Nerve: Zygomaticotemporal nerve

Distribution of the maxillary and mandibular nerves and the submaxillary ganglion
Latin	Ramus zygomaticotemporalis nervi zygomatici
Gray's	p.889
From	Maxillary nerve

The zygomaticotemporal nerve or zygomaticotemporal branch (temporal branch) is a small nerve in the face. It is derived from the maxillary nerve, a branch of the trigeminal nerve. It runs along the lateral wall of the orbit in a groove in the zygomatic bone, receives a branch of communication from the lacrimal nerve, and passes through the zygomaticotemporal foramen in the zygomatic bone to enter the temporal fossa.

It ascends between the bone and the substance of the temporalis muscle, pierces the temporal fascia about 2.5 cm. above the zygomatic arch, and is distributed to the skin of the side of the forehead, and communicates with the facial nerve and with the auriculotemporal branch of the mandibular nerve.

As it pierces the temporal fascia, it gives off a slender twig, which runs between the two layers of the fascia to the lateral angle of the orbit.
