Supplementary Material for: Influence of the Topographic Vascular Distribution of the Face on Dermal Filler Accidents

Objective: Dermal fillers are an important tool in the field of aesthetic dermatology. Fillers are relatively noninvasive and easy to use but are not free of secondary complications. The main complications are vascular and are due to either the compression of an artery or the direct introduction of the product into the arterial lumen. The aim of this study is to provide an overview of the vascular territories of the face to avoid many possible complications when using facial fillings. Anatomical localization of the main arterial supply to the face has been described to assess the risk of vascular injury. Methods: The authors dissected 17 hemifaces of embalmed adult cadavers that had previously been injected, through the common carotid artery, with latex containing a red dye. Results: A topographic distribution was generated by facial regions following a clinical approach from where the facial fillings were placed and related to the pathways of the arteries. Following these criteria, we established 8 topographic regions (I–VIII) that indicate the main vascular problems of each of these regions. Detailed anatomical localizations of the main arteries in these topographic regions of the face and their relationships are described. Conclusions: The highest index of vascular lesions and especially visual alterations occurred for fillings of the upper third of the face. To prevent and avoid this type of lesion, it is advisable to avoid, as much as possible, treatments with filling materials in the upper third of the face, mainly including the glabellar and nasal region (III) and supraorbital region (VIII).
