Is the cochlear implant a successful long-term solution for single-sided deaf and asymmetric hearing-impaired patients?

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.

Automated summary

The research indicates that patients with asymmetric hearing loss or single-sided deafness benefit long-term from using cochlear implants, including improved audiological outcomes, subjective hearing perception, and reduced tinnitus burden. Most patients use their cochlear implants daily, with significant improvements in speech recognition and sound localization. Overall, cochlear implants are a successful long-term treatment option for individuals with AHL and SSD.
