Notes | |
The lacrimal hamulus is a small hook-like projection located on the lacrimal bone, which is part of the orbital structure of the skull. It plays a role in the tear drainage system by supporting the lacrimal sac.
Anatomy[edit | edit source]
The lacrimal hamulus is situated at the junction of the lacrimal groove and the nasolacrimal canal. It is a part of the medial wall of the orbit and contributes to the formation of the lacrimal fossa.
Function[edit | edit source]
The primary function of the lacrimal hamulus is to provide structural support to the lacrimal apparatus, particularly the lacrimal sac, which is essential for the proper drainage of tears from the eye into the nasal cavity.
Clinical significance[edit | edit source]
In some cases, the lacrimal hamulus can be involved in nasolacrimal duct obstruction, which can lead to epiphora (excessive tearing) or dacryocystitis (inflammation of the lacrimal sac). Surgical procedures involving the lacrimal system, such as dacryocystorhinostomy, may require careful consideration of the lacrimal hamulus.
