Abstract
Despite the fact that the blueprint of the whole body is unravelled, faultlessly during the growth and
development of an animal; but amazingly variations do occur. During routine dissection of head and neck
in a middle aged cadaver in the Post Graduate Department of Anatomy of this medical college, we found
variation in the formation of external jugular vein on both sides, which was formed by the continuation of
undivided trunk of retromandibular vein. The facial vein and posterior auricular vein were the tributaries of
external jugular vein. The sound anatomical knowledge of variations of the veins of head and neck is
essential to the success of surgical procedures. The embryological evaluation of the above anomaly was
done and compared with the available literature which showed that the observed variation was rare.
