Results of ABR in patients with acustic neurinoma
Journal Title: Polski Przegląd Otorynolaryngologiczny - Year 2015, Vol 4, Issue 2
Abstract
Acoustic neuromas comprise about 6% of all intracranial tumors, about 30% of brainstem tumors, and about 85% of tumors in the region of the cerebellopontine angle. Another 10% are meningiomas. Between 2,000 and 3,000 cases of acoustic neuromas are newly diagnosed each year. The aim of this study was to compare the clinical results of ABRs and the size of acoustic neuroma. This article was based on the analysis of the clinical data of 97 patients with acoustic neuroma confirmed by MRI. We divided patients into 3 groups depending on the stage of the tumor. The ABR responses of the groups of patients were retrospectively considered and compared. Designated objective criteria according to electrophysiological methods are determination of intervals I-V and III-V that are most probable to diagnose acoustic neuroma.
