Termination of the facial vein into the external jugular vein: An anatomical variation

Abstract

Different patterns of variations in the venous drainage have been observed in the past. During routine dissection in our Department of Anatomy, an unusual drainage pattern of the veins of the left side of the face of a middle aged cadaver was observed. The facial vein presented a normal course from its origin up to the base of mandible, and then it crossed the base of mandible posteriorly to the facial artery. Thereafter, it joined with the anterior division of retromandibular vein to form the common facial vein, which drained into the external jugular vein directly. Sound anatomic knowledge of the above variation in facial veins is essential to the success of surgical procedures in this region.
