[Expansive processes of the cerebellopontile angle. Neuro-otological evaluation of 146 cases].
A group of 146 patients with surgically proved C-P angle tumors were studied in respect of the incidence of the trigemino-facial and cochleo-vestibular signs. The particular purpose of this study was to determine the pertinent signs in the early diagnosis of the C-P angle tumor, its stage and histo-pathologic feature's determination. The principal indices of C-P angle tumor are: Wrisberg nerve dysfunction; neural hearing loss as designed by stapedius reflex study and BERA; unilateral vestibular deficit without true and persistent vertigo, first at all when associated with central vestibular signs. The central vestibular syndrome grade, the trigeminal hyposensitivity and the cophose can perform a correction of the stage estimation in 39% when false estimation has been done. Endly, 7 criteria are proposed which help the histopathologic feature differentiation.
