For individuals who have undergone cochlear implantation, six studies investigating the diagnostic accuracy of electrocochleography (ECochG) to predict postoperative hearing loss reported sensitivity ranging from 48% to 100%, indicating a high rate of false negatives, and specificity ranging from 0% to 100%, indicating a high rate of false positives. The studies included in this review demonstrated heterogeneity in ECochG recording technique and waveform interpretation. The authors conclude that the accuracy of ECochG to predict postoperative hearing loss is limited and requires further investigation to determine if it has appropriate reliability and accuracy to be used as a surgical tool.
