目的/假设：评估成人 Clarion 1.0 人工耳蜗使用者的长期表现。 研究设计：这是一项回顾性纵向研究，评估 31 名植入前句子评分低于 10% 的成人人工耳蜗患者在安静状态下的单词辨别能力。方法：研究持续 135 个月，平均随访时间为 93（中位，96）个月。在研究期间，所有受试者均使用 Clarion 1.0 人工耳蜗，其语音处理器经过编程，可使用连续交错采样策略。 结果：植入后 24 个月后，除非发生不良医疗事件，否则语音感知没有显着增长或下降。 11 植入时的年龄与最近得分、最高得分、达到最高得分的时间、表现范围、24 至 130 个月平均得分以及测试的任何纵向数据点呈显着且显着的负相关（每十年-11% 单词得分，r=0.68）：3 至 6 个月、6 个月、1 年、2 年、5 年和 10 年。没有出现与年龄相关的表现下降。耳聋持续时间与上述任何变量之间没有观察到相关性。结论：在无残余听力的队列中，耳聋持续时间与表现之间缺乏相关性，这表明年龄与人工耳蜗植入者的言语表现之间存在很强的相关性。 10 年研究期间评分的稳定性以及装置故障或移出率为零，证明人工耳蜗是治疗重度耳聋的安全疗法。
Objective/Hypothesis: To evaluate the long-term performance of adult Clarion 1.0 cochlear implant users.Study Design: This was a retrospective, longitudinal study evaluating word discrimination in quiet for 31 adult cochlear implant patients with preimplantation sentence scores of less than 10%.Methods: The length of the study was 135 months with a mean follow-up length of 93 (median, 96) months. For the duration of the study, all subjects used the Clarion 1.0 cochlear implant with speech processors programmed for the use of the continuous interleaved sampling strategy.Results: There was no significant growth or decline in speech perception after 24 months postimplantation unless adverse medical events were experienced. Age at 11 implantation was significantly and substantially negatively correlated (-11% word score per decade, r=0.68) with most recent score, maximum score, time to maximum score, range of performance, 24- to 130-month mean score, and for any longitudinal data point tested: 3 to 6 months, 6 months, 1 year, 2 years, 5 years, and 10 years. There were no age-related declines in performance. There were no observed correlations between duration of deafness and any of the variables listed above.Conclusions: The lack of correlation between duration of deafness and performance in a cohort without residual hearing suggests the presence of a strong correlation between age and speech performance with a cochlear implant. That the cochlear implant is a safe therapy for the treatment of profound deafness is supported by the stability of scores through the 10-year study period as well as a zero rate of device failures or explantation.
