The Auriculotemporal Nerve Viewed Laterally in a Human Male

Description

Emerging from the mandibular division of the trigeminal nerve (V3) in the infratemporal fossa, the auriculotemporal nerve (nervus auriculotemporalis) is traced as it courses posterior to the neck of the mandible and climbs superiorly alongside the temporomandibular joint. The lateral profile places the mandibular condyle and temporal bone in clear relationship, with the nerve passing deep to the parotid region before supplying the auricle and temporal scalp. Proximally, the nerve’s roots encircle the middle meningeal artery and communicate with the otic ganglion, carrying postganglionic parasympathetic secretomotor fibers toward the parotid gland. Close cervical nerve contours are included for orientation. Clinically, this is the nerve that ties TMJ pain to ear and temple symptoms, and its superficial temporal course makes it a frequent culprit in temporal headaches and post-traumatic neuralgia. It also frames a classic teaching point in Frey syndrome: after parotidectomy, aberrant regeneration through auriculotemporal pathways can produce gustatory sweating and flushing over the preauricular skin. Surgery lives here. Knowing how the nerve hugs the mandibular neck and skirts the joint capsule helps avoid iatrogenic injury during preauricular TMJ approaches, condylar fracture fixation, and parotid dissection. Use this lateral head and neck rendering to anchor lectures in dental anatomy, oral and maxillofacial surgery, or neuroanatomy when introducing V3 branches and the otic ganglion. It also fits operative atlases and patient-facing counseling materials that need a clean explanation of referred otalgia, TMJ-associated neuropathic pain, or postoperative Frey syndrome patterns.
