Abstract: Non-syndromic congenital hearing loss is a global problem. It is the most common disorder at birth, occurring in 1 - 2 /1000 newborns. Congenital hearing loss leads to delayed language development, impaired psychosocial interactions abnormal behavior and poor educational achievement. Genetic transmission is implicated in 50% of the cases of congenital deafness. Of these, about 70 % are non-syndromic. Genetic counseling is essential to making the parents aware of the most appropriate treatment. Classification and the rationale for screening of hearing loss in the newborn will be reviewed here.
