Anatomical terms of bone [[[d:|edit on Wikidata]]]

Not to be confused with the inferior orbital fissure, which is just lateral to the infraorbital groove.

Also not to be confused with the infraorbital canal, into which the groove enters, nor the infraorbital foramen, which is the canal's opening on the other side.

Near the middle of the posterior part of the orbital surface of the maxilla is the infraorbital groove (or sulcus), for 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.
