Endoscopic dacryocystorhinostomy (DCR) is a surgical procedure used to treat a blocked tear duct. This minimally invasive approach involves using an endoscope, a thin, flexible tube with a camera attached, to visualize and access the tear duct and surrounding structures. The surgeon makes a small incision inside the nasal cavity to create a new opening between the tear sac and the nasal passage, bypassing the obstruction. This allows tears to drain freely, relieving symptoms such as excessive tearing, recurrent infections, and eye discomfort.
Compared to traditional DCR, which requires external incisions, endoscopic DCR offers several advantages. It results in less scarring, reduced postoperative pain, faster recovery, and a lower risk of complications. Additionally, because it is performed entirely through the nostrils, there is no visible scarring on the face.
Endoscopic DCR is typically performed under general anesthesia and may be done on an outpatient basis, meaning patients can return home the same day. Following the procedure, patients may experience mild discomfort, nasal congestion, or temporary changes in nasal drainage, which typically resolve within a few days to weeks.
