OBJECTIVES: Evidence for a bilateral cochlear implant (BiCI) advantage in quiet is inconsistent, in part because many studies compare binaural versus acutely monaural conditions within BiCI users, which cannot model long-term unilateral (UniCI) adaptation....
The bilateral cochlear implant advantage for quiet speech recognition is age-independent in adults, supporting consideration of bilateral implantation across the adult age spectrum rather than restricting it to younger patients.
Age-independent bilateral benefit strengthens the evidence base for bilateral cochlear implantation in older adults, a population often under-referred for second implants.
- 01Adults with two cochlear implants show better quiet speech recognition than those with one, regardless of age.
- 02Longitudinal matched design strengthens causal inference compared to cross-sectional studies.
- 03Findings challenge age-based restrictions on bilateral cochlear implant candidacy.
- 04Published in Ear & Hearing.
- 05Quiet-only conditions tested; benefit in noise is not reported in this study.
Bilateral cochlear implant users have better quiet speech recognition than unilateral users across all adult age groups.
