The zygomatic nerve is a branch of the maxillary nerve (itself a branch of the trigeminal nerve (CN V)). It arises in the pterygopalatine fossa and enters the orbit through the inferior orbital fissure before dividing into its two terminal branches: the zygomaticotemporal nerve and zygomaticofacial nerve .
Through its branches, the zygomatic nerve provides sensory invervation to skin over the zygomatic bone and the temporal bone . It also carries post-ganglionic parasympathetic axons to the lacrimal gland .
It may be blocked by anaesthetising the maxillary nerve .
Structure [ edit ]
The zygomatic nerve is a branch of the maxillary nerve (CN V2 [1] [2] pterygopalatine ganglion .[1]
It exits from the pterygopalatine fossa through the inferior orbital fissure to enter the orbit .[1] [3] [3]
Branches [ edit ]
Soon after the zygomatic nerve enters the orbit, it divides into its branches. These include:
Variation [ edit ]
Sometimes, the zygomatic nerve does not branch within the orbit. Instead, it enters a single foramen in the zygomatic bone called the zygomatico-orbital foramen . In this case, it divides within the bone into the zygomaticotemporal nerve and the zygomaticofacial nerve .[4]
Function [ edit ]
The terminal branches of the zygomatic nerve contain sensory axons.[1] skin over the temporal bone and the zygomatic bone .[4]
The zygomatic nerve also carries postganglionic parasympathetic axons .[1] cell bodies in the pterygopalatine ganglion . They travel from the ganglion to the zygomatic nerve, and then to the lacrimal nerve through a communicating branch. From the lacrimal nerve, they enter the lacrimal gland and provide secretomotor supply.[5]
Clinical significance [ edit ]
The zygomatic nerve can be blocked indirectly by anaesthetising the maxillary nerve (CN V2 [2] fracture to the zygomatic bone .[6]
