Overview

Long-term resilience of neural responses shows stability in cochlear implants, suggesting fewer reprogramming needs.

Key Points

  • This research aims to investigate the long-term stability of neural responses and stimulation levels in children with cochlear implants.
  • Analyzed data from 664 bilaterally implanted children with a total of 1,291 devices.
  • Evaluated stimulation parameters and electrophysiological thresholds over a follow-up period from 2003 to 2022.
  • Measured changes in auditory nerve thresholds and slopes of amplitude growth functions.
  • Stimulation parameters stabilized within 12 months for 75.3% of devices at C-levels and 75.4% at T-levels.
  • Electrophysiological changes per year were minimal, with thresholds showing a mean change of 0.35 CU/year.
  • Older age at implantation correlated with decreased stimulation levels before reaching a plateau.
