Phenothiazine induced lingual trauma.

A 34-year-old woman presented with an unusual and unfortunate combination of complications to a phenothiazine drug. Rhythmic protrusion of her tongue was not a problem until it became trapped outside of her oral cavity by spasm of the muscles of mastication. Massive edema with questionable viability of her tongue ensued. She presented as an airway as well as therapeutic management problem.
