Cervical Plexus

"Cervical plexus is formed by the ventral rami of upper four cervical spinal nerves and supply some of the areas of skin on the head, neck and chest through its cutaneous branches. It lies deep to the prevertebral fascia, and its superficial cutaneous branches, the lesser occipital nerve, great auricular nerve (GAN), transverse cervical cutaneous nerve (TCCN) and supraclavicular nerves pierce the fascia to supply the skin. Transverse cutaneous nerve arises from the second and third cervical ventral rami and then curves around the midpoint of posterior border of sternocleidomastoid muscle and runs obliquely forwards passing deep to the external jugular vein. It crosses the anterior border of the muscle and perforates the deep cervical fascia before dividing into ascending and descending branches. The ascending branch supplies the skin of upper anterior areas of neck after piercing the platysma while the descending branch supplies anterolaterally to the skin of neck till the level of sternum. Anastomoses between the TCCN and the cervical branch [CB] of facial nerve are regularly present. The anatomic locations of these anastomoses are poorly documented in the medical literature. Herein, we report the anatomic location of anastomoses between the TCCN and CB of facial nerve and discuss its clinical significance.
