Abstract
Arteriovenous malformation (AVM) of the jaws are considered to be rare lesions. A 26-year-old woman was referred to our hospital because of right mandibule profuse swelling. Radiography showed the irregular radiolucency extending from the right first premolar region to the right condyle. In angiography, wide AVM was founded. Embolization of right external carotid artery and lingual artery was performed to decrease the hemorrhage during operation on Cyanoacryrate. At 2 weeks after the embolization, the operation was performed under nasoendtracheal general anesthesia. Hemimandibulectomy and enucleation of the tumor was by extraoral approach. The hemorrhage was uncontroled and reached 3, 035 ml. Postoperatively anaerobic infection occurred, and controlled by antibiotics and removal of the reconstructed plate. The pathological diagnosis was AVM.
