If changing this then please provide a reference. None of the 4 anatomy text books that I looked through mentioned the buccal artery descending down the neck and all described it as per current main article:

This was previously in the main article but I removed it as it is very clearly no about the buccal artery and makes no sense anatomically:


The buccal artery then pierces the platysma muscle and, on the medial margin of the sternocleidomastoid muscle runs into the deep neck between the middle and posterior scalene muscles. Generally paralleling the course of the recurrent laryngeal nerve and the vagus nerve below the aortic arch, it continues inferiorly along the thoracic aorta. At the level of the eighth thoracic vertebra, each descending buccal artery (right and left) terminates in a branch that bifurcates to supply the 7th and 8th intercostal spaces. All other intercostal spaces (except for the 1st and 2nd) 3-6 and 9-11 including subcostal space, are supplied by direct branches from the thoracic aorta.

Clinical Significance[edit]

The buccal artery - specifically the right buccal artery - is of clinical significance as it courses with the thoracic aorta. Because the buccal arteries are bilateral with respect to the aorta, which is offset from the spine to the left, and not the vertebral column itself, the right buccal artery runs between the right side of the aorta and the left side of the vertebral column. This represents a potential point of constriction that is used as a reliable indicator of aortic aneurysm: Compression of the right descending buccal artery (due to adjacent aortic aneurysm) results in diminished blood supply to the right 7th and 8th intercostal spaces, causing only these segments to develop a distinguished pale appearance in comparison to the rest of the rib cage.
