Eighteen patients using the Nucleus multichannel cochlear prosthesis underwent annual evaluations for electrical thresholds, dynamic range, and speech recognition abilities for a period of 1 to 5 years. Results revealed no correlation between length of usage of a cochlear implant and electrical thresholds. The dynamic range was initially wider in the patients with open-set speech recognition, but narrowed in subsequent years. There was a correlation between length of deafness and postoperative performance.
18名使用Nucleus多通道人工耳蜗的患者进行了为期1至5年的年度评估，以检测其电阈值、动态范围和言语识别能力。结果显示，人工耳蜗的使用时长与电阈值之间无相关性。开放言语识别患者的动态范围最初较宽，但在随后几年中变窄。耳聋时长与术后表现之间存在相关性。
