摘要

这项前瞻性研究调查了关闭第二顶极电极以改善获得低频音高和第一峰信息的潜在益处,以帮助改善人工耳蜗患者的语言和音乐结果。21名植入人工耳蜗的成年人(30耳)完成了一项A-B-A-B研究,以比较所有电极激活(A)和第二大电极停用(B)时参与者的临床图谱。测试措施包括音高辨别,噪音中的语音理解,以及主观音乐音质和享受评级。本研究还调查了参与者人口统计学和电极放置因素对实验图得出的获益程度的影响(B)。在组水平上,两种情况在任何测量上都没有显著差异。然而,个体参与者在音高辨别(33.3%)、噪音下的语音感知(43.3%)、音乐音质(50.0%)和音乐享受(40.0%)方面表现出改善。音乐的音质和享受度评分有很强的相关性,语音感知与音乐享受度相关,但与音质无关。鼓室外的电极,更小的电极与耳蜗的距离,以及某些设备制造商(Cochlear和MED-EL)预测,停用第二大顶端电极会带来更大的好处。某些成人人工耳蜗使用者可能受益于选择性顶点电极失活,这取决于他们的人口统计学和电极放置概况。临床医生可以考虑对那些报告音乐音质差或接受CI后脱离音乐的患者停用第二大顶端电极,以单独评估潜在的益处。

Evaluating Selective Apical Electrode Deactivation for Improving Cochlear Implant Outcomes.

This prospective study investigated the potential benefits of deactivating the second most apical electrode to improve access to lower-frequency pitch and first formant information to help improve speech and music outcomes with a cochlear implant. Twenty-one adults (30 ears) with cochlear implants completed an A-B-A-B study to compare the participant's clinical map with all electrodes active (A) and their clinical map with the second most apical electrode deactivated (B). Test measures included pitch discrimination, speech understanding in noise, and subjective musical sound quality and enjoyment ratings. This study also investigated the impact of participant demographic and electrode placement factors on the degree of benefit derived from the experimental map (B). There was no significant difference between the two conditions on any measure at the group level. However, individual participants demonstrated improvements in pitch discrimination (33.3%), speech perception in noise (43.3%), musical sound quality (50.0%), and musical enjoyment (40.0%). Musical sound quality and enjoyment ratings were strongly correlated, and speech perception correlated with musical enjoyment but not sound quality. Electrodes outside scala tympani, smaller electrode-to-modiolus distances, and certain device manufacturers (Cochlear and MED-EL) predicted greater benefit from deactivating the second-most apical electrode. Certain adult cochlear implant users may benefit from selective apical electrode deactivation, depending on their demographic and electrode placement profile. Clinicians could consider deactivating the second most apical electrode with patients, who report poor musical sound quality or those who have disengaged from music since receiving their CI to assess potential benefits individually.

期刊介绍: Trends in Hearing is an open access journal completely dedicated to publishing original research and reviews focusing on human hearing, hearing loss, hearing aids, auditory implants, and aural rehabilitation. Under its former name, Trends in Amplification, the journal established itself as a forum for concise explorations of all areas of translational hearing research by leaders in the field. Trends in Hearing has now expanded its focus to include original research articles, with the goal of becoming the premier venue for research related to human hearing and hearing loss.
