Laryngeal granuloma is an uncommon complication arising from irritation of the laryngeal structures. We present a case where bilateral laryngeal granulomas became clinically evident 3 mo after orthognathic surgery. The patient, a 19-yr-old female, developed acute dyspnea after experiencing gradual voice loss. Excision of the lesions under endotracheal general anesthesia led to an uneventful outcome. The causes, predisposing factors, diagnostic features, and treatment of laryngeal granuloma are reviewed.
