Great Auricular Nerve

The great auricular nerve is a nerve arises from cervical plexus, which is made up of fibers from the second and third cervical nerves (C2, C3). It provides sensory innervation to the skin of the external ear, the adjacent portion of the scalp, cheek, and angle of the jaw. The great auricular nerve also communicates with the lesser occipital nerve, the auricular branch of the vagus nerve, and the posterior auricular branch of the facial nerve.
