Endoscopic dacryocystorhinostomy (endoscopic DCR) is a tear duct bypass operation performed from inside the nose using an endoscope. It avoids an external skin incision while creating a new drainage channel from the lacrimal sac into the nasal cavity.
How endoscopic DCR is performed
Using a nasal endoscope, instruments open a window in the bone next to the lacrimal sac and fashion a new passage into the nose. Silicone tubes are often left temporarily to keep the route open while healing occurs.
- Usually done under general anaesthetic in theatre
- Can relieve troublesome watering and recurrent dacryocystitis
- Nasal sprays and rinses support healing after surgery
- Endoscopic checks may be arranged to ensure the opening remains patent
