Abstract

Cochlear implant fitting is particularly challenging in congenital and prelingually deafened children. It usually needs multiple careful and thorough sessions in order to better determine the starting level of electrical stimulation for the different speechcoding strategies adopted. In order to facilitate this task, intraoperative electrophysiological testing is most welcome. The advent, in most of the cochlear implant models, of specific software has allowed the measurement of neural action potential (AP) along the cochlear turns crossed by the electrode array (Thai-Van et al., 2001; Frank and Norton, 2001). This study has been designed to offer information regarding the utility of neural AP, when measured on an adult population, in comparison with previously utilized intraoperative tests.
