观测17例半侧颜面痉挛的面肌反射和面肌肌电图,并复查了经面神经手术治疗的13例,发现本病患侧早反应活跃,迟反应和反射性反应均较健侧异常增强,并伴后发放,增强的反应可为安定抑制,种经吻合术后复发的5例异常反应又复现,本组患侧均无失神经肌电图征和直接反应异常。认为发病与面神经核下部分无关,似为面神经核异常兴奋所致,故不宜以神经吻合术治疗。 17 cases of facial hemifacial spasm hemifacial reflex and facial muscle EMG were observed and reviewed by facial nerve surgery in 13 cases and found that the affected side of the patient early reaction was active, delayed reaction and reflex compared with the contralateral abnormal enhancement , And accompanied by the release, enhanced response for the stability of inhibition, after anastomosis recurrence of 5 cases of abnormal reaction and recurrence, this group of patients with no abnormal signs of electromyogram and direct reaction abnormalities. That the incidence of facial nerve nuclei has nothing to do with the lower part of the nucleus seems to be due to abnormal excitability, it should not be treated by nerve anastomosis.
