Unilateral sensorineural hearing loss in children.

The authors present a report of 280 cases of unilateral sensorineural hearing loss (U.H.L.) in children, observed from 1979 to 1986 in the Bambino Gesu' Hospital in Rome. Only 23.2% of these hearing impairments were due to a known etiology (mainly mumps infection). In the majority of the cases (79.3%) the hearing loss was profound. The authors discuss the methods for the etiological diagnosis and the possibility of prophylaxis both of U.H.L. and of communication difficulties.
