Producing deliberate damage to the facial nerve in the middle ear is an established method of treating idiopathic hemifacial spasm. However, no previous electrophysiological studies have investigated the effect of this operation on facial nerve function. Eleven patients undergoing transtympanic facial nerve needling were investigated with electromyography. Following operation reduction in the abnormal discharges and synkinesis typical of hemifacial spasm was seen in the majority of patients. The success of this type of operation, although temporary in some patients, together with other neurophysiological studies conflicts with the hypothesis that this disorder is due to ephaptic transmission caused by vascular compression of the facial nerve in the cerebello-pontine angle.
在中耳对面神经造成蓄意损伤是治疗特发性面肌痉挛的一种既定方法。然而,以前尚无电生理学研究探讨该手术对面神经功能的影响。对11例接受经鼓膜面神经针刺治疗的患者进行了肌电图检查。术后大多数患者出现面肌痉挛典型的异常放电和联带运动减少。这种手术的成功,尽管在一些患者中是暂时的,连同其他神经生理学研究结果与该疾病是由小脑脑桥角面神经血管压迫导致的假突触传递引起这一假说相矛盾。
