Advances in Surgery for Acoustic Neurinoma (A Synopsis)

Abstract

Radical surgery has always been the ultimate objective of any operative treatment in cases of acoustic neurinomas. The degree of radicality obtainable depends on various factors, including the size and localization of the tumor and, more prominently, its orientation and relationship to adjoining structures, particularly the brainstem. But the obtainable radicality is decided by the surgical technique, the choice of a suitable anesthesia, an optimal view of the surgical field and an optimal access to the tumor by appropriate positioning of the patient. We should like to report on some modalities developed in the Vienna clinic for the purpose of advancing the radicality of acoustic neurinoma surgery.
