The nasal tip blood supply was studied through anatomic dissections and microangiography in 31 fresh cadaver specimens. The lateral nasal artery was present in all specimens, bilaterally in 30 (97 percent) and unilaterally in one (3 percent) and was located in the subdermal plexus 2 to 3 mm superior to the alar groove. The columellar branch of the superior labial artery was visualized bilaterally in 3 specimens (9 percent) and unilaterally in 21 (68 percent), and was absent in 7 (23 percent… CONTINUE READING
