耳后肌反应由于测试简单快速、无创伤、所得波形特殊、潜伏期相对稳定、易于识别,可作为估价面瘫患者面神经功能的一个客观方法。本组45例的结果证明,若与镫骨肌反应相互结合不仅可以有效地减少两者各自的误差,而且可以较准确地区别颞骨内和颞骨外面瘫。当镫骨肌反应由于中耳病变引不出时,耳后肌反应可取而代之。 Ear muscle reaction as the test is simple and rapid, noninvasive, the resulting waveform is special, the incubation period is relatively stable, easy to identify, can be used as facial nerve function in patients with facial paralysis an objective method. The results of 45 cases of this group proved that if combined with stapedius reaction can not only effectively reduce the respective errors between the two, but also more accurately distinguish the temporal bone and temporal bone outside the paralysis. When the stapedius reaction due to the middle ear lesions can not lead to the ear muscle reaction can be replaced.
