Early cochlear implantation: exploring electrophysiological thresholds and their role in pre-behavioural recommendations.

Background And Aims: Studies investigating the relationship between initial electrophysiological thresholds and subsequent behavioural hearing thresholds have demonstrated uncertainty as to whether initial results can provide an accurate estimation of an infant's functional hearing. This estimation must be accurate if a cochlear implant (CI) is to be considered before behavioural audiometry.This study aims to explore the variance between initial electrophysiological thresholds and subsequent behavioural hearing thresholds in infants to determine under which conditions electrophysiological results can be used to support a CI recommendation before behavioural audiology.
