109 deaf children were studied prospectively, in a special school, with an interdisciplinary focus. Clinical and audiologic studies were performed on several members of the family, in the first degree, of outstanding cases. 48 cases (44%) were identified as being of genetic etiology, 20 were acquired cases of deafness and 41 cases lacked sufficient data to reach an etiologic diagnosis.
