Four cases of hemifacial spasm (HFS) are reported. The spasm followed a few months after injury to a peripheral branch of the seventh nerve. An EMG examination of facial muscles disclosed the typical finding of HFS: spontaneous activity, paradoxical cocontraction, and diffusion of spontaneous or provoked blinking. A nuclear involvement, secondary to the nerve lesion, is the most likely pathophysiological explanation for similar cases in HFS.
报告了4例半面痉挛（HFS）病例。痉挛在第七神经外周分支损伤后数月出现。对面部肌肉进行肌电图检查发现了HFS的典型表现：自发活动、反常共同收缩以及自发或诱发眨眼的扩散。继发于神经病变的核受累是HFS中类似病例最可能的病理生理学解释。
