The difficult management of patients with respiratory segmental dystonia.

UNLABELLED Respiratory dystonia is a rare and difficult to diagnose disorder, that causes breathing restriction of various degrees. The objective of the study is to report the case of a patient with respiratory dystonia involving the larynx and the pharynx and its evolution concerning spasms intensity and control. CASE REPORT A 24 year-old-man has been followed for 5 years. The diagnosis was made by means of nasofibroscopy and electromyography. Treatment was carried out with laryngeal and pharyngeal Botulin toxin injections, as it became necessary for symptoms control. CONCLUSION The difficult management can be secondary to the lack of knowledge on the etiology and physiopathology of the impairment, and because of the limitations in the treatment of associated respiratory symptoms.
