Origin

The auricular branch of the occipital artery is an inconstant branch arising from the occipital artery (Dorland, 2011). As the occipital artery ascends tortuously in dense superficial fascia of the scalp, between the skin and occipital belly of occipitofrontalis muscle, it gives off the auricular branch of the occipital artery.

Course

The auricular branch of the occipital artery courses laterally within the superficial fascia of the scalp towards the posterior aspect of the ear.

Branches

There are no named branches, however, the auricular branch of the occipital artery anastomosis with the posterior auricular artery behind the ear.

Supplied Structures

The auricular branch of the occipital artery provides arterial supply to the auricle (pinna) of the ear (Dorland, 2011).

Artery

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
