Abstract

Superficial head and neck vessels are increasingly used in surgical procedures and are especially important in facial transplantation surgeries. We report a variant course of the submental vein observed during a dissection of a 79-year-old-male embalmed cadaver: a left submental vein running caudally across the intermediate tendon of the digastric muscle, separating from the course of the submental artery and emptying directly into the common facial vein in the carotid triangle. Such course may complicate submental island flap harvesting, as well as the graft manipulations and reattachment, since the vein could be damaged during the conventional procedure. This report therefore extends current knowledge of the variations of the vascular anatomy of the head and neck.
