Anterior lacrimal crest
The anterior lacrimal crest is a bony projection on the frontal process of the maxilla continuous with the orbital rim which creates the lateral margin of the lacrimal sac fossa. The medial palpebral ligament is attached to anterior lacrimal crest.
Immediately anterior to the anterior lacrimal crest, there is a small groove called "sutura notha". It contains a small branch of infraorbital artery which can potentially cause significant bleed if it is cut inadvertently during dissecting this region.
