The nomenclatures of the lateral nasal artery and the dorsal nasal artery were researched.

However, caution is advised if the alar base has been previously excised, if the alar base incisions extend more than 2 mm above the alar groove, and the lateral nasal artery is damaged bilaterally.

Results:Besides the branches of anterior ethmoidal artery and dorsal nasal branches of ophthalmic artery, the primary blood supply to the nose was derived from the lateral nasal arteries.
