Identifying Cochlear Implant Channels With Poor Electrode-Neuron Interfaces: Electrically Evoked Auditory Brain Stem Responses Measured With the Partial Tripolar Configuration

Conclusions: These results suggest that behavioral thresholds or EABRs measured with a restricted stimulus can be used to identify potentially impaired cochlear implant channels. Channels having high thresholds and steep growth functions would likely not activate the appropriate spatially restricted region of the cochlea, leading to suboptimal perception. As a clinical tool, quick identification of impaired channels could lead to patient-specific mapping strategies and result in improved speech and music perception.
