Multifrequency impedance measurement and Meniere's disease. Analysis of the results of TEFLAG

摘要

We present today our preliminary results of the TEFLAG test performed on 58 patients suffering from Meniere's disease. This test completed in 1993 has already led to a 4-stage classi- Fication of noise induced hearing losses. On the one hand, it is Based on the morphological study of susceptance B curves, and On the other hand, on the study of the resonant frequency (RF) Of the annular ligament of the stapes, provided by a multi- Frequential impedancemeter. The endolymphatic hydrops Coming with the Meniere's disease practically always cohabits In the intercritical period with the decrease of the perilymphatic Pressure of the scala vestibuli, wich is shown in the morphology Of Stage IV curves especially, and the decrease of the annular Ligament rigidity.
