This series of projects aims to establish the method of electrocochleography (ECochG) during and following cochlear implantation. This has been an ongoing effort since 2005 the initial goal was to establish an algorithm that would allow to monitor cochlear health during electrode insertions. This has since been realized and current projects focus on improvements to the present system as well as to explore this method for cochlear implant mapping, performance prediction, and other topics.

This NIH funded and FDA approved clinical trial aims at establishing the potential of ECochG monitoring in cochlear implant candidates with substantial residual hearing and to determine the value of the presence and the amount of ipsilateral residual hearing on postoperative outcomes such as hearing and quality of life.

The aim of this project is to continue to enhance our understanding of the clinical parameters relevant when considering cochlear implantation in adult and children with single sided deafness.
