Infraorbital groove
Sulcus infraorbitalis
Definition
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. Moving forward, it transits into the infraorbital canal. The orbitalis muscle, extending from the inferior orbital fissure, covers the groove.
