Two cases of giant hemangioma of oral region treated by transcatheter embolization are reported in this article.<BR>Case one was a 2I-year-old female visited our hospital complaining of swelling of the tongue and oral floor. External carotid angiography showed a vascular lesion mostly fed by the bilateral facial arteries, and showed clear tumor stain. Transcatheter embolization using Ivalon® was carried out with digital subtraction angiography. After embolization the tumor stain and the distal parts of main feeders were not visualized on angiography, and then the tumor size was decreased clearly.<BR>Case two was a 25-year-old man, who came to our hospital complaining of speech disturbance due to swelling of the tongue. ECAG showed a vascular lesion fed by the left lingual artery, but tumor stain was not visualized. We tried transcatheter embolization without excising the tumor, taking into consideration of the functional aspects. After embolization, the distal part of the main feeder was not demonstrated. After treatment, a considerable decrease in the size of the lesion was observed.<BR>From these experiences, it was considered that embolization was one of treatment methods of the hemangioma of oral and maxillofacial regions, and that angiography gave many informations about its indication and effect.
