[Temporary total deafness in disseminated encephalomyelitis (author's transl)].

Total deafness, which recovered, in an 18 year old woman with disseminated encephalomyelitis is reported. The deafness involved the left ear, but vestibular abnormalities were demonstrated bilaterally. After some weeks both auditory and vestibular responses returned to normal but nearly 2 years later a temporary left ear hearing loss of 30 dB and a spontaneous nystagmus occurred.
