Benefits of Cochlear Implants
Benefits of Cochlear
Implants
- Adults often benefit immediately and continue to improve for about 3 months after the initial tuning sessions.
- Cochlear implant users' performances may continue to improve for several years.
Success Rates of Adults with Cochlear Implants
Success Rate
82.0% of adults with postlingual hearing loss and 53.4% of adults with prelingual hearing loss improved their speech perception ability by 15 percentage points or more.
Success Rates of Cochlear Implants in Children
Success Rates of Children
- For patients implanted at 12 to 35 months of age, the cumulative rates of regular CI use were 95.3% (95% CI, 90.3-97.7) at 5 years post-implantation, 92.6% (95% CI, 85.6-96.3) at 10 years post-implantation, and 86.7% (95% CI, 68.8-94.8) at 13 years post-implantation.
Factors that can affect the benefits
- The age when hearing was lost.
- Length of time between hearing loss and the cochlear implant surgery.
