Dacryocystorhinostomy (DCR) is surgery to bypass a blocked nasolacrimal duct by creating a new drainage channel between the tear sac and the nose. It is performed for adults with persistent watery eyes and recurrent infections due to tear duct obstruction.
External and Endoscopic Approaches
In external DCR, a small incision is made on the side of the nose to access the tear sac and create a direct opening into the nasal cavity. Endoscopic DCR uses instruments through the nostril, avoiding a skin incision, with the same goal of forming a patent passage.
- Soft silicone stents are often placed temporarily to keep the new channel open
- Choice of approach depends on anatomy, surgeon experience, and patient preference
- Both techniques have high long-term success rates
- General or local anaesthetic with sedation may be used
Recovery
Bruising, swelling, and nasal congestion are common for a short time after surgery. Most patients notice significant reduction in watering once healing is complete.
- Nasal rinses and prescribed drops help maintain patency
- Blowing the nose forcefully is avoided in the early period
- Follow-up visits check stents and healing of the osteotomy site
- Persistent or recurrent watering may occasionally need revision surgery
