What is Endonasal Dacryocystorhinostomy?

What is Endonasal Dacryocystorhinostomy?

Dacryocystorhinostomy (DCR) involves the creation of an alternative route for the drainage of tears between the lacrimal sac and nasal cavity, bypassing the nasolacrimal duct. This alternative route is generated using an external approach (external DCR) or through the nasal cavity using an endoscope (EES-DCR).

What causes Dacryocystorhinostomy?

The most common cause of failed endonasal dacryocystorhinostomy (DCR) is membranous obstruction. Lacrimal silicone tube intubation is effective treatment method for functional epiphora.

How long does a Dacryocystorhinostomy take?

What is a dacryocystorhinostomy (DCR)? A DCR is a type of surgery that is used to treat blocked tear ducts in adults. It creates a new passageway between the tear duct sac and the nose, bypassing the blockage and allowing tears to drain normally again. The operation usually takes about 1 hour.

What is endoscopic Dacryocystorhinostomy?

Endoscopic dacryocystorhinostomy (DCR) is a widely performed and safe procedure for the treatment of nasolacrimal duct obstruction manifested as epiphora or dacryocystitis. Current success rates are above 90%. Data on causes for failure of the procedure are sparse.

Which bone is removed in Dacryocystorhinostomy?

During the creation of the bony ostium as part of endoscopic DCR surgery, the uncinate process helps define the posterior-inferior extent of bone removal involving the lacrimal bone covering the lacrimal sac. Once the uncinate process is encountered, further ostium creation can extend upwards.

How do they remove an eye stent?

Monoka stents are removed by cutting any sutures that hold the stent in place and then pulling the stent out of the punctum with forceps. Jones tubes are removed by cutting the suture that is wrapped around the tube (if one is present) and then pulling out the tube with forceps.

What is the best treatment for a blocked tear duct?

For adults with partially narrowed puncta, your doctor may dilate the puncta with a small probe and then flush (irrigate) the tear duct. This is a simple outpatient procedure that often provides at least temporary relief. Stenting or intubation. This procedure is usually done using general anesthesia.

How do you do Dacryocystorhinostomy?

DCR Through the Skin (External Procedure) The surgeon makes a small incision in the skin, in the area under your eye and next to your nose. Through this incision, your surgeon creates a small opening in the bone beneath. This opening then connects your lacrimal sac and your nasal cavity.

Are eye stents permanent?

The fluid is reabsorbed from the bleb by the tissues and veins around it. With a successful Xen stent, the fluid pressure within the eye is often lowered for several years. The duration of success depends on the patient’s age, type of glaucoma, and many other factors.

How successful is Dacryocystorhinostomy surgery?

It can be performed via the skin (external DCR) or intranasally (endonasal DCR). External DCR has usually been performed because of the accessible location of the lacrimal sac and its high success rate, approximately 90–96 %.

How painful is tear duct surgery?

Your child should have very little discomfort after the procedure. It’s common for kids to have some bloody or pink-tinged tears and a mild bloody nose for the first 1–2 days after the procedure. The doctor may prescribe eye drops after surgery and will tell you how to care for your child at home.

The effect appears to be durable for at least 24 months. The Hydrus maintained significant reductions in medications and IOP.

How successful is stent surgery for glaucoma?

In a U.S. clinical study, 68% of glaucoma patients who received iStent remained medication-free at 12 months while sustaining a target IOP of ≤ 21 mm Hg vs. only 50% of patients who underwent cataract surgery alone. iStent works like the stents used to prevent heart attacks and strokes.
