Arteriovenous malformation(AVM)rarely occurs in the head and neck region as compared withother sites . In the oral and maxillofacial region, most cases of AVM, including hemangiomas, occur in soft tissue and rarely arise in the jaw. Embolization is currently used as a safer treatment method for mandibular AVM because profuse intraoperative bleeding can occur with traditional surgical procedures.<br>We report favorable results obtained after conducting a 9-year follow-up study of a 14-year-old boy who underwent embolization for AVM that occurred from the buccal region to the body of the mandible. Abnormal bleeding developed after extraction of the right second premolar at a dental clinic, and the patient was referred to our department, where he underwent pressure hemostasis. As CT and MRI confirmed AVM from the buccal region to the mandible, we performed polyvinyl alcohol embolization of the main nutrient artery, as well as direct coil embolization of the varix. Subsequently, after 9 years of follow-up, blood flow has decreased, with no recurrence.
