Twenty-five facial arteries were examined radiographically in 19 fresh cadavers that had been injected systemically with a lead oxide-gelatin mixture. Major branches of the facial artery in the upper lip and nose were investigated, and the anatomical variations were classified into three types on the basis of the anatomy of the lateral nasal artery which was determined as an artery, running toward the alar base. In 22 cases (88 percent), the facial artery bifurcated into the lateral nasal artery and superior labial artery at the angle of the mouth. In two cases (8 percent), the facial artery became an angular artery after branching off into the superior labial artery and the lateral nasal artery sequentially. In one case (4 percent), the facial artery became an angular artery after branching off into the superior labial artery, and the lateral nasal artery then branched off from the superior labial artery. Branches from the lateral nasal and superior labial arteries were observed stereographically. Vascular anastomoses between those branches were created in the upper lip, columella base, and nasal tip, and an intimate vascular network was formed. With a vascular network in the mucosa of the upper lip, a bilobed upper-lip flap was created for a clinical case with a full-thickness defect of the ala.
