The zygomaticofacial nerve (or zygomaticofacial branch of zygomatic nerve or malar branch of zygomatic nerve) is a cutaneous (sensory) branch of the maxillary nerve (CN V2) that arises within the orbit. The zygomaticofacial nerve penetrates the inferolateral angle of the orbit, emerging into the face through the zygomaticofacial foramen, then penetrates the orbicularis oculi muscle to reach and innervate the skin of the prominence of the cheek.
