Newborn hearing screening has been considered a valuable addition to newborn care over the last decade. The earlier children with hearing loss can be identified, experts say, the sooner they can begin therapies to learn sign language or be evaluated for cochlear implants.
However, a new study shows that many children pass the screening test only to be diagnosed as hearing-impaired later on. The study, published Monday in the Archives of Otolaryngology -- Head & Neck Surgery, found that one-third of children who later received cochlear implants initially passed the newborn screening test. It appears that some children have a delayed onset of hearing loss that stems from the inner ear or central processing centers of the brain. This type of loss is not detected immediately after birth.
