Real Time Monitoring during Cochlear Implantation: Increasing the Accuracy of Predicting Residual Hearing Outcomes

Abstract

Objectives:Real-time electrocochleography (rt-ECochG) is a method to detect intracochlear potential changes during cochlear implantation (CI). Steep amplitude drops of the cochlear microphonic (CM) signal (so called "ECochG events") have been correlated with worse residual hearing outcomes. However, the sensitivity and specificity of monitoring CM amplitude on its own are too low to use it as a biomarker. The aim of this article was to establish if additional signal components would help to better predict postoperative hearing outcomes.Design and Setting:Single-center, prospective cohort study at a tertiary referral hospital.Participants and Interventions:Between 2017 and 2020, we included 7..
