These include cutaneous branches of the cervical plexus supplying the skin overlying the posterior triangle; the platysma and omohyoid muscles; the spinal accessory nerve, which innervates the SCM and trapezius muscles; the deep cervical lymph nodes; the brachial plexus; and numerous arteries and veins--prominent is the external jugular vein (see Figure 2).
Yadav et al (3) reported a case where the external jugular vein crossed superficially to the sternocleidomastoid muscle and ended in the internal jugular vein, above the level of the superior belly of omohyoid muscle (incidence, 1 of 10 cadavers).
The sternohyoid and omohyoid muscles can also be dissected; the length of the dissection depends on the distance from the hyoid bone to the area to be reconstructed.
