Cochlear implant (CI) trends are changing as more recipients are receiving bilateral implantation. Also more pre-lingually deafened adults are choosing to be implanted. Clinical assessment after cochlear implantation is usually based on speech perception tests. Such tests, however, may not be a realistic outcome measure for some of these cases, creating a need for more objective measures of CI performance. Cortical auditory evoked potentials (CAEPs) recorded in the sound field may be a fast and reliable procedure for the clinical audiologist to determine CI outcomes. This paper presents two case studies illustrating CAEP findings in an adult CI user who was pre-lingually deafened and a bilateral CI user.
