Early cochlear implantation for children with single sided deafness

Area of Science:

• Pediatric audiology
• Neuroscience
• Otolaryngology

Background:

• Single-sided deafness (SSD) in children impacts language, education, and social development.
• Cochlear implants (CI) are the only option for binaural hearing restoration.
• Current US FDA approval for pediatric CI in SSD is limited to children over age five.

Purpose of the Study:

• To evaluate speech perception outcomes in children with SSD implanted at age five or younger.
• To determine the influence of implantation age, deafness duration, etiology, and comorbidities on CI outcomes.
• To assess device usage patterns in young children with SSD.

Main Methods:

• Retrospective chart review of 18 children implanted with CI at age five or younger.
• Analysis of demographic data and speech perception results.
• Examination of factors influencing device usage and audiological outcomes.

Main Results:

• Speech perception outcomes were highly variable, ranging from significant benefit to no sound awareness.
• Age at implantation and duration of deafness did not show a clear impact on results.
• Low device usage was observed, particularly in children with anatomical abnormalities like a hypoplastic cochlear nerve.
• Challenges exist in assessing speech perception in young children, with a lack of standardized measures.

Conclusions:

• Early CI implantation for pediatric SSD may offer speech perception benefits, but success is not universal.
• Candidacy evaluation requires a comprehensive approach, including medical, audiological, family support, and realistic expectations.
• Particular caution is advised for children with significant anatomical anomalies.
