The authors study the different parameters of the stapedius reflex on a 55 patients group with retrocochlear and non tumoral diagnostic is assess by electrophysiologic (BERA, Electrocochleography) and neuroradiologic explorations (TAC), Meato-cisternography, NMR). We realise an comparative study between the results of this group and the results of 2 other groups (98 acoustic neuromas and 104 endocochlear diseases). The test has a moderate sensibility and none specificity in this kind of pathology, because the high percent of false negative (30%), and the positivity on 95% of acoustic neuromas and on 74% of endocochlear diseases.
