The retromandibular vein is formed by the union of the superficial temporal and maxillary veins. It enters the parotid gland, superficial to the external carotid artery but beneath the facial nerve, and between the mandibular ramus and the sternocleidomastoid. It then divides into an anterior branch and a posterior branch. The anterior passes forward and joins the facial vein, forming the common facial vein. The posterior joins the posterior auricular vein, becoming the external jugular vein.
