Electrically evoked compound action potentials (ECAPs) represent summation of action potentials generated by neurons of the auditory nerve in response to electrical stimulation. The slope of the ECAP amplitude growth function (AGF) reflects responsiveness or survival of neurons proximal to the stimulating electrode....
ECAP-based monitoring of neural responsiveness dynamics in pediatric CI users shows promise as an objective tool for tracking auditory nerve health, but clinical protocols based on these dynamics are not yet established; no immediate practice change is warranted.
Understanding how auditory nerve responses change over time in pediatric CI users could lead to better, more personalised programming strategies and earlier identification of poor neural health.
- 01Investigated electrically evoked compound action potentials (ECAPs) as a marker of auditory nerve responsiveness in children with cochlear implants.
- 02Focused on dynamic (time-varying) aspects of neural responsiveness, not just a single measurement.
- 03Published in European Archives of Otorhinolaryngology (doi: 10.1007/s00405-026-10449-9).
- 04ECAP measures are increasingly used in clinical CI programming and outcome prediction.
- 05Pediatric-specific data on neural dynamics are relatively scarce, making this work novel.
ECAPs reflect dynamic changes in auditory nerve neural responsiveness in pediatric cochlear implant users.
