[Facial nerve tumors: three cases (author's transl)].

The first one is a neurofibroma associated with a Charcot-Marie Tooth's disease involving all the tympanic segment of the facial nerve: extirpation and graft. Improvement of facial motricity to 42%. The second one is a small Schwannoma lateral to tympanic segment: extirpation without paralysis. The third is a large Schawannoma of the tympanic mastoïd segments involving the facial nerve to its division in the parotid gland, and with a limited extension in the cerebello-pontine angle. Extirpation and graft. Discussion and recent bibliography.
