Endoscopic dacryocystorhinostomy (DCR)

This surgery is a way to improve tear discharge by creating a new lacrimal duct in the nose and bypassing the obstruction that exists. This is usually done under anesthesia (and without hospitalization).
DCR surgery involves opening the existing lacrimal sac and attaching it directly to the nose to create a new outlet for tears. This requires a small portion of the nasal bone, located between the lacrimal sac and the nose to be removed. The lacrimal sac is accessible through the nose(Endonasal) or through the skin between the eyes and nose. There are two types of DCR surgery:
  • External DCR
  • Endoscopic DCR

Endoscopic DCR:
This type of procedure is a less invasive way to open the lacrimal duct. This is very similar to External DCR, except that no cut is applied to the skin and no scars remain after the operation. In this way, the surgeon can access the nose through a small, thin endoscope camera. As with other DCR surgeries, a thin tube is inserted into the nose to keep the newly created duct open and not obstructed. This tube is also removed 4 to 6 weeks after surgery.
