目的：比较老年人的言语感知性能与成人人工耳蜗植入（CI）收件人在一个单一的中心在香港。设计：一项回顾性研究的14个老年人CI用户（年龄在操作，56至77岁）和14个成年人（年龄在操作，18至53岁）谁收到CI和匹配的持续时间的深度耳聋。其性能的结局指标包括基于植入后6、12和24个月时的言语感知测试评分的言语感知类别（SPC）评分为0至7。统计分析用于比较两组在测试间隔的SPC评分。同时分析两组患者在测试时间段的特定言语感知测试结果，沿着术后0 ~ 6 mo、0 ~ 12 mo和0 ~ 24 mo特定任务的改善率。多元回归分析用于评估哪些变量可以独立预测CI的结局表现。结果如下：在测试间隔，成人组和老年人组的SPC评级之间无显著差异（p 0.228至0.724）。成人组在术后0至6个月的开放式句子识别改善率（p = 0.047）方面得分显著更高，但改善速度减慢，因此在植入后12个月时与老年人组相当。在植入后24个月时，成人组在音调识别方面的得分也显著优于老年组（p = 0.031）。在测试的时间间隔内，老年组和成人组的大多数言语感知任务评分和改善率相当。多元回归分析显示，植入后12个月的日常句子识别的结果指标与深度耳聋持续时间的结果预测因子之间存在显著相关性（p = 0.025）。然而，该模型的拟合优度（r（2））为0.11，这表明，只有11%的方差在12个月术后日常句子识别解释的持续时间的深度耳聋，留下了很大比例的无法解释的variation.Conclusion：老年人Cl收件人的整体表现是可比的成人组。无论年龄大小，深度耳聋的持续时间对结果的一小部分负责。因为老年人和年轻人都可以从CI中受益，所以年龄不应该是老年人CI下降的主要因素。
Objective: To compare the speech perception performance of older adults with that of adult cochlear implant (CI) recipients in a single center in Hong Kong.Design: A retrospective study of 14 older adult CI users (age at operation, 56 to 77 yr old) and 14 adults (age at operation, 18 to 53 yr old) who received CIs and were matched for duration of profound deafness. The outcome indicator of their performance includes ratings of 0 to 7 on the speech perception category (SPC), which is based on their speech perception test scores at 6, 12, and 24 mo after implantation. Statistical analyses were used to compare SPC ratings between the two groups at the tested intervals. Results of specific speech perception tests between the two groups were also analyzed at the tested intervals, along with the rate of improvement of the specific tasks from 0 to 6 mo, 0 to 12 mo, and 0 to 24 mo postoperatively. Multiple regression analysis was used to assess which variables would independently predict the outcome performance of CIs. Results: There were no significant differences (p 0.228 to 0.724) between the SPC ratings of the adult group and the older adult group at the tested intervals. The adult group scored significantly better in the postoperative 0- to 6-mo improvement rate (p = 0.047) in open-set sentence recognition, but the improvement decelerated so that it was comparable with that of the older adult group by 12 mo after implantation. The adult group also scored significantly better (p = 0.031) in tone identification at 24 mo after implantation compared with the older adult group. The majority of the speech perception task scores, and rates of improvement were comparable between the older adult group and the adult group at the tested time intervals. Multiple regression analysis revealed a significant relationship (p = 0.025) between the outcome indicator of everyday sentence recognition at 12 mo after implantation and the outcome predictor of duration of profound deafness. However, the goodness of fit (r(2)) of this model was 0.11, suggesting that only 11% of the variance in 12-mo postoperative everyday sentence recognition was explained by duration of profound deafness, leaving a large proportion of unexplained variance.Conclusion: The overall performance of the older adult Cl recipients is comparable with that of the adult group. Duration of profound deafness, irrespective of age, is accountable for a small part of the outcome. Because older adults as well as younger adults can benefit from CIs, age should not be the predominant factor for declining CIs among older adults.
