To determine whether significant differences in cochlear implant (CI) performance exist between older and younger CI recipients.
Retrospective comparison of audiometric data.
University hospital center.
Sixty participants who received CIs at age 70 and older and 48 younger adults implanted between age 18 and 69.
Speech outcome scores (Consonant-Nucleus-Consonant words and phonemes and City University of New York Sentence test in quiet and noise).
Older participants show significant improvement in speech perception scores after implantation. Although on average they do not perform as well as younger adults, this difference correlates with duration of deafness rather than age. In contrast to younger adults, significant differences in CI performance are seen in older recipients depending on the side of implantation, with those implanted on the right performing better than those implanted on the left.
Postlingually deafened older adults obtained significant speech perception benefits from CIs, although differences in speech outcomes were seen between younger recipients and those implanted after age 70. In older adults considering CIs, hearing benefits appear greater if they are implanted in the right ear.
确定老年和年轻人工耳蜗植入（CI）受者之间的耳蜗植入（CI）性能是否存在显著差异。
回顾性比较听力学数据。
大学医院中心。
60 名年龄在 70 岁及以上的 CI 接受者和 48 名年龄在 18 岁至 69 岁之间植入 CI 的年轻成年人。
言语识别测试成绩（在安静和噪声环境下的 CUNY 单词和音位测试和句子测试）。
老年参与者在植入后言语感知评分有显著提高。虽然他们的表现平均不如年轻成年人，但这种差异与耳聋持续时间而非年龄相关。与年轻成年人不同，植入侧之间的人工耳蜗性能存在显著差异，右侧植入者的表现优于左侧植入者。
后天失聪的老年成年人从人工耳蜗中获得了显著的言语感知益处，尽管在年轻的接受者和 70 岁以上植入的接受者之间，言语结果存在差异。在考虑植入人工耳蜗的老年成年人中，如果植入在右耳，听力获益似乎更大。
