The dorsal nasal artery (a. nasodorsalis) is a large artery that supplies the bone elements and skin of the external nose. The nasal dorsal arteries can be divided into several categories depending on their location and function. One of the most important areas of a. nasodensalis is a pyramid. This is the area located just to the back of the nose near the choana (the opening for the breath to exit). The nasal dorsal petrous blood supply provides nutrition to the bone covering the choanae and the tissues in this area, including cartilage and skin. This area is especially important for the function of the respiratory system and the ability to breathe through the nose. In addition, the nasal dorsal inferior nasal artery supplies the inferior nostril and is associated with the function of smell.
Nasolateral dorsal arterial anastomoses are networks of blood vessels that form connections between the large arteries of the nasal cavity and the external nasal junction. These anastomotic connections can facilitate the rapid and efficient delivery of oxygen and nutrients to the mucous membranes of the nose and face. The arteries of the facial region are involved in numerous clinical conditions,
