The objetive of this paper is to expose our experience in the surgical treatment of an arteriovenous fistulae of the lower lip in 15 years- old patien, caused for humanbite. The patient was first diagnosed as traumatic hemangioma, treated with steroids and surgical removal. Four years later a voluminous tumor appeared, a dissection of the external carotid and a carotid angiography was performed and an arteriovenous fistulae was diagnosed. A ligament of the facial and venous vasseles was performed to isolete them from circulation. 4cc of Betametaza were inyected inside of tumors, and later 4 additional doses with 3 week of interval. Three months after the ligament a surgical removal of the fibrous tumor was done. At present, after 5 years of the last operation, the patient is getting well, with no recidive.
