Arteriovenous malformation (AVM) of the oral and maxillofacial region is considered a rare disease. We report a case of AVM extending from the upper third molar region to the left maxillary sinus, diagnosed on hemorrhage after tooth extraction. The patient was a 27-year-old man referred to our hospital to undergo extraction of the left upper third molar.We performed an emergency operation to achieve hemostasis of abnormal bleeding after tooth extraction. After hemostasis we examined the left maxillary region by computed tomographic (CT) -angiography and magnetic resonance imaging (MRI). An AVM extending from the upper third molar region to the left maxillary sinus was found on CT-angiography anf MRI. We could not perform embolization because the patient was allergic to contrast media. We performed surgical resection using Seiffert's method. No recurrence developed during 8 years of follow-up. Care should be exercised during daily minor surgery such as tooth extraction because serious and abnormal bleeding similar to that in the present case may occur.
