Children with SSD who qualify will receive a MED-EL SYNCHRONY 2 implant and two speech processors between the ages of 7 months and 2 years 11 months.​You and your child will be asked to come to our labs in North Carolina for regular follow-up until your child turns five. In the first year, we will see you 9-10 times including screening and surgery. After the first year we will ask you to come see us twice a year until the age of five. All of these visits will be covered by the study. The study does not cover travel and lodging. ​To qualify your child must:​
