Bèkèsy audiometry in evaluation of hearing in cases of raised intracranial pressure

Abstract

The paper reports findings in a Bèkèsy audiometry study on 50 ears of 27 patients with raised intracranial pressure. The B èkèsy audiometry was done both preoperatively and after operation when the raised intracranial pressure had been controlled. The study showed a significant hearing loss in Bèkèsy audiometry due to raised intracranial pressure. However, only low frequencies of 125-250-500 Hz showed a reversal of hearing loss which was statistically significant. The type II pattern of Bèk èsy audiometry changed to type I after control of the raised intracranial pressure. The type IV and V patterns had a tendency to change to Bèk èsy I or II, on control of the raised intracranial pressure.
