Bilateral cochlear implantation (CI) significantly improves speech perception in adults over 65. Outcomes were similar for sequential and simultaneous implantation and not affected by age or time between surgeries, showing advanced age is not a barrier to CI benefits.
Area of Science:
- Audiology
- Otolaryngology
- Geriatric Medicine
Background:
- Bilateral cochlear implantation (CI) is often not recommended for older adults due to cost and surgical risks.
- Evaluating outcomes in this demographic is crucial for informed clinical decisions.
Purpose of the Study:
- To assess the effectiveness of bilateral CI in post-lingually deafened adults aged 65 and older.
- To compare outcomes between sequential and simultaneous bilateral CI approaches in this age group.
Main Methods:
- Retrospective cohort study conducted at a tertiary referral center.
- Included 35 adults receiving sequential bilateral CI and 11 receiving simultaneous bilateral CI.
- Primary outcome measure was bilateral Mandarin Chinese (CNC) word scores at one year post-surgery.
Main Results:
- Both sequential and simultaneous bilateral CI led to significant improvements in CNC word scores compared to pre-operative levels.
- No significant correlation was found between speech perception improvements and age at implantation or time between implantations.
- No significant difference in one-year CNC scores was observed between sequential and simultaneous bilateral CI patients.
Conclusions:
- Bilateral CI provides significant speech perception benefits for individuals over 65, regardless of sequential or simultaneous implantation.
- Advanced age and longer intervals between implantations do not preclude positive outcomes.
- These findings support considering bilateral CI in older adults with post-lingual deafness.
