External dacryocystorhinostomy: an effective solution to the problem of lacrimation

External dacryocystorhinostomy (d. externa) is a surgical procedure used to treat watery eyes caused by obstruction of the tear ducts on the outer portion of the lacrimal sac. This procedure has a long history and is widely used in ophthalmic practice to remove obstacles that arise in the path from the lacrimal sac to the nose.

Lacrimation is a condition in which tears cannot drain normally from the eyes through the tear ducts, resulting in excess tears and constant or intermittent tearing. Tear duct obstruction can be caused by a variety of factors, including congenital abnormalities, infections, trauma, or tumors. If conservative treatment methods, such as massage of the lacrimal sacs, lavage of the ducts, or the use of medicated drops, do not lead to improvement, external dacryocystorhinostomy may be recommended as a surgical intervention.

The external dacryocystorhinostomy procedure is performed under local anesthesia and usually takes about 30-60 minutes. The surgeon makes a small incision in the corner of the eye and creates a new passage from the lacrimal sac directly into the nasal cavity. This allows the tears to bypass the obstruction in the tear ducts and drain properly. After surgery, it may take some time for the wound to heal.

External dacryocystorhinostomy is generally considered a safe procedure with a high success rate. Patients often notice a significant reduction or complete cessation of tearing after surgery. Additionally, this procedure may help prevent recurrent infections and inflammation associated with the tear ducts.

However, like any surgical procedure, external dacryocystorhinostomy may have some risks and complications, including bleeding, infection, scarring, or damage to surrounding tissue. Therefore, it is important to conduct a preliminary assessment and detailed discussion with an ophthalmologist to determine the indications and possible risks for each specific case.

In conclusion, external dacryocystorhinostomy is an effective and relatively safe procedure for the treatment of lacrimation caused by obstruction of the tear ducts of the external portion of the lacrimal sac. It can significantly improve the quality of life of patients and prevent related problems. If you are experiencing symptoms of watery eyes or other eye problems, it is recommended that you contact a qualified ophthalmologist who will provide the necessary evaluation and recommendations for further treatment.
