乙状窦后小骨窗微血管减压治疗血管源性面肌痉挛

目的 为探讨微血管减压治疗血管源性面肌痉挛的有效方法。方法 乙状窦后小骨窗开颅微血管减压治疗面肌痉挛187例。术中用罂粟碱生理盐水在微血管减压前后冲洗神经根部血管及术野，微血管减压后用神经钩梳理面神经。结果 术后抽搐立即停止138例，占73．8％，高于献报道50％的水平，无远期并发症的发生。结论 微血管减压后用小神经钩梳理面神经。有利于提高术后面肌痉挛立即停止的比率，用罂粟碱生理盐水冲洗神经根部及术野，有利于减少术后并发症的发生。

Treating Facial Spasm by Microvacular Decompression through Postsigmoid Sinus and Small Bone Window Approach

Objective To investigate the effective methods of treating facial spasm. Methods The blood vessels in facial nerve root and operation field were douched by the saline containing papaverine. The facial nerve was preened by never hook after the microvacular decompression. Results The facial spasm stopped immediately after the operation in 138 cases (73.8%, which was higher than 50% reported by the literature). The complications were not observed during following up from 6 months to 5 years. Conclusions Preening the facial never after the microvacular decompression is helpful to the healing of the facial spasm immediately after the operation, and douching the blood vessel in facial nerve root and operative field by papaverine saline is beneficial to the reducing the postoperative complications in the patients with facial spasm.
