What is Zygomaticotemporal suture?
The zygomaticotemporal suture (or temporozygomatic suture) is the cranial suture between the zygomatic bone and the temporal bone. This is part of the zygomatic arch. Movement at the suture decreases with development during aging. It has a complex internal structure.
What does the zygomaticotemporal nerve supply?
The zygomaticotemporal nerve, arising from the maxillary division of the trigeminal nerve, innervates the skin of the temple region. The auriculotemporal nerve, derived from the mandibular division of the trigeminal nerve, innervates the posterior portion of the skin of the temple.
What is a Zygomaticofacial foramen?
The zygomaticofacial foramen is a small foramen in the mid lateral surface of the zygomatic bone that transmits the zygomaticofacial nerve (a branch of the zygomatic nerve from the maxillary division of the trigeminal nerve) and zygomaticofacial vessels.
Which nerve exits through the zygomaticofacial foramen?
The zygomaticofacial branch (ZFb) of the zygomatic nerve passes through the lateral wall of the orbit anterolaterally and traverses the zygomaticofacial foramen (ZFFOUT).
Where is zygomaticofacial foramen located?
zygomatic bone
Results: Zygomaticofacial foramina are very frequent structures which tend to appear singly. They are generally located in the temporal process of the zygomatic bone, but in many cases, they may be located in the mid portion of the bone.
Where is the occipitomastoid suture?
The occipitotemporal or occipitomastoid suture is the obliquely oriented articulation of the anterior border of the squamous occipital bone and the mastoid portion of the temporal bone. A mastoid foramen is occasionally located near or in it.
What is the zygomaticotemporal suture?
The zygomaticotemporal suture (or temporozygomatic suture) is the cranial suture between the zygomatic bone and the temporal bone. This is part of the zygomatic arch.
What is the zygomaticotemporal nerve?
The zygomaticotemporal nerve is a branch of the zygomatic nerve (seeFig. 8.87, p. 922 ). The zygomatic nerve is a branch of the maxillary nerve [V 2 ], which originates in the pterygopalatine fossa and passes into the orbit.
Where does the zygomatic nerve enter the orbit?
The zygomatic nerve starts within the pterygopalatine fossa and enters the orbit via the inferior orbital fissure dividing into two named branches, that is, zygomaticotemporal and zygomaticofacial nerves. The zygomaticotemporal nerve runs along the lower outer aspect of the orbit and provides a branch to the lacrimal nerve.
Where is the auriculotemporal nerve located?
The auriculotemporal nerve arises from the posterior trunk of the mandibular division of the trigeminal nerve. Nerve block for this nerve can be performed at the level of and 10-15 mm anterior to the upper origin of the helix of the ear.
