Abstract

Background: Injections of filler into the nose for dorsum augmentation have a higher risk of complications due to the complicated blood supply and anastomotic channels in this area. Objectives: The aim of this study was to determine the anatomical features and location of the dorsal nasal artery (DNA), and to provide clinical anatomical information to reduce side effects and severe complications in the perinasal area. Methods: Using the 31 cadaveric noses in Asians, dissections and histologic examinations were performed to identify the location and depth of the vascular structures including DNA. Results: Dorsal nasal artery ran downward at 20.3 ± 3.5 mm from the intercanthal line and the communicating branch that connected the bilateral DNAs was located 8.5 ± 3.5 mm inferior to the intercanthal line. The DNA was located at 4.4 ± 3.2 mm, 4.6 ± 4.4 mm, and 5.2 ± 4.4 mm lateral to the midline of the nose on the intercanthal, quadrisected, and bisected lines, respectively. At the level of nasal bone, DNA was located superficial to the muscular layer and it runs inferolaterally on dorsum on nose. It was running more deeply and located beneath the fibromuscular layer at the cartilaginous portion of the dorsum of nose. Conclusions: Injection into deep fatty layer may reduce the risk of arterial injury and the consequent complications. However, in a hooked nose, the tip of the needle traveling along the deep layer approaches the superficial layer due to the convexity of the hump as it passes over it, which can increase the probability of damaging the DNA.
