Endoscopic Dacryocystorhinostomy (DCR)

If non-surgical options do not successfully unblock obstructed tear ducts, a Dacryocystorhinostomy (DCR) surgery is performed to create a new path for tears to drain between your eyes and your nose.

A DCR can be performed two ways – externally, by incision through the skin, or endoscopically through the nose, a less invasive approach preferred by many as there are no facial scars and it is less painful.


During an endoscopic DCR, the sinus surgeon works in tandem with an ophthalmic surgeon.

Going through the nasal passage under endoscopic vision, the sinus surgeon creates an opening in the bone that overlies the lacrimal sac.

A connection is then created between the lacrimal sac and your nasal cavity. The eye surgeon usually places a small stent there to help keep the passageway open allowing tears to bypass the blockage.

Your medical team may request tests before the procedure to get a better understanding of your unique anatomy. These might include:

  • CT scan
  • MRI scan

Note:  Not everyone who has a blocked tear duct needs a DCR.  Depending on the cause of the blockage, you may need another treatment. For example, you might need a different kind of surgery if a tumor blocks your duct.
