Abstract

Blood supply of the skin of the face is mainly provided by 3 branches of the external carotid artery: facial artery (FA), superficial temporal artery (STA) and transverse facial artery (TFA) which is a branch of the STA. The aim of the study was to describe the arterial territories of the skin of the face depending on the external carotid branches. After dissection of the first two centimeters of these arteries on one side, we performed an injection of India ink of different colors in the arteries in order to describe the arterial territories (angiosomes) of the face on 24 embalmed cadavers. The lips and the tip of the nose were vascularized in most cases by the FA. The STA vascularizes the temporal and frontal areas and a part of the auricle. The buccal area blood supply is coming from the FA with a participation of the TFA which is variable (10/24 cases), and the zygomatic area blood supply is coming from the STA with a participation of the TFA (9/24 cases). Variations in the angiosomes of the face have to be considered in reconstructive surgery, and in face transplantation.
