Summary
Intraoperative electrically evoked stapedius reflex thresholds (eSRTs) in pediatric cochlear implant users did not correlate with postoperative measurements. These findings suggest intraoperative eSRTs cannot predict early outcomes after cochlear implantation.
Area of Science:
- Audiology
- Neurosurgery
- Biomedical Engineering
Background:
- Cochlear implants (CIs) are vital for pediatric hearing restoration.
- Electrically evoked stapedius reflex thresholds (eSRTs) assess auditory nerve function.
- Predicting postoperative CI outcomes is crucial for managing pediatric patients.
Purpose of the Study:
- To investigate the correlation between intraoperative and postoperative eSRTs in children with CIs.
- To determine if intraoperative eSRTs can predict early postoperative auditory nerve function.
Main Methods:
- Sixty-five pediatric CI users with congenital prelingual hearing loss were studied.
- Intraoperative and postoperative eSRTs were measured using CI electrodes.
- Paired-sample t-tests analyzed the correlation between intra- and postoperative eSRTs.
Main Results:
- A statistically significant difference was found between intraoperative and postoperative eSRTs.
- No significant correlation was identified between intraoperative and postoperative eSRTs.
Conclusions:
- Intraoperative eSRT measurements are not predictive of early postoperative eSRTs in pediatric CI users.
- Clinical decisions should not solely rely on intraoperative eSRT values.
