The facial artery is the major artery for the facial skin. Along with it are secondary sources: the terminal branches of the superficial temporal artery and the transverse facial artery. In their trajectory, the arteries follow several anatomical territories: bones, muscles and intermuscular septa, fascia and sometimes tendons and nerve fibers. Toward the surface, reaching a microscopic level, the vessels will follow the connective tissue to reflect regional three-dimensional disposition. The arteries branch out on the surface of the deep fascia, and afterwards their branches climb the connective network of superficial fascia, among the adipose lobules, towards the subdermal plexus. Vascular anastomoses take the form of irregular polygons. These subdermal anastomoses allow restoration of blood flow, even when there has been an extensive dissection of the skin. Depending on the form of the cutaneous vascular area of an artery, three forms of subdermal plexuses were described: radiate, parallel and circular. Every source artery which supplies a block made up of muscles, nerves and bones is usually responsible for also nourishing the skin area situated right above it. This type of composite tissue segment, with a common dependency towards a source artery, was named angiosome. A thorough knowledge of the microvascularisation of the facial region is useful for planning surgical interventions with aesthetic and reconstructive purposes, cosmetic surgery interventions and also facial transplants, as the main objective in such an intervention is the revascularisation of the transplanted tissue.
