A Completely Unique Branching Pattern of the Facial Artery.

This case report describes a recent case where a patient with hypopharyngeal cancer underwent resection and reconstruction with a free jejunum flap and the surgeons found a rare variation in the branching pattern of the common carotid artery. Specifically, the left facial artery arose directly from the common carotid artery, whereas the left superior thyroid artery arose from the facial artery. This branching pattern has not been reported previously. Although this is a hitherto unique case, head and neck and reconstructive surgeons should be aware of the possibility that this branching pattern may be present because it could complicate the outcomes of both neck dissection and reconstruction by free tissue transfer.
