The anterior lacrimal crest is a bony projection on the frontal process of maxilla in the skull. It creates the lateral margin of the lacrimal sac fossa and is continuous with the orbital margin. At its junction with the orbital surface is a small tubercle, the lacrimal tubercle, which serves as a guide to the position of the lacrimal sac.The medial palpebral ligament is attached to anterior lacrimal crest.
