The infraorbital groove (or sulcus) is located in the middle of the posterior part of the orbital surface of the maxilla. Its function is to act as the passage of the infraorbital artery, the infraorbital vein, and the infraorbital nerve.

2019年5月29日 · The infraorbital groove is a bony groove within the maxillary bone located at the posterior 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.

A groove in the infraorbital region (GIR) refers to a narrow furrow around the infraorbital rim, and hollowness of the infraorbital region (HIR) refers to a sunken space in the infraorbital area. Treatments for the correction of GIR and HIR are usually divided into nonsurgical and surgical corrections [ 1 , 2 ].

The infraorbital groove, lies near the middle of the posterior part of the maxilla’s orbital surface, within the orbit, serving as a pathway for the infraorbital nerve and blood vessels. The groove starts midway along the posterior border of the orbital surface, where it is continuous with the anterior surface of infratemporal fossa.

The infraorbital groove (infraorbital sulcus) is the shallow, posteriorly located depression found along the orbital surface of the maxilla. It travels anteriorly from the posterior border of the orbital surface to the infraorbital canal. The infraorbital nerve and vessels pass through this groove.

2025年1月18日 · The infraorbital groove is a shallow, narrow channel that runs horizontally along the infraorbital margin. It is formed by the infraorbital ridge, which is a bony protuberance on the maxilla (upper jaw bone).

A distinctive characteristic is the infraorbital groove situated centrally, which advances forward on the orbital surface to become the infraorbital canal. This canal emerges on the face's front as the infraorbital foramen, facilitating the passage of the infraorbital vessels and nerve.

2024年3月14日 · From the inferior orbital fissure, the infraorbital nerve runs anteriorly along the floor of the orbit in the infraorbital groove. The infraorbital nerve penetrates the maxillary bone through the infraorbital canal at the anterior aspect of the orbit.

After entering the orbit via the inferior orbital fissure (IOF), it usually courses anteriorly through the infraorbital groove and canal. The infraorbital canal is located anteriorly within the orbital floor or superior wall of the maxilla.

The infraorbital nerve (ION) and its canal are important landmarks during surgical approaches to the orbital floor and pterygopalatine fossa. However, variations in the anatomy of the infraorbital canal and its corresponding neurovascular bundle may ...
