神经内窥镜辅助微血管减压治疗面肌痉挛

目的探讨在神经内窥镜辅助下对原发性面肌痉挛病人行微血管减压术的疗效和优点.方法我院1999年4月～2001年10月间采用枕下乙状窦后入路,在神经内窥镜的辅助下对16例原发性面肌痉挛病人行微血管减压术.结果 16例病人术后症状均消失;无听力障碍,面瘫和脑脊液漏等并发症;随访1年无复发.结论神经内窥镜辅助下的微血管减压术能清晰显示神经血管的解剖关系,可减少对脑干、各颅神经的牵拉和重要血管的损伤,对提高手术疗效、减少复发率和术后并发症有重要价值.

Neuroendoscopy-assisted microvascular decompression for hemifacial spasm

Objective To assess the efficacy and advantages of endoscope-assisted microvascular decompression for the treatment of primary hemifacial spasm. Methods Sixteen patients with hemifacial spasm underwent endoscope-assisted microvascular decompression via a minimally invasive suboccipital approach between April 1999 and October 2001. Results All patients experienced resolution of the preoperative symptoms after the surgery. There were no complications of hearing loss, hemifacial paralysis, cerebrospinal fluid leakage, and so on. After 1-year follow-up, no recurrence happened. Conclusion Endoscope-assisted microvascular decompression improves the observation of the anatomic neurovascular relationship with less retraction of the brainstem, nerves and less damage to the vessels. It has great value in elevating the efficacy, decreasing the potential complications and the recurrent rate.
