Hearing loss after head injury.

Sixty head injury patients were evaluated for hearing loss; ten underwent ABER testing. Forty percent of the cases had hearing loss of different degrees. The audiometric pattern was variable in the different types of injuries, although the incidence of conductive deafness was quite low (5%). In most of the cases of sensorineural hearing loss, the end organ was implicated. Recruitment was demonstrated in the ABERs, as well as in the retrocochlear lesions, by studying the IPLs present.
