Abstract
The dorsal nasal artery is not a constant artery The artery traveled in the subcutaneous tissue layer of the nasal dorsum on the transverse nasalis muscle and its midline nasal aponeurosis which connected the muscles on both sides Bilateral dorsal nasal arteries existed only in 34 In 28 of the specimens a single and large dorsal nasal artery was presented The diameter was 04 ± 02 mm when bilateral dorsal nasal arteries were present and 07 ± 03 mm in a single artery The largest artery was 12 mm The artery usually crossed the midline at the middle third part of the nose over the upper lateral cartilages to form an anastomosis with the contralateral lateral nasal artery as the oblique nasal artery in 14 The artery might descend and communicate with the ipsilateral lateral nasal artery in 6 or descended as a midline artery and form the nasal tip plexus in 8 In 38 of the specimens the arteries became small formed a subcutaneous plexus and randomly distributed on the superficial layer of the subcutaneous tissue in the upper twothirds of the noseDuring the injections at the upper bony and middle cartilaginous part of the nose for nasal dorsal augmentation the injector has to make sure the cannula tip is in the preperiosteal plane by reinsertion of the cannula if needed due to the chance of encountering the large single dorsal nasal artery at the midline
