Cochlear implants (CI) candidacy criteria have expanded to include children with more residual hearing. This study explored the clinical profiles and outcomes of children with CIs who had preoperative residual hearing in at least one ear.
A retrospective chart review was conducted to collect clinical characteristics and speech perception data. Pre- and post-CI auditory and speech perception data were analysed using a modified version of the Pediatric Ranked Order Speech Perception (PROSPER) score.
This study included all children with residual hearing who received CIs in one Canadian paediatric centre from 1992 to 2018.
A total of 100 of 389 (25.7%) children with CIs had residual hearing (median 77.6 dB HL, better ear). The proportion of children with residual hearing increased from 1992 to 2018. Children who had auditory behaviour and speech perception tests (n = 83) showed higher modified PROSPER scores post-CI compared to pre-CI. Phonologically Balanced Kindergarten (PBK) test scores were available for 71 children post-CI; 81.7% (58/71) of children achieved > 80% on the PBK.
One in four children who received CIs had residual hearing, and most of them had severe hearing loss at pre-CI. These children showed a high level of speech perception with CIs.
人工耳蜗（CI）的候选标准已经扩大到包括具有更多残余听力的儿童。本研究探讨了术前至少一只耳朵具有残余听力的 CI 儿童的临床特征和结果。
进行了回顾性图表审查，以收集临床特征和言语感知数据。使用小儿排名言语感知（PROSPER）评分的修改版分析术前和术后 CI 的听觉和言语感知数据。
本研究包括 1992 年至 2018 年在加拿大一家儿科中心接受 CI 的所有具有残余听力的儿童。
389 名接受 CI 的儿童中有 100 名（25.7%）具有残余听力（中位数为 77.6dB HL，较好耳）。具有残余听力的儿童比例从 1992 年增加到 2018 年。进行了听觉行为和言语感知测试的儿童（n=83）在 CI 后显示出比 CI 前更高的改良 PROSPER 评分。在 CI 后，71 名儿童获得了语音平衡幼儿园（PBK）测试成绩；81.7%（58/71）的儿童在 PBK 上获得>80%的成绩。
接受 CI 的儿童中有四分之一具有残余听力，他们中的大多数在 CI 前有严重的听力损失。这些儿童使用 CI 表现出较高的言语感知水平。
