[The rising rate of complementary examinations in suspected neurinoma of the VIIIth cranial nerve (author's transl)].
E.N.T. specialists are obsessed by the diagnosis of neurinoma of the VIIIth cranial nerve. Yet none of the conventional otological or radiological examinations is entirely reliable. In a major centre all otological and radiological investigations can be carried out systematically, but diagnosing the disease with a minimum of examinations is important, would it only be to decide which patients should be referred to the neuroradiologist. Complementary otological and neuroradiological explorations are therefore requested in ever increasing number on the basis of initial symptoms and results of the first examination. Among exploratory methods, CT with injection of air occupies a prominent place as it enables neurinomas located inside the internal auditory canal to be diagnosed at an early stage.
