Endonasal DCR, or Endonasal Dacryocystorhinostomy, is a surgical procedure used to treat obstructed tear ducts. The tear duct system drains tears from the eye into the nasal cavity, and when this system is blocked, it can lead to excessive tearing and potential infections.

In an endonasal DCR, the surgeon creates an opening between the tear sac (located near the inner corner of the eye) and the nasal cavity, but instead of making an external incision, the procedure is performed through the nasal passage. This approach can be less invasive and may result in a faster recovery with less visible scarring compared to traditional external DCR.

The benefits of endonasal DCR include:

• Minimal external scarring
• Reduced postoperative discomfort
• Shorter recovery time

The procedure typically involves:

1. Anesthesia: The patient is usually given general anesthesia or local anesthesia with sedation.
2. Surgical Access: The surgeon accesses the tear duct system through the nasal cavity.
3. Creating the Opening: A small opening is created between the tear sac and the nasal cavity.
4. Placement of a Stent: A temporary stent or tube may be placed to keep the new passage open while it heals.

Postoperative care generally involves managing nasal congestion, avoiding activities that could strain the healing area, and possibly using antibiotics or other medications as prescribed.

Endonasal DCR is generally considered effective, but like all surgeries, it carries some risks and potential complications, so it’s important for patients to discuss these with their surgeon.
