Cochlear implantation on prelingually deafened adults

It was demonstrated that even prelingually deafened adult patients could achieve considerable improvement through CI when they were trained well by auditory-verbal/oral communications since childhood. The indications of CI for prelingually deafened adults must be determined carefully, but all of them do not have to be rejected only because they are prelingually deafened. In other words, CI could be recommended for prelingually deafened adult patients if they received habilitation well with consistent auditory-verbal/oral training using well-fitted HAs.
