BACKGROUND: Cervico-mediastinal hemangiomas in adulthood are rare and slow-growing vascular tumors. The optimal treatment for giant hemangiomas is controversial. In asymptomatic cases, clinical observation is generally recommended. METHODS: We report the transoral resection of a pharyngolaryngeal hemangioma (diameters of 44 × 56 × 39 mm) with tracheal involvement and mediastinal extension. Clinically, the patient had throat foreign body sensation, severe dyspnea and stridor. The hemangioma was first embolized by injecting ethylene-vinyl alcohol copolymer (Onyx) transorally, and then the obstructive aspect of the tumor was resected with a bipolar and ultrasonic clamp (ThunderBeat®, Olympus). RESULTS: Two months after surgery, nasal fiberendoscopy showed complete disappearance of the vascular mass at the larynx and hypopharynx, with a normal mobility of the larynx. CONCLUSION: In symptomatic patients, surgical reduction of large pharyngolaryngeal hemangiomas may be feasible by direct embolization and transoral ultrasonic resection. Both may provide an almost bloodless surgical field. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1239-1242, 2017.
