Lacrimal Tubercle

The Lacrimal Tubercle is a small, rounded eminence located in the orbital plate of the maxilla. It is a part of the lacrimal apparatus, which is responsible for the production and drainage of tears in the human body.

Etymology

The term "Lacrimal Tubercle" is derived from the Latin words "lacrima" meaning "tear" and "tuberculum" meaning "small swelling".

Anatomy

The Lacrimal Tubercle is situated on the lacrimal groove of the orbital plate of the maxilla. It is the point of attachment for the lacrimal sac, which collects tears from the lacrimal puncta and drains them into the nasolacrimal duct.

Function

The primary function of the Lacrimal Tubercle is to serve as an anatomical landmark during surgical procedures involving the lacrimal apparatus. It also plays a role in the drainage of tears, as it is the point of attachment for the lacrimal sac.

Clinical Significance

In cases of dacryocystitis, an inflammation of the lacrimal sac, the Lacrimal Tubercle may become swollen and tender. This can lead to tear drainage problems and discomfort. Treatment typically involves antibiotics and, in severe cases, surgical intervention.
