  The UNC Cochlear Implant Program at the University of North Carolina at Chapel Hill is one of the largest and experienced cochlear implant programs in the country. The number of patients implanted annually continues to rise as a result of expanding candidacy criteria for implantation, new developments in cutting-edge cochlear implant technology, and innovative research projects. Approximately 350 cochlear implant devices are implanted each year at UNC to patients young and old. The pediatric team is committed to providing clinical and therapeutic support to a diverse pediatric patient population. The adult team in collaboration with UNC Health Care serves our adult cochlear implant patients. The UNC Cochlear implant Program incorporates a knowledgeable and sophisticated team of scientists and healthcare professionals.
