What passes through the Zygomaticofacial foramen?

What passes through the 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.

What does the zygomaticofacial nerve supply?

The zygomaticofacial nerve runs along the lower outer aspect of the orbit, and arrives onto the surface of the face through a foramen in the zygomatic bone. It then passes through the orbicularis oculi and innervates the skin over the prominence of the cheek.

Which nerve exits through the Zygomaticofacial foramen?

zygomatic nerve
The zygomaticofacial branch (ZFb) of the zygomatic nerve passes through the lateral wall of the orbit anterolaterally and traverses the zygomaticofacial foramen (ZFFOUT).

What does the Zygomaticotemporal nerve innervate?

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 foramen Rotundum?

The foramen rotundum (plural: foramina rotunda) is located in the middle cranial fossa, inferomedial to the superior orbital fissure at the base of greater wing of the sphenoid bone. It transmits the maxillary branch of trigeminal nerve (V2), artery of foramen rotundum, and emissary veins.

What passes through the infraorbital foramen?

The infraorbital foramen, an opening into the floor of the eye socket, is the forward end of a canal through which passes the infraorbital branch of the maxillary nerve, the second division of the fifth cranial nerve.

What is Vidian nerve?

Vidian nerve, also known as the nerve of the pterygoid canal or nerve of the Vidian canal, is so named because of the canal in which it travels: the Vidian canal. It is formed by the confluence of two nerves: deep petrosal nerve (from the sympathetic plexus on the internal carotid artery) carrying sympathetic fibers.

How do you block auriculotemporal nerve?

As classically described, the auriculotemporal nerve block is performed with 5 mL of local anesthetic injected 1.5 cm anterior to the ear at the level of the tragus, being careful to identify the superficial temporal artery (and performing negative aspiration) before injection.

What nerve exits the Infraorbital foramen?

The Maxillary Nerve (V2) It then passes through the orbit in the infraorbital canal, exits through the infraorbital foramen, and gives rise to three cutaneous branches: the zygomaticotemporal, zygomaticofacial, and infraorbital nerves.

What is Auriculotemporal nerve a branch of?

trigeminal nerve
The auriculotemporal nerve is a tributary of the mandibular division of cranial nerve five, the trigeminal nerve. It contains sensory, vasomotor, and parasympathetic fibers.

What nerve passes through foramen lacerum?

greater petrosal nerve
The two nerves that pass from the foramen lacerum are the greater petrosal nerve, which represents the pre-ganglionic parasympathetic fibers, and the deep petrosal nerve which, representing the post-ganglionic sympathetic fibers.

What nerve passes through foramen rotundum?

The maxillary nerve (V2) passes through the foramen rotundum and into the infraorbital canal, where, at the pterygopalatine fossa, it branches into the pterygopalatine ganglion, with parasympathetic and sensory branches to the paranasal sinuses.
