Zygomaticofacial nerve
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.[1] The zygomaticofacial nerve penetrates the inferolateral angle of the orbit, emerging into the face through[2]: 631 the zygomaticofacial foramen,[2]: 615 then penetrates the orbicularis oculi muscle to reach[2]: 631 and innervate the skin of the prominence of the cheek.[2]: 631 [3]

Anatomy
Communications
The zygomaticofacial nerve forms a nerve plexus with the zygomatic branches of facial nerve (CN VII), and the inferior palpebral branches of maxillary nerve (V2).[2]: 631
Variation
The nerve may sometimes be absent.[2]: 631
