There are five main branches to the auriculotemporal nerve; the anterior auricular, articular, parotid, superficial temporal and branches to the external auditory meatus: The anterior auricular branch provides somatosensory innervation to the skin of the ear, including the tragus and part of the helix. The nerve arises just behind the middle portion of the sternocleidomastoid muscle and shortly thereafter curves around its posterior border and emerges on the muscle's anterior surface. The great auricular supplies the whole of the cranial (medial /back) surface of auricle and the posterior part of lateral (front) surface (helix, anthelix, and lobule).
