Understanding Blocked Tear Ducts
Blocked tear ducts can cause persistent tearing, infections, and discomfort. When tears cannot drain properly, they may overflow onto the face or lead to recurrent eye infections. Dacryocystorhinostomy (DCR) is a surgical procedure designed to restore proper tear drainage by creating a new pathway between the tear sac and the nasal cavity.
What Is Dacryocystorhinostomy (DCR)?
Dacryocystorhinostomy (DCR) is a surgical procedure that bypasses a blocked tear duct. It connects the tear sac directly to the nasal cavity, allowing tears to drain normally. This relieves symptoms like excessive tearing, pain, and infections. Surgeons perform DCR using external or endoscopic techniques based on the patient’s needs.
The DCR Procedure
During DCR, the surgeon creates a small opening between the tear sac and nasal cavity. This allows tears to flow directly into the nose. The procedure typically takes 1 to 2 hours under general anesthesia. Most patients return home the same day or the next.
Benefits and Recovery
DCR successfully restores normal tear drainage and reduces infection risks. After surgery, patients may experience mild swelling or bruising, which usually fades within a week or two. Full recovery takes a few weeks. Patients should avoid strenuous activities and follow post-operative care instructions.
