Long-Term Cochlear Implant Sound Processor Usage in Children with Single-Sided Deafness.

Area of Science:

• Pediatric audiology
• Neuroscience
• Otolaryngology

Background:

• Single-sided deafness (SSD) presents unique challenges in pediatric hearing rehabilitation.
• Cochlear implantation (CI) is an option for children with SSD, but device usage patterns require investigation.

Purpose of the Study:

• To evaluate the long-term daily sound processor usage of cochlear implants (CIs) in children diagnosed with single-sided deafness (SSD).
• To identify potential factors influencing the duration and consistency of CI device utilization in this pediatric population.

Main Methods:

• A retrospective chart review was conducted at a pediatric tertiary referral center.
• Data from fifteen children with SSD who received a CI between 2014 and 2020 were analyzed.
• Average daily CI sound processor usage over follow-up was the primary outcome measure.

Main Results:

• Over an average follow-up of 4.3 years, children averaged 4.6 hours of daily CI usage.
• A trend of declining CI usage was observed over time, with higher usage in the initial two years post-activation.
• No significant differences in usage were found based on age at diagnosis, timing of surgery, or the cause of hearing loss.

Conclusions:

• The observed decline in long-term cochlear implant usage in pediatric SSD cases highlights a need for further investigation.
• Identifying barriers and facilitators for sustained CI use is crucial for optimizing auditory rehabilitation outcomes in children with SSD.
