The lingual artery constitutes one of the branches of the external carotid artery, which is responsible for the vascularization of the tongue and neighbour regions. The hemorrhage caused by a lesion of the lingual artery can occur during a dental procedure (surgical accidents by the use of an instrument or rotating disc), by trauma, biopsy and dental implant. In some cases is difficult to stop the hemorrhage of injured vase, so is necessary to realize the extraoral ligature of this artery. Hence, this work studied the anatomic aspects of the lingual artery, by forty-eight dissections of twenty-four corpses settled in formol 10%, aiming to detail the origin, pathway and anatomic relations of the lingual artery in the region of anterior trigone of the neck, and also to measure the distances among the lingual artery and the arteries: facial, superior thyroid and with the bifurcation of the common carotid. The results concluded that the lingual artery is found in a position more inferior than classicaly described, based on the digastric muscle and the hypoglossal nerve; and that the hyoid bone can be used as a point of reference for the surgical access to the lingual artery in the region of the anterior trigone of the neck
