[Cochlear implantation for adults].

A cochlear implant is an electrode, which is implanted in the inner ear to establish or re-establish hearing. Based on estimates on the prevalence of undertreated bilateral profound hearing loss, the number of adult people receiving a cochlear implant is low. In addition, many people with residual acoustic hearing or people with single-sided deafness could benefit from a cochlear implant. Due to the recent expansions in the indications for cochlear implantation and the unmet need for hearing improvement among the adult population, more focus on referring these patients to audiological cochlear implantation workup is recommended, as argued in this review.
