infraorbitalartären

The infraorbital artery is a blood vessel in the face. It is a terminal branch of the maxillary artery. The infraorbital artery exits the infraorbital foramen, which is an opening in the maxilla bone below the orbit of the eye.

As it emerges from the foramen, the infraorbital artery divides into several branches. These branches supply blood to the muscles of the upper lip and nose, as well as the skin of the lower eyelid and side of the nose. Some of these branches also contribute to the blood supply of the maxillary teeth and gums.

The infraorbital artery plays a role in facial sensation and movement. Its branches are involved in the innervation of muscles responsible for facial expressions, and the artery itself is important for delivering oxygen and nutrients to these tissues. Understanding the anatomy and branching pattern of the infraorbital artery is crucial for surgeons performing procedures in the midface region, such as rhinoplasty or orbital surgery. Damage to this artery can lead to bleeding or impaired function of the surrounding facial structures. Its position makes it vulnerable to trauma in the infraorbital area.
