Abstract
A battery of audiological tests for sensori-neural disorders was performed on 235 cases with posttraumatic complaints of the head and neck.
The type IV of Békésy audiometry was found most frequently in patients who were unconscious soon after the accident.
A poor speech discrimination in spite of normal hearing for pure tone was found in some cases who had a bruise on the right temporal region.
By analyzing the data from the subjects on whom re-examination was performed, it was known that retrocochlear disorders were often found in patients who revealed a higher pure tone hearing threshold in the second test than the first audiometry.
Many cases with unilateral tinnitus showed positive recruitment. Signs of the retrocóchlear leison were also commonly found in patients with unilateral tinnitus rather than in those with bilateral tinnitus.
