L’audiometria multifrequenziale nello studio degli acufeni

Abstract

Multifrequency audiometry, using 20 Hz steps between 125 Hz to 800 Hz, studies patients affected by essential tinnitus. Bilateral normal auditive perception, tested using standard audiometers, was not confirmed in all patients analysed using the multifrequency technique. We observed neurosensorial deficit areas between 1040-1100 Hz and between 1920-1960 Hz. These results were integrated with diagnostic imaging and tested coclear nucleus microiscaemic areas and endococlear suffering. The patients who were given medical treatment showed benefits which were confirmed by partial regression of the neurosensorial deficit and tinnitus.
