摘　　要：目的对面肌痉挛异常肌反应(AMR)波形进行分类,分析其波形形态特点及多样性。方法回顾性分析56例行微血管减压术的面肌痉挛院病人的临床资料。术前进行AMR检查,通过刺激面神经分支引起该分支支配的肌肉收缩(即AMR),记录诱发电位波形,分析不同波形形态,与健侧对照,判断面神经受压情况。结果 AMR存在于微血管压迫的面肌痉挛病人,本组AMR波形归类如下:经典型波形34例,时限延迟型波形6例,散射型波形8例,断续性散射型波形4例,潜伏期随刺激强度递增型波形2例,差异性传导型波形2例。结论术前AMR检查可见多种形态波形,有助于诊断微血管压迫后所致面肌痉挛,可作为手术判定指标之一。Objective To study the classification of the abnormal muscle response（AMR） waveform in hemifacial spasm, and analyze the morphological characters and variety of AMR. Methods Clinical data of 56 patients with hemifacial spasm undergoing microvacular decompression were analyzed retrospectively. AMR examination was performed preoperatively. Muscle contraction named AMR was induced by stimulating the facial nerve branches, then, evoked potential waveforms were recorded. Different waveform morphologies were analyzed and the compression situation of the facial nerve was judged by comparing with uninjured side. Results AMR waveforms were showed in hemifacial spasm patients with microvascular compression. The classification of AMR waveform was as follows： typical waveform in 34 patients, time-limit delay type waveform in 6, scattering type waveform in 8, discontinuity scattering type waveform in 4, incremental incubation period following the stimulation intensity type waveform in 2 and diversity transmission type waveform in 2. Conclusions Preoperative AMR including many kinds of waveforms is helpful for the diagnosis of hemifacial spasm after microvascular compression, and can be used as one of indexes for judging surgery.
