To determine the rate of long-term cochlear implant (CI) use in children.
Consecutive case series.
Tertiary referral center.
Approximately 474 patients younger than 18 years who received a first CI from 1999 to 2011.
Cochlear implantation.
MAIN OUTCOME MEASURE(S): Regular CI use, defined as using the CI for 8 hours or greater per day.
We successfully contacted and obtained follow-up data on 402 patients (85%) via email, telephone, and postal survey. The rate of regular CI use was 93.2% (95% CI, 90.0-95.4) at 5 years postimplantation and 87.7% (95% CI, 82.9-91.3) at 10 years postimplantation. The mean number of hours of use per day was 12.0 hours (SD, 4.1 h). Cox proportional hazard regression analysis demonstrated a linear association between the age at implantation and the risk of discontinuing regular CI use. Rates of CI discontinuation increased by 18.2% per year of age at implantation (95% CI, 7.2%-30.4%). Reported reasons for CI use less than 8 hours per day include poor hearing benefit (53.2%), social pressure (21.3%), and recurrent displacement of the transmitter coil (17.0%).
High rates of regular CI use are sustained after childhood implantation, and younger age at implantation is associated with a higher rate of continued device usage.
确定儿童长期使用人工耳蜗（CI）的比例。
连续病例系列研究。
三级转诊中心。
1999年至2011年间首次接受人工耳蜗植入的约474名18岁以下患者。
人工耳蜗植入。
定期使用人工耳蜗，定义为每天使用人工耳蜗8小时或更长时间。
我们通过电子邮件、电话和邮寄调查成功联系并获得了402名患者（85%）的随访数据。人工耳蜗植入后5年的定期使用率为93.2%（95%可信区间，90.0 - 95.4），植入后10年为87.7%（95%可信区间，82.9 - 91.3）。每天的平均使用小时数为12.0小时（标准差，4.1小时）。Cox比例风险回归分析表明，植入时的年龄与停止定期使用人工耳蜗的风险之间存在线性关联。植入时年龄每增加一岁，人工耳蜗停用率增加18.2%（95%可信区间，7.2% - 30.4%）。报告的每天使用人工耳蜗少于8小时的原因包括听力获益不佳（53.2%）、社会压力（21.3%）和发射线圈反复移位（17.0%）。
儿童期植入后人工耳蜗的定期使用率较高，且植入时年龄越小，设备持续使用率越高。
