Abstract
Purpose: Unilateral cochlear implant (CI) recipients with limited hearing in the contralateral ear are deprived of the advantages of binaural hearing. To address speech recognition challenges arising from the head shadow effect, a contralateral routing of signal (CROS) device can be used; however, less is known of the broader impact of a CROS device on an individual's quality of life (QoL) or that of their frequent communication partners (FCPs). This preliminary study aimed to evaluate the impact of CROS on speech recognition in noise and its influence on the QoL of unilateral CI recipients and their FCPs.
Method: This preliminary study enrolled seven adult unilateral CI recipients and their FCPs. All CI recipients were fitted with CROS devices during their initial appointments. Speech recognition testing was conducted in noise with and without the CROS device in a sound booth before a take-home trial. Participants used the CROS devices for approximately 1 year, with device fitting occurring before and continuing during the COVID-19 pandemic. Participants completed two QoL questionnaires, the Auditory Performance and Satisfaction Scale for Single-Sided Deafness (APS-SSD) and the Nijmegen Cochlear Implant Questionnaire (NCIQ), twice: once prior to CROS device use and once after the take-home trial. Additionally, the FCPs of each CI recipient completed the Significant Other Scale of Hearing Disability (SOS-HEAR) Questionnaire twice, once before and once after extended CROS device use.
Results: When noise was directed toward the CI ear and speech toward the non-CI ear, speech recognition improved by 32% with the CROS device (p = .001). CI recipients reported significant median improvement in the "general" domain of the APS-SSD after the take-home trial (Wilcoxon Z = 12.0, p < .05). FCPs reported a significant median reduction in concerns related to their partner's hearing when the CI recipient used the CROS device (Wilcoxon Z = 2.0, p < .05).
Conclusions: This preliminary study demonstrates the benefit of CROS devices for unilateral CI recipients in noisy environments. Additionally, it highlights the positive impact of CROS devices on the QoL of both CI recipients and their FCPs. These findings emphasize the importance of considering CROS devices as a valuable solution for unilateral CI recipients to enhance their hearing experience, overall well-being, and that of their FCPs.
目的：对侧听力受限的单侧人工耳蜗（CI）受者被剥夺了双耳听力的优势。为了解决头部阴影效应带来的语音识别挑战，可以使用对侧信号路由（crs）设备；然而，crs设备对个人生活质量（QoL）或其频繁通信伙伴（fcp）的更广泛影响知之甚少。本初步研究旨在评估crs对噪声环境下语音识别的影响及其对单侧CI受者及其fcp生活质量的影响。方法：本初步研究纳入7名成人单侧CI受者及其fcp。所有CI受者在初次就诊时都安装了CROS装置。语音识别测试在带回家试验之前，在音响室中进行了有或没有CROS装置的噪音测试。参与者使用CROS设备大约1年，在COVID-19大流行之前和期间继续进行设备安装。参与者完成了两份生活质量问卷，单侧耳聋听觉表现和满意度量表（APS-SSD）和奈梅根人工耳蜗问卷（NCIQ），两次：一次在使用CROS装置之前，一次在带回家试验之后。此外，每位CI接受者的fcp在延长crs装置使用前和使用后分别填写了两次听力障碍显著性其他量表（SOS-HEAR）问卷。结果：当噪声指向CI耳，语音指向非CI耳时，使用CROS设备的语音识别提高了32% （p = .001）。CI受者报告在带回家试验后APS-SSD的“一般”领域有显著的中位改善（Wilcoxon Z = 12.0, p < 0.05）。当CI接受者使用CROS装置时，fcp报告了与伴侣听力相关的担忧显著降低的中位数（Wilcoxon Z = 2.0, p < 0.05）。结论：这项初步研究证明了crs装置对嘈杂环境下单侧CI受者的益处。此外，它还强调了crs设备对CI接受者及其fcp的生活质量的积极影响。这些发现强调了将crs装置作为单侧CI受者提高听力体验、整体健康和fcp的有价值解决方案的重要性。
期刊介绍：
Mission: AJA publishes peer-reviewed research and other scholarly articles pertaining to clinical audiology methods and issues, and serves as an outlet for discussion of related professional and educational issues and ideas. The journal is an international outlet for research on clinical research pertaining to screening, diagnosis, management and outcomes of hearing and balance disorders as well as the etiologies and characteristics of these disorders. The clinical orientation of the journal allows for the publication of reports on audiology as implemented nationally and internationally, including novel clinical procedures, approaches, and cases. AJA seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work.
Scope: The broad field of clinical audiology, including audiologic/aural rehabilitation; balance and balance disorders; cultural and linguistic diversity; detection, diagnosis, prevention, habilitation, rehabilitation, and monitoring of hearing loss; hearing aids, cochlear implants, and hearing-assistive technology; hearing disorders; lifespan perspectives on auditory function; speech perception; and tinnitus.
