The Food and Drug Administration approved cochlear implants for adults in 1985 and children have been getting them since 1990. By 2010 more than 42,000 people in the country had them, the FDA estimates, about 28,000 of them children. Zachary Duick was one of them -- and Greater Baltimore Medical Center's first patient to have implants placed in both ears. The Duick's second son, Ethan, was also born deaf and had surgery for the implants when he was a year old. Of the 35 double-implants GBMC has performed, two were for the Duick family.
