A Case Report: An Unusual Variation in the Facial Artery

Abstract

The facial artery is the main artery supplying the face occasionally. It gives three branches on the face, the inferior labial, the superior labial, and the lateral nasal, and terminates as the angular artery. Due to congenital vascular variations in the facial artery, it has been considered in the dissection of the head and neck region. During the dissection of a 65-year-old woman to expose this region, we discovered that the left facial artery is terminated by the superior labial artery after giving off the submental and inferior labial branches. At the level of the left oral commissure, the facial artery was attached to the buccinator muscle as connective tissue, with a noticeable decrease in diameter. The purpose of this study is to report a new variation of the facial artery that is particularly important for cadaver dissection, and head and neck surgeries, as well as for facial artery angiography.
