A rare termination of left common facial vein into left subclavian vein. A case report

During routine dissection of head and neck, an unusual drainage in pattern of the veins on the left side of the face was observed in an adult male cadaver. In the present case, he superficial temporal vein united with maxillary vein to form retromandibular vein within the substance of the left parotid gland. The anterior division of retromandibular vein joined with facial vein to form common facial vein that drained into left subclavian vein directly. Knowledge of such variations is important for surgeons performing head and neck surgeries. Facial veins are often grafted into carotid endarterectomy.
