title: [Anatomical observation on the external nasal arteries].
abstract: An anatomical study of the arteries of the external nose was undertaken in 16 adult cadavers. These arteries included dorsal nasal artery, the lateral nasal artery, the naso-alar artery, the lower naso-alar marginal artery and the nasoseptal artery, etc. Eighty-five percent of them was branches of the facial artery. The results showed that the external nasal arteries distributed around the nostril in a small and a large circle, which suggested that there may be a two-way blood supply on the nasal tip and the columella. The circulation of the internal and external carotid artery may join on the nasal tip where the blood supplies still remain even after bilateral carotid arteries are ligated. The names of the branches and their features are discussed in the paper.
