Clinical Utility of Residual Hearing in the Cochlear Implant Ear

"The use of ECochG monitoring will be employed. This will be conducted intraoperatively during the entire portion of the CI electrode insertion component.~For the purposes of this clinical trial, the stimulus will consist of a 500 Hz tone burst presented at \~105-110 dB SPL. This was chosen due to the time and resource limitations in the operating room. Hence, the surgical team can only utilize a very limited dataset for intraoperative decision making and previous studies have demonstrated that 500 Hz stimulation offers the most robust, reliable, and useful ECochG signal during electrode insertions."
