The transotic approach to the cerebellopontine angle has been developed at the University of Zurich for the removal of acoustic tumors in an effort to increase operative exposure and enhance facial nerve preservation and reconstruction. Key steps involve the total removal of all pneumatic cell tracts with middle ear and eustachian tube obliteration, followed by complete otic capsule removal for tumor exposure. This article discusses the advantages, disadvantages, and technique of this approach.

UI	MeSH Term	Description	Entries
D009464	Neuroma, Acoustic	A benign SCHWANNOMA of the eighth cranial nerve (VESTIBULOCOCHLEAR NERVE), mostly arising from the vestibular branch (VESTIBULAR NERVE) during the fifth or sixth decade of life. Clinical manifestations include HEARING LOSS; HEADACHE; VERTIGO; TINNITUS; and FACIAL PAIN. Bilateral acoustic neuromas are associated with NEUROFIBROMATOSIS 2.

D002528	Cerebellar Neoplasms	Primary or metastatic neoplasms of the CEREBELLUM. Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs.
