Clinical severity ranges from mild dysphonia to acute airway compromise. We report a 51\u2010year\u2010old man with a sore throat, dysphagia, and dyspnea. Flexible laryngoscopy and contrast\u2010enhanced CT revealed an internal pyolaryngocele. After emergency tracheostomy and intravenous antibiotics, the patient underwent CO\n                    <jats:sub>2<\/jats:sub>\n                    laser microlaryngoscopic excision and marsupialization.
