Cochlear Implantation in Infants and Toddlers With Single-Sided Deafness
University of North Carolina, Chapel Hill
Summary
The goal of this clinical trial is to investigate the safety and effectiveness of cochlear implantation in infants and toddlers with single-sided deafness. The main questions it aims to answer are: * Are cochlear implants an effective treatment of single-sided deafness in infants and toddlers? * Are cochlear implants a safe treatment for single-sided deafness in infants and toddlers? Participants will receive a cochlear implant and be followed until they are five years old. During those five years, the investigators will program the device and monitor auditory development. Children will be asked to: * Undergo cochlear implantation * Wear their cochlear implant processor whenever they are awake. * Participate in traditional hearing tests * Participate in traditional hearing testing * Participate in localization testing * Participate in hearing in noise testing * Participate in word recognition testing * Participate in speech, language, and educational evaluations The researchers will compare results to children with typical hearing in both ears and children with single-sided deafness who have not received an implant to observe any differences between the groups.
Description
Cochlear implantation is an FDA-approved option for children with single-sided deafness (SSD) who are over the age of five years. It has been well established that early implantation is advantageous for children with bilateral hearing loss as it takes advantage of the narrow window of neural plasticity. Research has yet to show the ideal age for implantation in children with SSD but considering the known impacts of age at implantation and duration of deafness on cochlear implant (CI) outcomes, five years is likely a late age for implantation in a child with congenital SSD. The purpose of this…
