A thorough neuro-otologic evaluation is indicated in each case. Ten patients had an acoustic tumor. A vasodilator regimen was prescribed in 380 cases and resulted in hearing improvement in 40%. Favorable… (More)

The persistence of the delayed waves may not reflect structural damage, but rather may still reflect a slowly recovering system.
The preceeding cases were selected to illustrate the contribution of BER audiometry in threshold testing for infants and malingerers, diagnosis of VIIIth nerve tumors, and identification of brainstem lesions. We feel, however, that these represent only the fundamental applications of BER and that a whole new diagnostic dimension wil evolve. The day only… (More)
