Left maxilla. Outer surface. (Infra-orbital groove labeled at upper right.)
|Latin||Sulcus infraorbitalis maxillae|
|Anatomical terms of bone|
Not to be confused with the inferior orbital fissure, which is just lateral to the infraorbital groove.
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 vessels and nerve.
The groove begins at the middle of the posterior border (with which it is continuous) near the upper edge of the infratemporal surface and, passing forward, ends in a canal which subdivides into two branches.
