[Acute bilateral recurrent laryngeal nerve paralysis, a symptom of Shy-Drager syndrome].

The Shy-Drager syndrome causes symptoms of multiple nervous atrophy and orthostatic hypotension. This rare disease was diagnosed in a 40-year-old man after he developed an acute bilateral vocal fold paresis. The respiratory failure required an immediate tracheotomy. The Shy-Drager syndrome can include cranial nerve lesions. It should be taken into account in differential diagnosis in ENT diagnoses.
