The Posterior Auricular Vein is a vein that drains the scalp posterior to the auricle and the back of the auricle itself. It is a part of the human circulatory system and plays a crucial role in the venous drainage of the head and neck.

Structure

The Posterior Auricular Vein arises from the pinna of the ear and the scalp posterior to the auricle. It descends behind the auricle, where it joins the posterior division of the superficial temporal vein to form the external jugular vein.

Function

The primary function of the Posterior Auricular Vein is to drain blood from the region behind the ear and the outer part of the ear. It then carries this deoxygenated blood towards the heart, contributing to the overall circulation of blood in the body.

Clinical significance

Knowledge of the Posterior Auricular Vein is important in several medical procedures, including cannulation, venipuncture, and in surgeries involving the ear or surrounding areas.
