    Study Notes

    Arterial Supply to Head & Neck

    • The main arterial blood supply to the head and neck originates from the aortic arch which gives rise to the brachiocephalic, left common carotid and right subclavian arteries.
    • The brachiocephalic splits into the right subclavian and the right common carotid arteries.
    • The right subclavian gives rise to the right vertebral artery.
    • The right common carotid forms the internal and external carotid arteries.
    • The arch of the aorta gives rise to the left subclavian and the left common carotid arteries directly.
    • The left subclavian gives rise to the left vertebral artery.
    • The external carotid artery branches into 8 main arteries: superior thyroid, ascending pharyngeal, lingual, facial, occipital, posterior auricular, superficial temporal and maxillary arteries.
    • The external carotid artery supplies blood to the muscles and skin of the face as well as the submandibular gland.
    • Occipital Artery: supplies muscles in the posterior neck, skin of the neck and ear, and the scalp in the occipital region.
    • Posterior Auricular Artery: supplies muscles in the posterior neck, skin over and around the ear, and the ear structures.
    • Superficial Temporal Artery: supplies some of the skin and muscles of the scalp, parotid gland, and temporomandibular joint.
    • Maxillary Artery: a very complex vessel that supplies blood to the whole maxillofacial region including the hard and soft tissues of the maxilla, mandible, nasal cavity, and deep facial areas. The artery also supplies the teeth.
    • Superior Alveolar Artery: a branch of the maxillary artery that supplies the maxillary teeth. It splits into posterior, middle, and anterior branches.
    • Inferior Alveolar Artery: another branch of the maxillary artery that supplies the mandibular teeth. It forms a dental branch, an incisive branch, and the mental artery.

    Summary

    • Arterial supply to the head and neck is complex.
    • It is important to be aware of two main bilateral vessels: internal and external carotid arteries.
    • The external carotid artery provides blood supply to most of the mouth and face.
    • Key branches are: lingual, facial, and maxillary arteries, which are important for dentists to know.
    • It is important to have an awareness of other branches.
    • Use a pneumonic to help remember the arteries and their branches.

    Caveat

    • Anatomical variations exist, so the arrangement and branching of the vessels may differ between individuals.
    • There may be some debate on the most common presentation of vessels in different sources.
