Dacryocystorhinostomy is a type of surgery sometimes used to treat blocked tear ducts in adults. It is rarely used in children.
This procedure creates a new passageway between the tear duct sac and the nasal cavity, bypassing the blocked tear duct. To do the procedure, the doctor needs to make a cut (incision) in the skin by the eye. A tube is inserted through the tear duct sac and into the nose through a hole in the bone. This tube is left in the nose and stitched in place.
If you notice soft or hard yellow patches on the inside corners of your eyelids, you might have xanthelasma. They're made up of cholesterol that's under your skin. They aren't harmful, but if you're bothered by the way they look, there are treatments that can get rid of them.
Even though xanthelasma itself won't hurt you, it could be a sign that you're at higher risk for heart disease. So don't ignore this skin condition. Get it checked by your doctor.
Adults who have long-term tear duct blockage that is not caused by an infection often need to have dacryocystorhinostomy. If the person has a tear duct infection, surgery will be delayed until the infection has cleared.
