[A case of cholesteatoma extending into the medial petrous bone].
A case of facial nerve palsy caused by cholesteatoma was reported. High-resolution CT was very excellent in delineating the mass extension and bony destruction. The labyrinthine segment of facial canal was thought to be the route of spread of cholesteatoma to the medial petrous bone as this case of poor pneumatized petrous bone.
