Nasolacrimal - related to the nose and lacrimal apparatus. This term is used to describe the anatomical and functional connections between the nose and the lacrimal glands, which are part of the lacrimal apparatus.
The lacrimal apparatus plays an important role in protecting the eyes from external influences such as dust, germs and other irritants. It also helps moisturize and cleanse the surface of the eye for optimal vision. However, if the tear duct is not functioning properly, it can lead to various problems such as dry eyes, irritation and even infections.
In order to understand how the nasolacrimal duct works, it is necessary to consider its anatomy. The lacrimal glands are located in the upper outer part of the eye socket and produce tear fluid. This fluid is secreted into the lacrimal openings, which are located in the corners of the eyes and then flows down the lacrimal ducts into the nasal cavity.
The nasolacrimal duct begins at the lacrimal puncta and passes through the bones of the face and nasal passages to open into the nasal cavity. This channel is important for draining tear fluid from the eyes into the nose, which helps maintain normal vision and prevent infections.
However, sometimes the nasolacrimal duct can become blocked, causing tear fluid to be retained in the eyes. This can happen due to many reasons, such as malformation of the canal, infection or injury. In such cases, surgery may be required to remove the blockage and restore normal tear flow.
In conclusion, the nasolacrimal duct plays an important role in maintaining eye health and preventing infections. Understanding its anatomy and function helps in diagnosing and treating various tear problems. If you have problems with your tear system, see an ophthalmologist for diagnosis and treatment.
The nasolacrimal duct, or nasolacrimal duct (lat. ductus nasolacrimalis) is a canal that connects the nasal cavity with the preauricular region (a pocket located in the upper part of the cheek) and then with the lacrimal duct.
This canal is formed by the fusion of the lacrimal canal with the nasolacrimal canal at the entrance to the nose. There is an opening in the mucous membrane of the nasal septum through which the nasolacrimal duct opens to the outside.
The nasolacrimal duct is important for the functioning of the lacrimal system. It ensures the outflow of tears from the lacrimal sacs into the preauricular area, where it mixes with the secretion of the salivary glands and flows into the oral cavity. Thus, the nasolacrimal duct plays an important role in keeping the eyes clean and protected from infections.
However, in some cases, the nasolacrimal duct may become blocked or blocked. This can lead to the development of various diseases, such as dacryocystitis (inflammation of the lacrimal sac), dacryostenosis (narrowing of the nasolacrimal duct) and others.
Various methods are used to diagnose and treat nasolacrimal duct diseases, including endoscopy, radiography, and surgery. One of the most common treatments is nasolacrimal duct lavage, which removes excess mucus, clears the duct and restores its normal function.
Overall, the nasolacrimal duct is an important part of the lacrimal system and plays an important role in protecting the eyes from infections and keeping them clean. However, its blockage or obstruction can lead to various diseases, so it is necessary to undergo regular examination by an otolaryngologist and, if necessary, undergo treatment.
