Four electrodes were placed in the cochlea and eighth nerve of a 57-year-old man, deafened earlier by neomycin. One electrode received over 4,000 known hours of electrical stimulation and the others fewer, but still substantial hours during extensive psychometric and speech-related testing. While tissue examination showed nerve damage in the basal turn secondary to the implant surgery, there were 18,450 surviving neurons (25,000 are normal for age). There was little or no local tissue reaction and no erosion of the electrode tips caused by electrical stimulation.
在一名57岁因新霉素致聋的男性的耳蜗和第八神经中植入了四个电极。在广泛的心理测量和与言语相关的测试期间，一个电极接受了超过4000小时的已知电刺激，其他电极接受的电刺激时间较少，但仍相当可观。虽然组织检查显示植入手术后基底转出现神经损伤，但仍有18450个存活神经元（该年龄正常为25000个）。几乎没有局部组织反应，电刺激也未导致电极尖端腐蚀。
