    Abstract:
    In cases of severe hearing loss in babies an early rehabilitation should prevent a delay in development. More than a half of all hearing disorders in children are acquired; to a large extend these hearing disorders are caused by premature birth and can be detected by suitable screening. Two methods are used for testing: (1) reflex audiometry with a standardized stimulus generator; and (2) bedside recording of brainstem potentials. Having tested the method of bedside recording of brainstem potentials a group of 60 premature infants of varied body weights and no additional diseases was examined as "normal" control group. Only premature birth with all signs of maturation adequate for gestational age is not a greater risk for hearing disorders. In premature infants with birth weights less than 1500 g, having marked hyperbilirubinemia and extensive intracranial bleeding always increased wave V latencies has been observed. In about 10% of these children severe hearing disorders were diagnosed and after leaving the premature department were sent to a paedaudiological dispensaire.
