Sudden airway obstruction due to pedunculated laryngeal polyps.

Acute upper airway obstruction from laryngeal polyps is uncommon. However, a large pedunculated laryngeal polyp, when unrecognized, may produce sudden airway obstruction. The importance of an early diagnosis and treatment is stressed. Primary care physicians, endoscopists, anesthesiologists, and otolaryngologists should be aware of this condition and add it to their differential diagnosis of sudden respiratory obstruction.
