Insights
Cochlear implants (CI) are appropriate for children with partial hearing (PH) in low frequencies and profound high-frequency loss. Early CI intervention improves outcomes, even with residual hearing, enabling better speech development.
Area of Science:
- Audiology
- Pediatric Otolaryngology
- Biomedical Engineering
Background:
- Children with partial hearing (PH) present unique challenges for cochlear implant (CI) candidacy.
- Existing literature lacks clear clinical criteria and optimal timing for CI implantation in these cases.
Purpose of the Study:
- To evaluate the clinical appropriateness and outcomes of cochlear implantation for children with PH.
- To determine the impact of early high-frequency sound access on developmental potential.
Main Methods:
- Retrospective data analysis from two major UK pediatric audiology centers.
- Comparison of hearing aid versus cochlear implant performance in children with PH.
Main Results:
- Children with PH demonstrate better outcomes with CIs compared to hearing aids.
- Early implantation is crucial for maximizing developmental potential in children with PH.
Conclusions:
- Cochlear implantation is a clinically appropriate and beneficial intervention for children with PH.
- Early access to high-frequency sound via CIs is essential for optimal auditory development and speech potential.
Abstract:
Children who have partial hearing (PH) in the low frequencies and profound sensorineural hearing loss in the high frequencies can present a challenge to cochlear implant (CI) teams in terms of referral, assessment, and candidacy. Neither clinical criteria nor optimal timing for implantation has been explored in the literature. Data from both the Hearing Implant Centres of Birmingham Children's Hospital and St Thomas' Hospital indicate that it is clinically appropriate to implant children with PH; they perform better with CIs than with hearing aids, even if their hearing is not fully preserved. We have also found that children need early access to high frequency sound in order to reach their full potential.
