Summary
Live-aided Cortical Auditory Evoked Potentials (CAEP) successfully optimize cochlear implant programming in children. This method streamlines audiology appointments by potentially reducing programming time and trial runs.
Area of Science:
- Audiology
- Neuroscience
- Biomedical Engineering
Background:
- Cochlear implants (CI) are crucial for hearing restoration in children.
- Optimizing the most comfortable listening level (M-level) is vital for effective CI use.
- Cortical Auditory Evoked Potentials (CAEP) offer an objective measure for audiological assessment.
Purpose of the Study:
- To evaluate the effectiveness of live-aided CAEP in optimizing M-levels for pediatric CI users.
- To assess if live-aided CAEP programming improves audiological outcomes compared to traditional methods.
Main Methods:
- 14 children (4-8 years) using CI participated.
- Live-aided CAEP was recorded in free-field while adjusting CI programming parameters.
- M-levels were determined by eliciting the P1 peak for specific speech stimuli.
- Outcomes were compared to participants' everyday CI programs after a two-week trial.
Main Results:
- Sound field thresholds showed non-significant improvement with live-aided CAEP programming.
- Speech perception scores were comparable between the new and everyday programs.
- M-levels were slightly higher in the live-aided CAEP program, but not statistically significant.
Conclusions:
- Live-aided CAEP is a viable method for optimizing CI programming parameters.
- This technique has the potential to reduce the number and duration of audiology programming sessions.
