What is Nasolacrimal Duct Obstruction?
The nasolacrimal duct plays a crucial role in draining tears from the eyes into the nasal cavity. When this duct becomes blocked, it results in epiphora, an abnormal overflow of tears, which can lead to discomfort, inflammation, and infection if left untreated. Treating nasolacrimal duct obstruction is similar to calling a plumber to fix a clogged drainage system at home—restoring proper tear drainage is key to maintaining eye health.
In the past, nasolacrimal duct obstruction was considered a non-urgent condition. However, modern ophthalmology has shown that leaving this condition untreated for a long time can lead to recurring infections and severe complications.
Current Surgical Methods for Treating Nasolacrimal Duct Obstruction
1. External Dacryocystorhinostomy (External DCR)
This traditional surgical method has been widely practiced for over 100 years. It involves creating an external incision between the inner corner of the eyelid and the nose to bypass the blocked duct. External DCR offers a high success rate of around 95%, making it a trusted procedure among ophthalmologists. However, the downside of this method is that it leaves a scar on the face, and the recovery time is longer compared to the endoscopic method.
2. Endoscopic Dacryocystorhinostomy (Endoscopic DCR)
Endoscopic DCR is a modern surgical technique that uses a small 4-mm endoscope to access the blocked duct without making an external incision. The surgeon creates a new passage to restore tear drainage, ensuring that the tears can flow normally into the nasal cavity. This method has gained popularity due to its numerous advantages, including:
- No visible scars on the face
- Faster recovery time
- Less tissue disruption and swelling
- High success rate of 98-99% when performed by experienced surgeons
Despite its benefits, endoscopic DCR requires specialized training and significant experience to achieve the best outcomes.
