Abstract
The purpose of this study was to obtain anatomic data on the branching levels of the deep branches of the supraorbital artery (SoA) and of the supratrochlear artery (StA) in pericranial flaps. Ten preserved cadavers were used for this study. Each vessel was identified on 12 sides. The deep branch of the SoA had a larger caliber than that of the StA in seven of nine sides. The branching level of the deep branch of the SoA was cephalad to that of the StA on six of nine sides. The deep branch of the SoA diverged shortly after emerging from the supraorbital foramen or notch. However, there were a few cases in which the branch originated at a distance of a few millimeters before or after the foramen or notch. From a practical standpoint, dissection of this pericranial flap below the level of the supraorbital ridge is not advised, and preservation of both feeding arteries is encouraged in order to establish abundant vascularity for this flap.
