Summary
Sequential bilateral cochlear implantation (BiCI) in children with cochlear nerve deficiency (CND) leads to significant long-term auditory and speech improvements. Some children even show enhanced speech perception with bilateral devices, suggesting BiCI is a viable option for selected CND patients.
Area of Science:
- Otolaryngology
- Neuroscience
- Pediatric audiology
Background:
- Cochlear nerve deficiency (CND) presents unique challenges for auditory rehabilitation.
- Sequential bilateral cochlear implantation (BiCI) is a therapeutic approach for CND.
- Long-term outcomes of BiCI in CND pediatric populations require further investigation.
Purpose of the Study:
- To evaluate the long-term auditory and speech development in children with CND following sequential BiCI.
- To assess the efficacy of BiCI in improving speech recognition and auditory performance in this cohort.
Main Methods:
- Retrospective review of 16 children with CND who received sequential BiCI.
- Auditory and speech abilities assessed using validated scales (CAP, IT-MAIS, SIR).
- Measurement of closed-set and open-set speech recognition before and after contralateral implantation.
Main Results:
- Continuous auditory and speech progress observed post-implantation.
- Improved closed-set speech recognition in all nine assessed patients after contralateral CI.
- Four patients achieved >90% on closed-set tests; two demonstrated bilateral benefit.
Conclusions:
- Sequential BiCI yields favorable long-term auditory and speech outcomes in children with CND.
- Some CND children experience enhanced speech perception with bilateral cochlear implants.
- BiCI is a potentially effective option for carefully selected pediatric CND cases.
