除囊肿。结果6例囊肿及其包膜全部切除。术前症状完全消失。术后出现轻微面瘫1例，2周后恢复；出现面瘫、听力下降1例，3个月后恢复。全部病人无需拆线，术后3—5d出院。6例病人随访6—12个月未见复发。结论在合理使用手术器械和掌握手术技术前提下，全程内镜下经枕下乙状窦后锁孔入路是一种治疗桥小脑角表皮样囊肿的安全、有效方法，具有创伤小、观察清楚、视野死角小、住院时间短等优点。Objective To investigate the surgical techniques and characteristics of resection of epidermoid cyst in the cerebellopontine angle by fully neuroendoscopic suboccipital retrosigmoid keyhole approach. Methods Clinical data of 6 patients with epidermoid cyst in the cerebellopontine angle were analyzed retrospectively, all of whom underwent resection of epidermoid cyst by fully neuroendoscopic suboccipital retrosigmoid keyhole approach. Results The capsule and its contents were totally removed and the preoperational symptoms disappeared alter surgery in all the patients. The slight facial paralysis occurred in 1 patient who recovered 2 weeks atter surgery. The facial paralysis and hearing loss occurred in 1 patient who recovered 3 months atter surgery. No stitch had to be removed in 6 patients who were discharged 3 to 5 days aiter surgery. All the patients were followed up for 6 to 12 months and no relapse. Conclusions Based on reasonable use of operative instruments and mastery of techniques, surgical resection via fully neuroendoscopic suboccipital retrosigmoid keyhole approach is a safe and effective treatment for epidermoid cyst in the cerebellopontine angle, and has such advantages as small incision, more clear observation, smaller dead angle and shorter hospitalization.
