Variation in the formation of the retromandibular and the external jugular veins with embryological overview: A case report
Awareness of the formation and termination of the head & neck's superficial vein, such as jugular veins, are imperative for anatomists, surgeons, and radiologists during interventional procedures. We report an uncommon variation in the formation of the retromandibular vein and external jugular vein (EJV) in an embalmed male cadaver's right side. The joining of the facial vein and superficial temporal vein within the parotid gland formed the retromandibular vein (RMV). The anterior division joined with the submental vein forming an anomalous venous trunk. The anomalous vein united with the EJV forming a common trunk in the lower third of the neck and terminated into the subclavian vein. We compared the available literature and justified the embryological development of this rare variation.
