[Facial nerve neurinoma masked by otosclerosis (author's transl)]

A case of operation for presumed otosclerosis. Discovery of a neurinoma between the branches of the stapes probably originating from the geniculate. Facial paralysis was not present either before or after the operation which, in fact, was only partial (a more extensive operation was refused later on). A curious F.P. "to cold", 30 years beforehand, recovered without sequelae.
