eABR in Cochlear Implantation: Using the CI as an Electrical Stimulator

In this recorded webinar, Dr. Martin Walger, Ph.D., explains the physiological basics of the electrical auditory brainstem response (eABR) and indication criteria for pre-, peri- and post-operative evaluation of cochlear implant (CI) candidates.

Using case study videos, Dr. Walger then explores the methods of performing eABR recordings in children and adults, including quality assessment, before discussing the interpretation of results for both normal findings and pathological cases.

Dr. Martin Walger is Professor of Audiology and Head of the Department of Audiology and Pediatric Audiology at the ENT University Clinic as well as the Audiological Head of the Cochlear Implant Center of Cologne, Germany. Educated in the fields of biology and audiology, he earned his Ph.D. investigating effects of noise on the central auditory pathway. His scientific research concentrated on the maturation and plasticity of the auditory system under the influence of hearing loss. Dr. Martin Walger is past-president of the German Society of Audiology (DGA) and Council member of the International Evoked Response Audiometry Study Group (IERASG).
