Electrocochleography: Current and Emerging Applications

In this webinar, Professor at the University of Kansas Medical Center, John A. Ferraro, Ph.D., takes us through current and emerging applications of electrocochleography, also abbreviated as ECochG. Prof. Ferraro talks about ECochG components, recording approaches, electrode placement, transtympanic vs. extratympanic ECochG, recording parameters, clinical applications, and much, much more. Learning objectives: - Gain an understanding of the anatomical and physiological bases related to recording the stimulus-related potentials of the cochlea and hearing nerve in humans i.e., Electrocochleography (ECochG) - Learn the approach for performing ECochG non-invasively using an electrode on the lateral surface of the tympanic membrane (including instruction on electrode placement, and selection of stimulus and recording parameters) - Learn how to interpret an electrocochleogram and its morphology markers - Become familiar with the various clinical applications of ECochG, including those beyond its use in helping to diagnose Meniere’s disease/endolymphatic hydrops Timestamps: 0:00 Introduction 0:28 What is electrocochleography (ECochG)? 3:24 ECochG components 7:05 Recording approaches 11:02 TM electrode placement 16:14 Transtympanic vs extratympanic 19:08 Tiptrode 21:17 TM recording parameters 26:32 Clinical applications of ECochG 59:53 Enhancement of ABR wave I 1:04:06 Intraoperative monitoring 1:06:04 Cochlear implantation 1:06:32 ECochG in newborns and young children 1:08:28 ECochG in ANSD patients 1:13:57 ECochG in hidden hearing loss 1:17:29 ECochG in SSCD patients 1:19:06 Wrap up To learn more about ECochG testing, head to our guide at: https://www.interacoustics.com/abr-equipment/eclipse/support/basic-ecochg-testing-with-eclipse #Electrocochleography #ECochG Interacoustics is a world-leading diagnostic solutions provider in the field of hearing and balance assessment.
