The prevalence of hearing loss and its consequences is increasing as the elderly population grows. As the guidelines for cochlear implantation (CI) expand, the number of elderly CI recipients is also increasing. We report complication rates, survival duration, and audiological outcomes for CI recipients aged 80 years and over and discuss the cost utility of CI in this age group.
A retrospective cohort study was undertaken of all CI recipients (126 cases), aged 80 years and over at the time of their surgery, implanted at our institution (Cambridge University Hospitals) during a period from January 1, 2001, to March 31, 2019. Data on survival at 1, 3, and 5 years post-implantation, post-operative complications and functional hearing outcomes including audiometric and speech discrimination outcomes (Bamford-Kowal-Bench sentence test) have been reported.
The mean age at implantation was 84 years. The mean audiometric score improved from 108 dB HL to 28 dB HL post-implantation. The mean Bamford-Kowal-Bench score improved from 14% to 66% and 73% at 2 and 12 months post-implantation, respectively. The complication rate was 15.3%. The survival probability at 1 year post-implantation was 0.95 for females and 0.93 for males, at 3 years was 0.89 for females and 0.81 for males, and at 5 years was 0.74 for females and 0.54 for males.
CI is safe and well-tolerated in this age group and elderly patients gain similar audiometric and functional benefit as found for younger age groups.
随着老年人口的增长，听力损失的患病率及其后果也在增加。随着人工耳蜗植入（CI）指南的扩展，老年CI接受者的数量也在增加。我们报告了80岁及以上CI接受者的并发症发生率、生存时间和听力结果，并讨论了该年龄组CI的成本效益。
对2001年1月1日至2019年3月31日期间在我们机构（剑桥大学医院）接受手术时年龄在80岁及以上的所有CI接受者（126例）进行了一项回顾性队列研究。报告了植入后1年、3年和5年的生存数据、术后并发症以及功能听力结果，包括听力测定和言语辨别结果（Bamford-Kowal-Bench句子测试）。
植入时的平均年龄为84岁。植入后平均听力测定分数从108 dB HL提高到28 dB HL。Bamford-Kowal-Bench平均分数在植入后2个月和12个月分别从14%提高到66%和73%。并发症发生率为15.3%。植入后1年女性的生存概率为0.95，男性为0.93；3年时女性为0.89，男性为0.81；5年时女性为0.74，男性为0.54。
CI在该年龄组中是安全且耐受性良好的，老年患者获得了与年轻年龄组相似的听力测定和功能益处。
