植入电子耳蜗,认为是和残存的树状突纤维或神经节细胞有关。确定电子耳蜗能否植入,取决于对患者植入前的外部电刺激试验的结果。在多数植入电子耳蜗的中心,术前的电刺激试验是用针电极刺入鼓岬或用尖端呈球形的电极放在圆窗龛处。作者采用一种无伤害性鼓膜外电极来对电子耳蜗植入候选者进行听神
Cochlear implants are believed to be associated with residual dendritic fibers or ganglion cells. Determine whether the cochlear implants can be implanted, depending on the results of the external electrical stimulation test before implantation of the patient. In most centers implanted with cochlear implants, the preoperative electrical stimulation test is to use a needle electrode to pierce promontory promontory or to place a sharp spherical electrode over a round window niche. The authors used a noninvasive tympanic electrode to listen to cochlear implant candidates
