Before receiving a cochlear implant, an extensive evaluation is performed that includes a hearing aid evaluation, an audiological evaluation, an otological evaluation, CT scan, a speech-language evaluation, and possibly a psychological evaluation. These tests are performed to ensure that candidacy requirements have been met and that certain benefits may be provided by the implant. Counseling will also be provided by the cochlear implant team regarding the benefits and risks of cochlear implantation.

This will include the medical and surgical risks, the possible benefits to be expected, and the follow-up necessary to ensure an appropriate fitting of the speech processor and rehabilitation.
