The auriculotemporal nerve is a tributary of the mandibular division of cranial nerve five, the trigeminal nerve. It contains sensory, vasomotor, and parasympathetic fibers. It has a superior and inferior root that originates from the trigeminal nerve, encircles the middle meningeal artery ultimately traveling inferior to the temporomandibular joint and up the temple providing sensation to parts of the ear, temporomandibular joint, scalp, as well as secretory and vasomotor innervation to the parotid gland. This nerve is clinically relevant in the setting of temporal mandibular joint disease repair, postoperative complications in a parotidectomy, and trigeminal neuralgia.
