The auriculotemporal nerve is a branch of the mandibular nerve (V3) that runs with the superficial temporal artery and vein, and provides sensory innervation to various regions on the side of the head.
Anatomy
The auriculotemporal nerve arises as a posterior division of the mandibular branch of the trigeminal nerve. It has somatosensory and parasympathetic roots. The somatosensory fibres supplies the auricle, external acoustic meatus, outer side of the tympanic membrane, the skin in the temporal region (superficial temporal branches), and a few fibres to the temporomandibular joint. Its proximal trunk is located superficially just anterior to the tragus. The parasympathetic root innervate the parotic gland.
The external ear innervated by four sensory nerves: greater auricular nerve, lesser occipital nerve, auricular branch of vagus nerve, and the auriculotemporal nerve.

Technique
Landmark Guided
- Position: patient seated and physician standing beside them, or with the patient supine and their head in a neutral position.
- Injection point is just anterior to the tragus
- Use a 5 mL syringe with a 30-gauge needle
- Insert the needle 1–2 mL into the subcutaneous tissue to a depth of about 4–6 mm.
- Aspirate to exclude arterial puncture and inject
