Abstract Purpose We investigated the long-term results of cochlear implant (CI) recipients with asymmetric hearing loss (AHL) or single-sided deafness (SSD). We focused on wearing behavior, audiometric hearing rehabilitation, and subjective benefits of the CI. CI is expected to improve audiological results, subjective hearing perception, and tinnitus burden. Methods Speech recognition in background noise and sound localization were assessed preoperatively and after at least six years of CI experience. Validated questionnaires determined the subjective benefit of CI use and the subjective evaluation of tinnitus. Results Over 80% of the included AHL and SSD CI recipients used their CI between 6 and 10 h daily; four subjects with SSD were non-users. Speech recognition in background noise and sound localization improved significantly compared with the unaided preoperative situation. Additionally, CI improved subjective speech intelligibility and spatial hearing impression while reducing tinnitus burden. Conclusion Subjects with AHL and SSD benefit from CI, subjectively and audiologically. Cochlear implant is a successful long-term treatment for AHL and SSD.

Introduction The extreme asymmetry of hearing impairs individuals with single-sided deafness (SSD) and asymmetric hearing loss (AHL) in their speech recognition in noise and the localization of sound sources [1–5]. SSD and AHL can also cause psychological health issues, e.g., high-stress levels, high self-reported listening effort, low self-efficiency, and low self-confidence, resulting in exhaustion, frustration, and social withdrawal [5–8]. In addition, many AHL and SSD patients experience disturbing tinnitus [2, 9–11]. Cochlear implants (CIs) improve speech recognition in noise and the localization of sound sources in patients with SSD [12–15]. CIs also reduce the cognitive load and improves the anxiety states and hearing-related quality of life of such patients [1, 2, 10, 11, 16]. In the first and, to date, only long-term study on SSD CI recipients, Távora-Vieira and colleagues compared the conditions of CI turned on and CI turned off at the time of
