The auriculotemporal nerve passes medially to the neck of the mandible and then turns superiorly, posterior to its head and anterior to the auricle. It then crosses over the root of the zygomatic process of the temporal bone, deep to the superficial temporal artery.

It supplies the auricle, external acoustic meatus, tympanic membrane, and the skin in the temporal region.

It also carries postganglionic parasympathetic fibers from the otic ganglion to the parotid gland.
