[Differential diagnosis of vocal cord immobility after intubation]

Vocal cord paralysis as cause of an immobility of the vocal cord following endotracheal intubation is often a misdiagnosis. The differential diagnosis is pointed out to distinguish between paresis and ankylosis of the cricoarytaenoid joint, interarytaenoid fibrosis or luxation of the arytaenoid. The development of these disturbances following endotracheal intubation and their therapy are presented.
