Great refers to the distinction between it and the Auriculotemporal nerve, which is the less influential of the two.

Then they form the somatosensory (superior) root of the auriculotemporal nerve.

The superficial temporal vessels and the auriculotemporal nerve cross it from below upward.

The rest is provided by the auriculotemporal nerve, which supplies the skin anterior to the external auditory meatus.

The auriculotemporal nerve has also recently been implicated in development or perpetuation of migraine headaches .

The auriculotemporal nerve arises as two roots from the posterior division of the mandibular nerve.

Pain from parotitis, a condition which can be caused by mumps, will be carried by the auriculotemporal nerve to the brain.

There, they synapse with postganglionic fibers which reach the gland by hitch-hiking via the auriculotemporal nerve, a branch of the mandibular nerve.

This nerve synapses in the otic ganglion and its postganglionic fibers form the inferior, parasympathetic root of the auriculotemporal nerve.

After a parotidectomy, the nerves from the Auriculotemporal Nerve that previously innervated the parotid gland can reattach to the sweat glands in the same region.

The postganglionic parasympathetic fibers are then distributed via the auriculotemporal nerve (branch of the trigeminal nerve) to the parotid gland.

Signs and symptoms include erythema (redness/flushing) and sweating in the cutaneous distribution of the auriculotemporal nerve, usually in response to gustatory stimuli.

Postganglionic parasympathetic fibers travel with the sympathetic fibers of the auriculotemporal nerve (a branch of CN V3) to supply the parotid gland.

Lateral pterygoid and the auriculotemporal nerve are lateral relations, the chorda tympani nerve lies medial near its upper end and medial pterygoid is an inferomedial relation.

The fibres synapse in the otic ganglion, and post-ganglionic fibres then travel briefly with the auriculotemporal nerve (a branch of V3) before entering the body of the parotid gland.

The auriculotemporal nerve is a branch of the mandibular nerve that runs with the superficial temporal artery and vein, and provides sensory innervation to various regions on the side of the head.

The middle meningeal artery is intimately associated with the auriculotemporal nerve which wraps around the artery making the two easily identifiable in the dissection of human cadavers and also easily damaged in surgery.

The auriculotemporal nerve passes medially to the neck of the mandible, gives off parotid branches and then turns superiorly, posterior to its head and moving anteriorly, gives off anterior branches to the auricle.

The two roots re-unite and shortly after the branching of secretomotor fibers to the parotid gland (parotid branches) the auriculotemporal nerve comprises exclusively somatosensory fibers, which ascend to the superficial temporal region.

The innervation of scalp can be remembered using the mnemonic, "Z-GLASS" for, Zygomaticotemporal nerve, Greater occipital nerve, Lesser occipital nerve, Auriculotemporal nerve, Supratrochlear nerve and Supraorbital nerve.

The common stem of the infraorbital and mandibular branches passes between the two roots of the auriculotemporal nerve and becomes the middle meningeal artery; the original supraorbital branch of the stapedial is represented by the orbital twigs of the middle meningeal.

Exiting the plexus within the lesser petrosal nerve, these preganglionic fibers synapse with cells in the otic ganglion, which send postganglionic fibers into the mandibular division of the trigeminal nerve, then into the auriculotemporal nerve, finally reaching their target, the parotid gland.

The first or mandibular portion passes horizontally forward, between the neck of the mandible and the sphenomandibular ligament, where it lies parallel to and a little below the auriculotemporal nerve; it crosses the inferior alveolar nerve, and runs along the lower border of the lateral pterygoid muscle.

Frey's publication about auriculotemporal nerve syndrome, now widely known as "Frey's syndrome" ("zespół Łucji Frey" in Polish), was published in 1923, first in Polish journal "Polska Gazeta Lekarska", and later that year in renowned French journal "Revue Neurologique".

As it crosses the zygomatic process, it is covered by the Auricularis anterior muscle, and by a dense fascia; it is crossed by the temporal and zygomatic branches of the facial nerve and one or two veins, and is accompanied by the auriculotemporal nerve, which lies immediately behind it.
