A review of a test battery presented in both quiet and noise may clarify what the progression of speech perception abilities is in older adult cochlear implant users and whether the performance declines with advancing age.
To examine whether older adults (≥65 years) with cochlear implants maintain stable speech perception performance after at least 10 years of listening experience with an external speech processor.
Retrospective analysis performed in an academic tertiary care center.
Fourteen older adult cochlear implant recipients with at least 10 years of listening experience.
Speech perception outcomes as measured with Consonant-Nucleus-Consonant words in quiet and Hearing in Noise Test sentences in quiet and steady-state noise were analyzed retrospectively at the 6-month and 1-, 5-, and 10-year postoperative follow-up intervals.
Consonant-Nucleus-Consonant word scores remained stable between 6 months and 1 year of listening experience, improved significantly (P < .001) between 1 year and 5 years, and remained stable between 5 years and 10 years. Hearing in Noise Test sentence scores in quiet and noise showed a similar pattern, with stability in performance between the 6-month to 1-year and 5-year to 10-year follow-up intervals, and significantly improved performance (P = .04) between the 1-year and 5-year follow-up intervals.
On average, patients who undergo cochlear implantation at age 65 years or older do not experience a decline in speech perception performance with extended listening experience and may potentially continue to see improvements beyond the 1-year follow-up interval.
对在安静和噪声下呈现的测试组合进行评估，可能会阐明老年人工耳蜗使用者言语感知能力的进展情况，以及随着年龄的增长，其表现是否会下降。
检查至少有 10 年外部言语处理器使用经验的老年（≥65 岁）人工耳蜗植入者是否在言语感知能力方面保持稳定的表现。
在学术三级护理中心进行的回顾性分析。
14 名至少有 10 年听力经验的老年人工耳蜗植入者。
使用 Consonant-Nucleus-Consonant 单词在安静环境下和 Hearing in Noise Test 句子在安静和稳态噪声下进行的言语感知结果，在术后 6 个月和 1、5 和 10 年的随访间隔进行回顾性分析。
Consonant-Nucleus-Consonant 单词得分在 6 个月至 1 年的听力经验期间保持稳定，在 1 年至 5 年之间显著提高（P <.001），在 5 年至 10 年之间保持稳定。在安静和噪声环境下的 Hearing in Noise Test 句子得分也表现出类似的模式，在 6 个月至 1 年和 5 年至 10 年的随访间隔期间表现稳定，在 1 年至 5 年的随访间隔期间，表现显著提高（P =.04）。
平均而言，65 岁或以上接受人工耳蜗植入的患者在延长的听力经验中不会出现言语感知能力下降的情况，并且可能在 1 年的随访间隔之后继续看到改善。
