Objectives: In view of the development of more sensible devices and with bigger relation signal/noise for the diagnosis of alterations in the electrophysiology of the hearing, the evoked potential auditory of brainstem (PEATE) was compared with the magnetic nuclear resonance (RNM) in the diagnosis of neurinome of VIII the cranial pair. Material and Methods: The PEATE and RNM for diagnosis of sensorineural dyacusis and/or humming in the period of July of 2010 had been reviewed handbooks of 108 submitted patients to June of 2011. Having the RNM with examination standard gold, sensitivity (s), specificity (e) and positive predictive value had been calculated (VPP) and negative (VPN) for the PEATE in the research of neurinome of VIII the cranial pair. Results: the PEATE presented S= 100%, and =90.6%, VPP=38.5% and VPN= 100%. Conclusions: the PEATE revealed highly sensible and moderately specific in the neurinome diagnosis. The high VPN becomes possible to lock up the inquiry for neurinome in those patients with normal PEATE.
