The purpose of this investigation is to demonstrate the safety and effectiveness of MED-EL cochlear implants in children 7 months to 5 years, 11 months of age who fall outside the current FDA-approved candidacy criteria and, yet, continue to demonstrate insufficient functional access to sound with appropriately fit hearing aids and aural habilitation.
