Cochlear implantation in the elderly: outcomes, long-term evolution, and predictive factors.

Area of Science:

• Otolaryngology
• Audiology
• Geriatric Medicine

Background:

• Cochlear implantation is a well-established treatment for severe to profound sensorineural hearing loss.
• The efficacy and safety of cochlear implantation in the elderly population require further investigation.

Purpose of the Study:

• To evaluate cochlear implantation outcomes in elderly patients (over 60 years) compared to younger adults.
• To identify predictive factors for verbal comprehension in older cochlear implant recipients.

Main Methods:

• Retrospective cohort study of 94 patients over 40 years, divided into 40-60 and >60 year groups.
• Audiometric evaluations (pure-tone, disyllabic word, phonetically balanced sentences) performed pre- and post-implantation (1, 5, 10 years).
• Analysis of peri- and postoperative complications and predictive factors in the elderly group.

Main Results:

• No significant differences in short- and long-term outcomes or complication rates between young and elderly adult groups.
• Significant predictors for elderly outcomes included side of implantation, hearing aid use, and duration of hearing loss.

Conclusions:

• Cochlear implantation is safe and effective in the elderly, offering benefits comparable to younger adults.
• While age itself has minimal impact, factors like implantation side, hearing aid use, and hearing loss duration significantly influence outcomes in older recipients.
