Conclusions
The two most frequent etiologies found in severe/profound hearing loss in children in our area were hereditary and non infectious perinatal problems. Infectious disease were scarce. Will decrease when genetic test were used as clinical basis.

To know the etiology of <dis>preiperlingual bilateral hearing loss</dis> in children.

All the patients diagnosed with <dis>bilateral severe/profound, pre or perilingual hearing loss</dis> at Sierrallana and Marqués de Valdecilla Hospitals (Cantabria, Spain) during the last 20 years were included in this study.
Results

In 21% of cases was not Known.
Conclusions
The two most frequent etiologies found in <dis>severe/profound hearing loss</dis> in children in our area were hereditary and non infectious perinatal problems.
Infectious disease were scarce.
Will decrease when genetic test were used as clinical basis.
