Abstract		Background: Electrical auditory brainstem response (EABR) is an electrophysiologic measurment used for preoperative evaluation of candidates for cochlear implantation. Direct respones of the auditory nerve to eletric stimuli are recorded. Neural response telemetry (NRT) is an indirect measurment of electrically evoked action potentials of the auditory nerve through the cochlear implant. It is performed in the operating room or after surgery. Patients & methods: Results of EABR and NRT measures performed in the cooperation with neurophysiologist are reviewed. During the years 2002 to 2006 42 children received Nucleus implant which allows NRT measurment. There were 17 boys and 25 girls, aged 8 month to 14 years. Results: EABR were recorded in 52% of tested patients, responses were mostly unilateral (91%). NRT reviewed a stimulable auditory nerve in 86% of tested patients. Conclusions: EABR provide the clinician with a valuble tool for selecting the most appropriate ear for implantation. NRT provide informations for the initial fitting of the speech processor especially in small children who are unable to cooperate during the fitting. The results of this measurment are especially valuble in cases where stapedius reflex during surgery is absent. NRT also provide reassurance that the implant is functioning and enable us the follow up of auditory nerve respons changes during rehabilitation.
