IntroductionThe US Food and Drug Administration (FDA) granted its first approval for cochlear implants (CI) in children with bilateral sensorineural hearing loss (SNHL) in 1990. In 2019, the FDA expanded CI indications to include children with unilateral SNHL. ObjectiveThe aim of this study was to assess the prevalence of children with unilateral SNHL in the population of new pediatric CI recipients between 2012 and 2021. MethodsA retrospective analysis using the American College of Surgeons National Surgical Quality Improvement Pediatric database examined patients under 18 years of age with bilateral or unilateral SNHL who underwent CI between 2012 and 2021. Current Procedural Terminology code 69930 identified patients with ‘cochlear device implantation, with or without mastoidectomy.’ The percentage of children undergoing CI for unilateral versus bilateral SNHL during the study period was calculated and subjected to statistical analysis. Results9863 pediatric CI patients were included with a mean age of 5.1 (95 % CI 5.1–5.2) years at the time of implantation. 7.5 % (N = 739) of patients had unilateral SNHL and 92.5 % (N = 9124) had bilateral SNHL. Children with bilateral SNHL undergoing CI were significantly younger (5.0 years versus 6.9 years for those with unilateral SNHL, p < .001). There was a statistically significant difference in the percentage of children receiving CI for unilateral versus bilateral SNHL (3.3 % in 2012 to 14.3 % in 2021, p < .001) before and after the FDA changes. ConclusionsThe proportion of CIs placed for unilateral SNHL has increased annually even before 2019 when the FDA expanded its CI indications to include children with unilateral SNHL for the first time.
