Abstract

✓ A case is reported in which the diagnosis of a neurinoma and its growth from the labyrinthine part of the facial nerve were established preoperatively on the basis of functional disturbances of the intermedius nerve and characteristic radiological changes. Specific tests for differential function of the facial nerve are discussed and the relation of the site of origin to symptoms in comparable reported cases analyzed.
