Para-arytenoid cartilage pseudodiverticulum formation as a sequela of endotracheal intubation.

Context: Laryngotracheal injury secondary to endotracheal intubation results from ischemic necrosis, which develops within hours of intubation, with injury severity increasing with duration of intubation. Postextubation and postmortem observations demonstrate that laryngotracheal injury still occurs in a large number of intubated patients.

Objective: To demonstrate laryngeal injury, specifically pseudodiverticulum formation, as a result of intubation.
