The zygomaticofacial nerve is a terminal branch of the zygomatic nerve, which is a division of the maxillary nerve. From the zygomaticofacial foramen, where the nerve perfortes the orbicularis oculi muscle as well as stimulates the skin on the protrusion of the cheek, the zygomaticofacial nerve arises on the face.
The area of skin over the prominence of the cheek is supplied by this nerve.
The zygomaticofacial nerve exits the foramen by the similar name in order to supply the skin of the malar eminence along with lateral cheek and travels alongside the inferolateral orbit. Below the lateral canthus, the foramen can be palpated above the inferolateral rim and also be blocked through direct infiltration.
