目的探讨桥小脑角上皮样囊肿显微手术治疗的效果。方法 2004年2月至2010年9月采用枕下乙状窦后入路在神经电生理监测仪保护下显微手术切除桥小角上皮样囊肿12例患者,9例平均随访24月,观察比较手术前后神经功能的变化情况。结果 12例患者术后神经功能平均改善85%,而神经显微镜下解剖保护率90%。结论显微外科治疗桥小脑角上皮样囊肿疗效满意。
Objective To investigate the effect of microsurgical treatment of cerebellopontine angle epithelioid cyst. Methods From February 2004 to September 2010, 12 patients with microscopically resected bridge small angle epithelial cyst under the protection of neuroelectrophysiological monitor were treated with suboccipital sigmoid sinus posterior approach. Nine patients were followed up for an average of 24 months. The patients underwent surgery Changes in neurological function before and after. Results After operation, the neurological function improved by 85% on average in 12 patients, while the anatomic protection rate was 90% under the nerve microscope. Conclusion Microsurgery treatment of cerebellopontine angle epithelioid cyst is satisfactory.
