Summary
Unilateral cochlear implantation (CI) offers a viable treatment for pediatric single-sided deafness (SSD), improving speech perception in quiet and noise. Careful patient selection is key for successful outcomes in children with SSD.
Area of Science:
- Otolaryngology
- Audiology
- Pediatric Medicine
Background:
- Single-sided deafness (SSD) in children presents unique challenges for auditory development and speech perception.
- Unilateral cochlear implantation (CI) is increasingly considered as a therapeutic option for pediatric SSD.
Purpose of the Study:
- To evaluate the outcomes of unilateral cochlear implantation in pediatric patients with single-sided deafness.
- To assess speech perception abilities and device usage in children with SSD post-CI.
Main Methods:
- Retrospective case series of 14 pediatric patients (<18 years) with SSD undergoing unilateral CI.
- Speech perception testing in quiet and noise (CI-only and bimodal conditions) after at least one year of device use.
- Analysis of device usage data logs.
Main Results:
- Mean age at CI was 5.0 years; mean follow-up was 3.4 years.
- Significant improvement in word recognition scores (WRS) in the CI-only condition (mean 56%).
- No negative impact of CI on speech perception in noise; patients performed equally or better with CI-on.
Conclusions:
- Unilateral cochlear implantation is a viable treatment for pediatric SSD in this cohort.
- Successful outcomes include open-set speech and improved performance in background noise.
- Careful patient selection and counseling are crucial for optimal results.
