A case of laryngeal stridor in an adult patient is presented and the diagnose of syndrome of Shy-Drager is proposed. This syndrome is the result of a degeneration of the central nervous system. Some autonomic functions are involved in this process. The leading symptoms are an orthostatic hypotension, parkinson-like symptoms and laryngeal stridor. The last symptom results from a neurogenic paralysis of both posterior crico-arytenoideus muscles. A depletion of neurotransmitters in the central nervous system would be the cause of the syndrome. The treatment is symptomatic. Concerning the laryngeal stridor, tracheotomy, eventually followed by a crico-arytenoidopexy, is the only treatment which can be proposed.
