External and endoscopic dacryocystorhinostomy are two surgical ways of bypassing a blocked tear duct to relieve constant watering and infections.
How these operations differ
Both procedures create a new passage from the tear sac into the nose so tears can drain properly again. The main difference is the route the surgeon uses to reach the tear sac.
- External DCR uses a small cut in the skin beside the nose
- Endoscopic DCR is performed from inside the nose using a tiny camera
- Both may use soft silicone stents while the new passage heals
- Choice depends on your anatomy, other nasal issues, and surgeon expertise
Which approach might suit you
External DCR offers excellent long term success and allows the surgeon direct access to the tear sac. Endoscopic DCR avoids a visible scar and can be combined with other nasal procedures if needed.
- External DCR may leave a fine scar that usually fades well over time
- Endoscopic DCR may cause more nasal congestion and crusting early on
- Recovery from either procedure typically takes a couple of weeks
- Your surgeon will explain personal risks, benefits, and expected comfort
