Where is infraorbital area?

The infraorbital region is a component of the midface and can be defined as the anatomical area between the nasal aperture and the zygomatic bone below the inferior rim of the orbit and above the roots of the maxillary canine and premolars (Fig. 6.1).

What is the infraorbital nerve used for?

The infraorbital nerve supplies sensory innervation to the lower eyelid, the side of the nose, and the upper lip (see image below). Since the infraorbital nerve provides a considerably large area of sensory innervation, it is a prime candidate for a regional nerve block.

What is the infraorbital canal?

The infraorbital canal is a bony canal within the maxillary bone located at the anterior aspect of the orbital floor. It transmits the infraorbital nerve, which is a branch of the maxillary division of the trigeminal nerve (CN Vb), as well as the infraorbital artery and vein.

What is the infraorbital injection?

Infraorbital nerve block is a type of anesthesia used for numbing parts of the face. There is an infraorbital nerve on each side of the face, which is responsible for sensation to the skin on the side of the face, of the lower eyelid, the side of the nose, and the upper lip.

What is a Supraorbital?

Definition of supraorbital : situated or occurring above the orbit of the eye.

Where is the infraorbital margin located?

the eye socket
The infraorbital margin is the lower margin of the eye socket. It consists of the zygomatic bone and the maxilla, on which it separates the anterior and the orbital surface of the body of the maxilla. It is an attachment for the levator labii superioris muscle.

What is infraorbital artery?

Infraorbital artery (IOA) is the branch of the maxillary artery. It appears in pterygopalatone fossa as a branch of third part of maxillary artery. It enters the orbit through inferior orbital fissure traveling anteriorly through infraorbital groove and infraorbital canal.

What is infraorbital a branch of?

The infraorbital nerve (ION) is the terminal branch of the maxillary nerve; it supplies the skin and mucous membranes of the middle portion of the face. This nerve is vulnerable to injury during surgical procedures of the middle face.

Where is the infraorbital nerve on the face?

The infraorbital nerve supplies sensation to the skin of the cheek, the upper lip, the lateral aspect of the nose, and the ipsilateral upper teeth. This nerve is located at the mid-pupillary line approximately 7 mm below the infraorbital rim.

What is an infraorbital block?

What nerve does an infraorbital block anesthetize?

Answer. An infraorbital nerve block, which branches from the maxillary nerve, anesthetizes the lower eyelid, upper cheek, part of the nose, and upper lip (see image below).

Where is the supraorbital?

The supraorbital foramen or notch is the small opening at the central edge of the superior orbital margin in the frontal bone just below the superciliary arches that transmits the supra-orbital nerve, artery and vein.

What is infraorbital margin?

The infraorbital margin is the lower margin of the eye socket.

What does the infraorbital artery come off of?
