Cochlear implantation in the elderly

Hearing disorders become an increasingly important issue that influences quality of life and many other economic factors. Due to the prolongation of human life and the more active lifestyles of people in retirement age, there is an increasing requirement for the available treatment options of hearing loss in the aging population. The aim of this study was to compare the hearing preservation outcomes of adult patients implanted with the Cochlear™ Nucleus® CI422 when divided into two groups by age, younger and older than 65 years of age. The study cohort consisted of 62 patients implanted from January 2011 through December 2013 at our clinic. All patients were assessed and classified according to the hearing preservation classification. Comparing the results between subgroups, we observed that the degree of hearing preservation was greater in younger adults than in older adults. Results of this review may suggest that deeper insertion is to be recommended for an older population of cochlear implant recipients.
