Your baby did not have a clear response on their hearing screen and has been referred for a more detailed hearing test. The test may show that your baby’s hearing is normal, but it might show that your baby has a hearing loss. In most cases hearing loss in babies is temporary, often as result of blockage in the outer or middle parts of the ear. A small number of babies will be found to have a permanent hearing loss that will affect one or both ears.
There are many causes of permanent hearing loss in babies and young children. Up to 20% of cases are caused by congenital CMV.
