What causes significant hearing loss at birth?
There are several causes of hearing loss at birth. Some are temporary and easily corrected, such as blockage of the ear canal or fluid in the middle ear. Other causes may be more serious and more difficult to treat. Some infections that a mother may have during her pregnancy, such as rubella, may result in a hearing loss at birth. Hearing loss may also be the result of genetic factors. http://www.in.gov/isdh/programs/mch/newbornuniver.
