title: Analysis of electrically evoked compound action potential of the auditory nerve in children with bilateral cochlear implants.
abstract: BACKGROUND
  The cochlear implant device has the capacity to measure the electrically evoked compound action potential of the auditory nerve. The neural response telemetry is used in order to measure the electrically evoked compound action potential of the auditory nerve.
  
  
  OBJECTIVE
  To analyze the electrically evoked compound action potential, through the neural response telemetry, in children with bilateral cochlear implants.
  
  
  METHODS
  This is an analytical, prospective, longitudinal, historical cohort study. Six children, aged 1-4 years, with bilateral cochlear implant were assessed at five different intervals during their first year of cochlear implant use.
  
  
  RESULTS
  There were significant differences in follow-up time (p=0.0082) and electrode position (p=0.0019) in the T-NRT measure. There was a significant difference in the interaction between time of follow-up and electrode position (p=0.0143) when measuring the N1-P1 wave amplitude between the three electrodes at each time of follow-up.
  
  
  CONCLUSIONS
  The electrically evoked compound action potential measurement using neural response telemetry in children with bilateral cochlear implants during the first year of follow-up was effective in demonstrating the synchronized bilateral development of the peripheral auditory pathways in the studied population.
