[Gentamycin as a cause of hearing impairment in children treated at the Phoniatric Outpatient Clinic in Zabrze between 1987-1992].

Medical history was analyzed in an attempt to identify the etiology of 748 hard-of-hearing children treated at the Phoniatric Out-Patient Clinic in Zabrze between 1987-1992. In 198 cases, gentamicin was the major cause of bilateral sensorineural hearing loss. Ninety children had a hearing loss of less than 60 dB and 108 above 60 dB. The results obtained in our study are comparable to those of other authors.
