Intraoperative Intracochlear Electrocochleography and Hearing Preservation Early after Cochlear Implantation: A Meta-Analysis

Abstract

Abstract – Aim: There are a range of approaches to intraoperative electrocochleography (ECochG) monitoring across different implant systems, and these show inconsistent results. Here, we synthesize by meta-analysis the evidence for real-time intracochlear ECochG recorded during cochlear implantation predicting residual hearing. Methods: Inclusion criteria included original studies in which real-time ECochG was undertaken on a commercial cochlear implant (CI) and residual hearing outcomes at least 4 weeks after implantation were reported. Thirteen studies comprising 313 individual patient data sets met inclusion criteria. Full data sets were sought from the authors. Studies were rated for qua..
