# External vs Endoscopic Dacryocystorhinostomy DCR

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
