Mapping for pediatric cochlear implant recipients using the electrically evoked compound action potential (ECAP)

Objective: To establish a mapping protocol for infants and young children cochlear implant recipient who are not able to finish psychophysics test. Methods: 16 pediatric cochlear implant recipients have been recorded electrical evoked compound action potential (ECAP) of auditory nerve via the neural response telemetry (NRT) technique. Results: There are good relationship between the ECAP threshold and psychophysics T level, relation coefficient r = 0.63 (P = 0.0000). Conclusions: ECAP thresholds would be practical tool in estimating map parameters.
