Facial subdermal vascular network flap: anatomic study and clinical application

Despite the numerous flaps for facial reconstruction that have been described, the search for the ideal flap with good color matching and minimal donor-site morbidity continues. In the past 3 years we have repaired 13 facial defects with success using the lateral genicervical flap - a type of facial subdermal vascular network flap (SVNF) - with a pedicle located on the preauricular region. An anatomic study of the facial SVNF, including blood supply and vascular distribution of the face and anatomic characteristics of facial vessels, based on 14 cadaver dissections, was carried out. The blood supply of the facial skin basically originated from the branches of the facial, superficial temporal and infraorbital arteries. The lateral genicervical skin was supplied basically by the branches of the facial, superficial temporal and occipital arteries, but also by the terminal branches of the superior thyroid artery. The branches diverging from these arteries became superficial and formed a subcutaneous arterial network. The arterioles from the network went to the corium layer and formed a subdermal arterial network whose arterioles anastomosed with each other in a honeycomb-like structure. The vascular distribution presented certain directivity on different areas. The blood supply of the pedicle originated from the subdermal vascular network formed by the perforator branches of these arteries. The arterioles from the facial and superficial temporal arteries anastomosed in the lateral genicervical region. From the anatomic study, we think that the viability of the facial SVNF depends basically on the subdermal vascular network formed by the perforator branches of the pedicle, and that the anastomoses between the facial and superficial temporal arteries provide a solid anatomic basis to the lateral genicervical flap. The clinical data also indicated that this flap is a useful alternative for facial, especially superficial temporal, defects. But the directivity must be taken into account in its clinical application.     

Arterial anatomy of the lateral orbital and cheek region and arterial supply to the “peri-zygomatic perforator arteries” flap

Arterial anatomy of the lateral orbital and cheek region and subsequently of the “peri-zygomatic perforator arteries” flap is described, based upon the dissection of the 24 human cadaver head halves. Each specimen was dissected in subdermal, first fascial and deep level. The subdermal vascular network of lateral orbital and cheek region, its orientation and contributing arteries were studied. Origin, perforation sites and diameters of transverse facial, zygomaticoorbital, zygomaticofacial and zygomaticotemporal arteries were also described and measured. Our findings support the view that the cheek island flap used for lower eyelid is a reverse flow axial pattern flap. It includes arterioles of the transverse facial artery, which are part of the subdermal vascular plexus and are uniformly longitudinally oriented. The flap receives its blood supply via perforators of the zygomaticoorbital, zygomaticofacial and zygomaticotemporal arteries, which are connected via their terminal branches with transverse facial artery.

The superficial temporal artery: anatomical type and clinical application to the flap of the fascia temporal superficialis

The goal of our study is to assess the anatomical type of the superficial temporal artery (STA) in the black population using the classification of Ricbourg et al.. Forty-seven fresh cadavers and three extracted and frozen heads were included in this study. The external carotid artery was isolated in the neck and injected by Rhodopas stained with Congo Red. The superficial temporal artery was dissected using a Y-shaped skin incision. The last step of the procedure was to remove the flap of the fascia superficialis temporis. The third segment of the superficial temporal artery and its terminal branches were studied. This segment courses cephalad and wraps the zygomatic arcade. It splits into two terminal branches: the temporo-frontal and the temporo-parietal ones. The most important of its collaterals, the zygomato-maleus artery, plays a crucial role for distinguishing the subtypes of STA according to the classification of Ricbourg et al.. Indeed, this branch can be subdivided into two types: --type I: the zygomato-malar artery arises from the trunk of the STA; it courses perpendicular and with a slightly ascending direction; this type accounts for 93% of the cases. --type II: the zygomato-malar artery originates from the branch of the temporo-frontal artery. Its course is either horizontal or caudad. This type accounts for 3% of the cases. Our results confirm those of Ricbourg et al.. Thus, we could not CONFIRM the notion of a racial predominance of typology of the STA in our context. We did not study the dimensions of STA and also the level of its bifurcation. Indeed, it has been largely reported in the literature. These elements constitute the anatomic basis of the surgical use of temporal flaps. The vessel-containing tissue in which travels the STA forms the so-called fascia temporalis superficialis whose plasticity and polyvalency are critical during the procedures of plastic and reconstructive surgeries.
