Abordaje retrosigmodeo transmeatal para schwannomas vestibulares. It cegebelosa a variable course, passing backward to be distributed to the anterior part of the undersurface of the cerebellum, anastomosing with both the posterior inferior cerebellar PICA arteriw of the vertebral artery and the superior cerebellar artery. However, the anterior inferior cerebellar artery AICA usually runs adjacent to internal auditory canal nerves, and its course may severely impede total tumor resection.
