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, assisting with candidacy decisions, and implant programming. In children and adults who are candidates for CIs auditory evoked potentials (electrocochleography, ECochG; electrical auditory brainstem response, EABR; cortical auditory evoked potentials, CAEPs) can be used to assess objectively assess cochlear and neural function in order to determine candidacy for implantation and as an indicator of speech perception outcomes. This is particularly useful in difficult cases such as auditory nerve insufficiency and auditory neuropathy spectrum disorder (ANSD). Neural response telemetry (NRT) and EABR have been routinely performed intra-operatively by implant programs for many years to evaluate implant and neural integrity and guide surgical decisions. Post-implantation CAEPs can be used to assist with mapping and to guide therapy by providing information on central auditory function and speech sound processing at the level of the auditory cortex. There has been increasing interest in clinical applications of cortical auditory evoked potentials in the implant field. This presentation will review research and clinical applications of auditory evoked potentials in the cochlear implant field and case studies illustrating clinical applications.
