[Otoneurologic findings in multiple sclerosis. Stapedius reflex, vestibular evaluation, early acoustic evoked potentials].

Symptoms such as tinnitus, hearing and taste disorders and facial palsy seldom occur in multiple sclerosis. Although ENT symptoms are few, vestibular and acoustic stapedius reflex tests combined with brainstem auditory evoked potentials (BAEPs) are available, and may give very useful evidence of the existence of MS. 52 patients with definite MS, and 13 patients with probable MS were examined (classified according to the McAlpine criteria). The vestibular and acoustic stapedius reflex tests were abnormal in 51%/61% and 61%/53% respectively of both groups. The corresponding figures for BAEP were 69% and 63%. The combination of the three tests on all patients showed at least one pathological finding.
