Auditory Evoked Potentials and Cochlear Implants: Research Findings and Clinical Applications in Children

Auditory evoked potentials can be used to objectively assess hearing sensitivity,
central auditory processing, and neural encoding of speech sounds up to the level
of the auditory cortex. Evoked potentials have been of interest to clinicians and
researchers in the cochlear implant field for a long time because of their potential
for objectively predicting cochlear implant outcomes, as well as improving
candidacy determination, and implant programming. Neural response telemetry
and intra-operative electrical auditory brainstem recording have been routinely
performed by implant programs for many years. Recently, there has been great
interest in potential clinical applications of cortical auditory evoked potentials in
the implant field. Research and clinical applications are reviewed and case
studies are presented that illustrate clinical applications of cortical evoked
potentials in children before and after implantation.
