Airway-obstructing epiglottic cyst.

Laryngeal cysts, particularly epiglottic cysts, are generally benign lesions which cause mild dysphagia or hoarseness. We report a case of an epiglottic cyst that caused almost complete airway obstruction. A 43-year-old man presented with progressive dysphagia, hoarseness, and airway obstruction secondary to a large cystic mass involving the entire epiglottis and filling the hypopharynx. He required emergency tracheotomy to secure the airway, and the cyst was incised and drained. Following a subsequent recurrence, laser excision of the cyst was performed and the problem resolved. The cystic mass was found to fill the valleculae, and involved the lingual and laryngeal surfaces of the epiglottis and the left false vocal cord. A review of laryngeal cysts is presented with emphasis on anatomic and embryologic considerations. The potential lethal nature of these lesions is emphasized.
