title: Cochlear implantation: a bionic system to restore hearing in severely hearing impaired patients.
abstract: CI replaces and functionally bypasses the inner haircells of the cochlea. Candidate selection is not merely based on non-aided auditory thresholds, but aided speech recognition tests in quite and in noise after a rehabilitation period may be decisive, besides a comprehensive selection process including general health, imaging, learning and cognitive skills, supportive aspect of the environment. The vast majority of severely or profoundly hearing impaired persons can benefit from CI. CI restores hearing of adults to a level allowing normal conversation, using the telephone and even understanding in a limited amount of background noise. Congenitally severely or profoundly hearing impaired children implanted before the age of 2 years, will outperform patients operated at a later age, allowing to follow mainstream education. CI is not just a technique, but the driving force behind an elaborate care-programme for the severely hearing impaired patient.
