The vascularization of the auricle is poorly documented, despite the developments in auriculotherapy and reconstructive surgery. The aim of this study was to describe its arterial distribution using two techniques: diaphanization and anatomical dissection. The study was conducted after intravascular injection of eight diaphanized auricles and ten that were dissected. Dissection showed that the auricle is vascularized by an anterior flow arising in the superficial temporal artery and also by a posterior flow arising in the posterior auricular artery in eight cases out of ten, and in the occipital artery in the remaining two. Diaphanization revealed the three-dimensional arterial distribution of preserved specimens. This technique has a didactic use to complement to standard anatomical dissection.
