What Is Dacryocystorhinostomy (DCR)?

Dacryocystorhinostomy, or DCR, is a surgical procedure that creates a new drainage pathway between the lacrimal sac and the nasal cavity. It bypasses a blocked nasolacrimal duct so tears can drain into the nose instead of overflowing onto the cheek. DCR is usually done to treat chronic tearing, recurrent eye infections, or pain from a blocked tear duct. The goal is to restore more normal tear flow and reduce symptoms.

Why Is Dacryocystorhinostomy Done?

DCR is recommended when the tear drainage system is blocked and simpler treatments have not solved the problem. People often report constant tearing, sticky discharge, or repeated infections of the lacrimal sac, called dacryocystitis. These issues can affect comfort, appearance, and sometimes vision. Surgery is done to open a new route for tears so the eye stays healthier and more comfortable.

How Is Dacryocystorhinostomy Performed?

DCR can be done through a small skin incision near the inner corner of the eye, called external DCR, or from inside the nose using endoscopic instruments. In both methods, the surgeon removes a small piece of bone and connects the lacrimal sac to the nasal cavity to create a new opening. A tiny tube is often placed temporarily in the tear drainage system to keep the passage open while healing occurs. The procedure is usually done under local anesthesia with sedation or under general anesthesia.

What Is Recovery Like After DCR?

After DCR, mild pain, swelling, or bruising near the inner corner of the eye and nose is common for a few days. Patients may use cold compresses, prescribed eye drops, and nasal sprays to support healing and control discomfort. Most people return to light daily activities within a few days but avoid heavy lifting, nose blowing, or strenuous exercise until the surgeon approves. Follow up visits let the surgeon check the new passage and remove tubes when healing is stable.

Why Do You Need to Care About Dacryocystorhinostomy (DCR)?

Dacryocystorhinostomy, or DCR, is a procedure that creates a new drainage pathway for tears when the usual tear duct route is blocked. It is not a disease label. It is a treatment step used when tearing, recurrent infection, or tear sac swelling keeps coming back because drainage cannot clear properly.

DCR matters because persistent blockage can lead to repeated irritation, discharge, and infections that are hard to control with drops alone. A clear explanation of the goal, recovery timeline, and follow-up plan helps set expectations before surgery. If tearing keeps returning, discharge develops, or the inner corner stays swollen, that is the time to discuss whether DCR fits your situation.

Frequently Asked Questions About Dacryocystorhinostomy (DCR)

Is dacryocystorhinostomy a major surgery?

DCR is a delicate surgery but it is usually done as an outpatient procedure, so most patients go home the same day. The operation is focused on a small area near the inner corner of the eye and nose. Recovery is generally smooth when patients follow post operative instructions and attend follow up visits.

Will I have a visible scar after external DCR?

External DCR uses a small incision near the side of the nose, and this usually heals as a fine line that is hard to notice over time. Surgeons often place the cut in a natural skin crease to help it blend in. Endoscopic DCR done through the nose does not leave a visible skin scar.

How long do the results of DCR last?

For many patients, DCR gives long lasting relief from tearing and infections. Long term success depends on healing, control of any nasal disease, and the cause of the original blockage. If the new opening narrows later, your surgeon might suggest minor procedures to reopen it.

What happens if a blocked tear duct is not treated?

A blocked tear duct can lead to constant tearing, recurrent eye and tear sac infections, and discomfort. In severe or repeated infections, the lacrimal sac can become painful and swollen. Treating the blockage with DCR or other methods helps lower these risks and protect eye health.
