Abstract
The influence of age on adaptation to cochlear implant (CI) is still being contested in the literature. The aim of this study was twofold. First, hearing outcomes in quiet conditions were compared between CI users implanted over and under the age of 70 years. Second, the effect of the duration of auditory deprivation was investigated. The study design is a retrospective review and the setting is in academic tertiary referral center. One hundred and twenty-one postlingually deafened implanted adults participated in this study. Hearing outcomes were compared between 121 postlingually deafened adults implanted under 40, between 40 and 70, and over 70 years of age. Speech audiometry measurements were taken at 1, 3, 6, 12, 24 and 60 months post-cochlear implantation (pCI), in quiet conditions only. Hearing outcomes were significantly better only at 1 year pCI in the youngest group compared to the two older groups. No significant difference was observed between the middle-aged and eldest subjects at any time. The influence of the severe-to-profound hearing loss (SPHL) duration was investigated and found to be equally distributed among the different age groups. Good hearing outcomes in elderly patients are not secondary to a difference in SPHL duration. Age should not be a limiting factor for cochlear implantation decision.

Notes
Tonal audiometry: mean between 500 and 1000 and 2000 Hz must be less than 85 dB, vocal audiometry must be less than 30 % recognition score at 70 dB, with no ABR peaks at 85 dB.
