The use of the operating microscope for modification of the classical suboccipital removal of cerebellopontine angle tumors has now advanced to the point where acoustic neurinomas, from the small intracanalicular lesions to the more common giant tumors may be most reasonably resected by this technique. At the Neurosurgical Department in Vienna, 24 cases of acoustic neurinomas have been subjected to microsurgery since 1971. In 20 cases we were dealing with unilateral neurinomas, while multiple tumors consistent with von Recklinghausen’s disease were found in the cerebellopontine angle bilaterally in 4 patients. In 20 cases the angle tumor measured more than 4 cm in diameter, only in 4 patients were we dealing with 2 to 3 cm tumors. |
