Summary
Cochlear implantation (CI) in children with cochlear aplasia can lead to good speech perception. Pre-operative audiological testing is crucial for successful outcomes in these cases.
Area of Science:
- Otolaryngology
- Pediatric Audiology
- Neurosurgery
Background:
- Cochlear aplasia presents unique challenges for hearing restoration.
- Cochlear implantation (CI) is a potential treatment for hearing loss in children with cochlear malformations.
Observation:
- This study evaluated the surgical outcomes of CI in pediatric patients diagnosed with cochlear aplasia.
- The prevalence of cochlear aplasia among pediatric CI candidates was assessed.
Findings:
- Children with cochlear aplasia represented 0.4% of all pediatric CI cases.
- Preoperative audiological responses and the presence of the auditory nerve (via MRI) were confirmed.
- Successful electrode array insertion into the vestibule was achieved, with clear neural responses post-implantation.
- Significant improvements in hearing thresholds (to 25 dB HL) and open-set speech perception were observed.
Implications:
- CI is a viable option for improving speech perception in children with cochlear aplasia.
- Thorough preoperative audiological and imaging assessments are essential for surgical planning and success.
- Vestibular electrode insertion can yield favorable functional outcomes.
