Abstract

For about 20 years, Cochlear Implants have successfully restored hearing in postlingual deaf or helped to acquire auditory communication in prelingual deaf patients. However, only in recent years Cochlear Implant manufacturers have implemented stimulating and recording protocols for evoked compound action potentials in order to assess auditory nerve function in relation to the implanted device. Along with the principles of stimulation and recording of TECAPs, two cases are presented which highlight their diagnostic value as well as their limitations. While the pooled data obtained from patients are yet too variable to serve as a predictor for individual stimulation strategies, TECAPs are highly useful in intraindividual follow-up of patients in whom Cochlear Implant stimulation currents may vary even after years and who require re-adjustment according to objectively registered neural responses.
