Eight cases of giant cholesteatoma of petrous bone invading labyrinthine and facial nerve canal were reported. There were 4 cases of facial paralysis or total paralysis, 4 cases of conductive deafness, 2 cases of sensory deafness and 2 cases of mixed deafness. 8 cases were carried out temporal bone CT, MRI and other tests. From the way of encroachment of cholesteatoma, there were 4 cases who lost their way and 2 cases lost their way after getting lost. From the site of invasion, 2 cases invaded the petrous apex, 6 cases inflated the semicircular canal, 5 cases damaged the cochlea, 4 cases involved the facial nerve canal labyrinth and 4 cases extended to the internal auditory canal. Eight cases of cholesteatoma were treated surgically, but no facial nerve repair. There were 7 cases of deafness after operation, 5 cases of facial paralysis, 5 cases of facial paralysis were later recovered facial function, no case of intracranial complications and death.
