# What is dacryocystorhinostomy?

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
