Outcomes of Cochlear Implantation for Single-Sided Deafness and Asymmetric Hearing Loss: Quality of Life, Tinnitus, and the Effect of Deafness Duration

OBJECTIVES.: To evaluate multidimensional outcomes of cochlear implantation (CI) in adults with single-sided deafness (SSD) or asymmetric hearing loss (AHL), and to examine how duration of deafness influences speech perception, tinnitus severity, and hearing-related quality of life....

✦ Clinical Takeaway ✦

Deafness duration appears to influence cochlear implant outcomes in single-sided deafness and asymmetric hearing loss — audiologists should factor timing of intervention into counseling and referral decisions for CI candidacy.

✦ Why It Matters ✦

As cochlear implant indications expand beyond bilateral profound deafness, understanding outcome predictors like deafness duration helps audiologists counsel patients and optimize referral timing.

✦ Key Points ✦

01Cochlear implantation was evaluated in adults with single-sided deafness (SSD) or asymmetric hearing loss (AHL).
02Outcomes measured included quality of life and tinnitus severity following implantation.
03Duration of deafness prior to implantation was examined as a potential predictor of outcomes.
04Study published in Clinical and Experimental Otorhinolaryngology (PubMed PMID 42706939).
05Findings may inform patient selection criteria and timing of CI referral for SSD/AHL populations.
