The zygomatic branches of the facial nerve (malar branches) are nerves of the face. They run across the zygomatic bone to the lateral angle of the orbit. Here, they supply the orbicularis oculi muscle, and join with filaments from the lacrimal nerve and the zygomaticofacial branch of the maxillary nerve (CN V 2).
The temporal branch of the facial nerve is typically found between the temporoparietal fascia (i.e., superficial temporal fascia) and temporal fascia (i.e., deep temporal fascia). This layer is also known as the innominate fascia. There are several methods using anatomic landmarks that may be used to find the temporal branch of the facial nerve.
The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.

The zygomaticofacial nerve penetrates [dubious – discuss] 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.
Thus the facial artery can be used as an important landmark in locating the marginal mandibular nerve during surgical procedures. [2] Damage can cause paralysis of the three muscles it supplies, which can cause an asymmetrical smile due to lack of contraction of the depressor labii inferioris muscle . [ 3 ]
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 .
The facial nerve exits the cranial cavity through the internal acoustic meatus and enters the facial canal. In the facial canal, the chorda tympani branches off the facial nerve and enters the lateral wall of the tympanic cavity inside the middle ear where it runs across the tympanic membrane (from posterior to anterior) and medial to the neck ...
