Older adults with cochlear implants (CIs) generally maintain stable speech perception over 10 years. Performance may even improve beyond the first year, showing CIs benefit long-term hearing health.

Area of Science:

  • Audiology
  • Gerontology
  • Biomedical Engineering

Background:

  • Cochlear implants (CIs) are crucial for restoring hearing in older adults.
  • Long-term speech perception changes in elderly CI users are not fully understood.

Purpose of the Study:

  • To evaluate speech perception stability in older adult CI users (≥65 years) with ≥10 years of device use.
  • To determine if age impacts long-term CI performance.

Main Methods:

  • Retrospective analysis of 14 older adult CI recipients (≥10 years experience).
  • Speech perception assessed using Consonant-Nucleus-Consonant (CNC) words and Hearing in Noise Test (HINT) sentences.
  • Data analyzed at 6 months, 1, 5, and 10 years post-implantation.

Main Results:

  • CNC word scores were stable from 6 months to 1 year, improved significantly by 5 years, and remained stable until 10 years.
  • HINT scores in quiet and noise showed similar stability from 6 months to 1 year and 5 to 10 years, with significant improvement between 1 and 5 years.
  • No decline in speech perception was observed with extended listening experience.

Conclusions:

  • Older adults receiving cochlear implants (CIs) typically maintain or improve speech perception over 10 years.
  • Performance gains can extend beyond the first year of CI use, suggesting long-term benefits.
  • Age does not appear to negatively affect long-term speech perception outcomes in CI users.
