Summary

Human anatomy is an ocean of unending variations and its mysteries are being unravelled since ages. Knowledge of variations in the superficial veins of head and neck is essential to carry out successful surgical procedures. During routine dissection of head and neck of two middle aged male cadavers, in the Department of Anatomy, Calcutta National Medical College, Kolkata, India, we came out with some interesting venous architecture. The retromandibular vein on the left side of both the cadavers was found to be undivided and joined with the facial vein in the neck at an acute angle to form a common venous trunk at variable distances from the angle of the mandible. That trunk ultimately drained into the left subclavian vein. This might be the result of disappearance of the cephalic part of the external jugular vein and formation of an additional communication between common facial vein and the external jugular vein in foetal life. In one case, we also came across an extra transverse communication between that common trunk and the internal jugular vein. A detail of those cases with embryological explanation is attempted.

KEY WORDS: External jugular vein; Retromandibular vein; Facial vein; Variation, communication.
