Endoscopic DCR (Dacryocystorhinostomy)

In Endoscopic DCR, the procedure is performed through the nasal cavity, without the need for external incisions. The process involves the following steps:

• Preoperative Assessment: The patient undergoes a thorough examination, including imaging studies such as CT scans or dacryocystography to assess the site and extent of the obstruction. This imaging helps the surgeon plan the surgical approach with precision.
•  
• Anesthesia: The surgery is typically performed under local anesthesia with sedation or general anesthesia, depending on the patient’s preferences and the complexity of the surgery.
• Endoscopic Access: A thin, flexible endoscope (a small tube with a camera and light) is inserted through the nostrils to provide the surgeon with a clear view of the lacrimal sac and the obstructed tear duct.
• Creation of New Drainage Pathway: Using specialized instruments, the surgeon removes the obstructed portion of the nasolacrimal duct and creates a new opening from the lacrimal sac into the nasal cavity. This allows tears to drain properly into the nose, bypassing the blockage.
• Postoperative Care: The procedure typically involves placing a stent or silicone tube temporarily to keep the new passage open during healing. The stent is usually removed after a few months. Patients are advised to follow up for regular check-ups to ensure the new drainage pathway is functioning correctly.
