ABSTRACT

Vestibular schwannoma is a slow-growing benign tumor that develops in the vestibulocochlear nerve. It was first described by E. Sandifort in 1777. It affects 1 per 100,000 people, is more frequent between the fourth and sixth decade of life, occupies between 80 and 90% of all tumors of the cerebellopontine angle. In cases of bilateral schwannomas, its prevalence ranges from 1: 210,000. In the event that the tumor is presented bilaterally, it is consitence with neurofibromatosis type II.
