Occasionally, membrane formation and laryngeal ulceration have been reported. Lesions on the vocal cords seem to be rare, but granulomas or ulcerations have been reported, particularly after prolonged tracheal intubation. A few cases of vocal cord paralysis following endotracheal anesthesia have been reported.2-4 The following four case reports illustrate this complication.
