Although cochlear implantation (CI) is thought to be a predominantly paediatric procedure, more and more adults are candidates for cochlear implants. This retrospective study was performed on 80 adults aged above 50 who were implanted for at least nine months. Results showed an improved speech perception and quality of life throughout all studied age groups. It is well recognised that CI surgery is a low risk surgery and can be safely offered to adults of all age groups. Hearing rehabilitation is important and allows adults to regain an active role and to avoid social isolation and depression especially in the older patient.
