Objective: To assess cochlear implant (CI) sound processor usage over time in children with single-sided deafness (SSD) and identify factors influencing device use.
Study design: Retrospective, chart review study.
Setting: Pediatric tertiary referral center.
Patients: Children with SSD who received CI between 2014 and 2020.
Outcome measure: Primary outcome was average daily CI sound processor usage over follow-up.
Results: Fifteen children with SSD who underwent CI surgery were categorized based on age of diagnosis and surgery timing. Over an average of 4.3-year follow-up, patients averaged 4.6 hours/day of CI usage. Declining usage trends were noted over time, with the first 2 years postactivation showing higher rates. No significant usage differences emerged based on age, surgery timing, or hearing loss etiology.
Conclusions: Long-term usage decline necessitates further research into barriers and enablers for continued CI use in pediatric SSD cases.
