Definition[Bearbeiten]
The nasolacrimal duct is a part of the lacrimal apparatus and belongs to the draining lacrimal ducts.
Anatomy[Bearbeiten]
The nasolacrimal duct has a length of 20 to 25 mm and connects the lacrimal sac with the inferior nasal meatus. Its function is to drain the lacrimal fluid into the nose. The nasolacrimal duct is located in the nasolacrimal canal and opens into the inferior nasal meatus below the inferior turbinate via the Hasner's valve.
If the nasolacrimal duct is blocked, the clinical picture of dacryocystitis develops.
