The transverse cervical artery crosses the posterior triangle to supply the trapezius (superficial branch) and the dorsal scapular muscles (deep branch). The deep branch — the dorsal scapular artery — runs parallel to the dorsal scapular nerve to supply the rhomboids and levator scapulae. The trapezius myocutaneous flap is based on the superficial branch of the transverse cervical artery.

The trapezius musculocutaneous flap based on the transverse cervical artery superficial branch provides reliable pedicled tissue for posterior neck and occiput coverage after oncological resection. The flap is raised along the inferior trapezius with a skin paddle over the lower trapezius and rhomboid region.
