Abstract

The lacrimal sac and upper part of the NLD is housed in the bony lacrimal fossa or the sulcus lacrimalis which is bounded anteriorly and posteriorly by the respective lacrimal crests [1–5]. Anterior lacrimal crest is a bony projection of the frontal process of maxilla and continues inferiorly as the inferior orbital margin, whereas posterior lacrimal crest is a projection of the lacrimal bone and ends inferiorly by curving as a small hook. The bony lacrimal fossa continues downward as the nasolacrimal canal, which is formed by the maxilla, lacrimal bone, and the inferior nasal concha and transmits the nasolacrimal duct, which opens into the inferior meatus.
