Abstract: Objectives: Cochlear implant (CI) candidates increasingly exhibit some degree of residual hearing, which should be preserved despite the implantation. Today, cochlear health is monitored during CI surgery by tracking the cochlear microphonic (CM) amplitude from intracochlear electrocochleography (ECochG) measurements. However, recent studies indicate that the insertion depth of the measuring electrode must be considered to accurately interpret these signals. The acoustic path from the cochlear base to the apex induces excitation delays in deeper regions, which should be reflected in the CM measurements. In this study, we analyzed the potential of cochlear microphonic latency (CML) as an objective method for continuously tracking CI electrode position during cochlear implantation. In addition, we examined whether CML can be associated with residual hearing.
