The zygomatic nerve ( Os zygomaticum " cheekbone ") is a branch of the maxillary nerve , which in turn is a branch of the fifth cranial nerve ( trigeminal nerve ). It sensitively supplies the skin of the temporal region , the zygomatic arch and the eyelids .
The zygomatic nerve branches off from the maxillary nerve in the pterygopalatine fossa , runs through the inferior orbital fissure into the eye socket and divides there into the zygomaticotemporal nerve and the zygomaticofacial nerve . At the pterygopalatine ganglion , the originally purely sensitive nerve receives postganglionic parasympathetic fibers that originate from the seventh cranial nerve and which it transmits to the lacrimal nerve via a connecting branch.
The zygomatic nerve must not be confused with the zygomatic branches of the parotid plexus .
