[Possibility of hearing preservation treatment by patient suffered from neurofibromatosis type 2: case report].

The main tumor of cerebellopontine angle are vestibular schwannoma (80-90%). Most of them are unilateral lesion but 5% of them are bilateral pathological mass. There are genetic disease like neurofibromatosis type 1 and 2. According to National Institute of Heath Consensus Development Conference the best treatment method is microsurgery.
