The zygomaticofacial nerve is blocked by injecting the inferior lateral portion of the orbital rim, and the zygomaticotemporal nerve is blocked by placing the needle on the concave surface of the posterior lateral orbital rim (see Figure 4). Somatomotor innervation of the orbicularis oculi, frontalis, procerus, and corrugator supercili is supplied by the facial nerve (CNVII). Zygomaticofacial Nerve.

The bilateral absence of the ZFb and the ZFF was found in an 80-year-old Caucasian cadaver. Small aperture of the lateral surface foramen, for the passage of the zygomaticofacial nerve and vessel. The zygomaticofacial foramen, located at the mid-lateral surface of the zygomatic bone that gives off the zygomaticofacial nerve and zygomaticofacial vessels, has also been found to vary from being double or being absent. ZFN-innervated limits were rectangular and each side was 18.8 +/- 4 mm and 15.8 +/- 3.4 mm. The zygomaticotemporal canal likewise . The zygomaticofacial branch (ZFb) of the zygomatic nerve passes through the lateral wall of the orbit anterolaterally and traverses the zygomaticofacial foramen (ZFFOUT). The zygomatic nerve may be disrupted when elevating periorbita from the lateral wall during orbital surgery, and care should be taken to prevent injury to this nerve during lateral orbitotomy approaches to access intraorbital soft-tissue tumors.

Diagnosis is made by physical examination of the temporal fossa and the temporomandibular joint, and injection of local anesthetic over the tenderest nerve. It joins with the facial nerve and with the inferior palpebral branches . Infraorbital and zygomaticofacial branches. As discussed above, innervation to the muscles of the eyelid is via the facial nerve (orbicularis oculi), oculomotor nerve (levator palpebrae superioris) and sympathetic fibres (superior tarsal muscle). hard palate and palatal gingiva/mucosa, between canines. The clinical results of the research allow us to confirm that the upper part of the buccal area may be also innervated by zygomaticofacial nerve. of the zygomaticofacial nerve according to a technique, in which the anesthetic is injected at the lower outer edge of the orbit [8-10] where the zygomaticofacial fo-ramina is located and where the branches of the zygo-maticofacial nerve go outside the zygomatic bone [11].

It supplies a cutaneous . function and location In human nervous system: Maxillary nerve infraorbital, zygomaticotemporal, and zygomaticofacial nerves, serving the upper lip, the lateral surfaces of the nose, the lower eyelid and conjunctiva, and the skin on the cheek and the side of the head behind the eye. Keywords: anesthetic blockade; facial pain; terminal branch neuralgia; trigeminal nerve; zygomaticofacial nerve; zygomaticofacial neuralgia. It helps relay sensation and pain messaging from the upper teeth, jaw, the mucosa (membranes) of the nasal cavity, as well as part of the tongue . The zygomaticofacial nerve is the more ventral branch, which runs rostrally in the orbit deep to the periorbita to emerge medial to the orbital ligament , where it curls dorsally on the external surface of the temporalis muscle.
