The lacrimal bone (os lacrimale) is paired and forms the anterior part of the medial wall of the orbit. Below and in front, it is connected to the frontal process of the maxilla, and behind - to the orbital plate of the ethmoid bone. Above, the lacrimal bone borders on the medial edge of the orbital part of the frontal bone. On the lateral surface of the bone is the posterior lacrimal crest (crista lacrimalis posterior). Anterior to the lacrimal crest is the lacrimal groove (sulcus lacrimalis), which, together with the groove of the same name in the maxilla, forms the fossa of the lacrimal sac (fossa lacrimalis).
