Introduction
Tear duct surgery is a procedure performed to treat blocked tear ducts, also known as nasolacrimal duct obstruction. The tear drainage system consists of small ducts that allow tears to flow from the eyes into the nose. When these ducts become blocked, it can lead to a condition called epiphora, which is characterized by excessive tearing or watery eyes. For many suffering from chronically blocked tear ducts, tear duct surgery provides an effective solution.
Tear duct surgery, also referred to as dacryocystorhinostomy or DCR, aims to restore normal tear drainage by creating a new opening from the tear drainage system into the nose. This allows tears to bypass the blocked part of the duct and drain down the back of the throat as intended. There are a variety of surgical approaches that may be used depending on the individual case. Most procedures involve making an incision either along the side of the nose or inside the nasal cavity to access the tear ducts and nasal cavity.
The primary benefit of tear duct surgery is relief from chronic epiphora. By re-establishing drainage, tears can finally empty through their intended pathway instead of overflowing onto the cheek. This surgery has high long-term success rates and significantly improves quality of life for those with nuisance tearing issues. Though there are risks involved, tear duct surgery can be life-changing for individuals struggling with chronically blocked tear ducts when conservative treatments fail to provide adequate relief.
Causes and Symptoms of Blocked Tear Ducts
Blocked tear ducts, also called nasolacrimal duct obstruction, can occur for a number of reasons. Some common causes include:
• Injury to the nose or face – trauma from an accident or surgery can damage the delicate nasal bones and duct system.
• Scar tissue – scarring on the inside of the nasal cavity or in the tear drainage pathways may obstruct or narrow ducts.
• Infection – sometimes chronic inflammation/infection causes swelling and mucus buildup that blocks drainage.
• Congenital defect – some babies are born with abnormally developed or missing tear ducts.
• Age-related changes – our tear drainage system can lose function as it weakens with age.
No matter the underlying cause, a blocked tear duct prevents tears from draining normally, leading to backup and overflow. The main symptom is epiphora, which is excessive tearing or watery eyes. Other signs and symptoms include:
• Tears spilling over the eyelids and onto the cheeks
• Crusting of tears on the lashes and skin around the eyes
• Redness and irritation of the skin near the eye
• Recurrent eye infections
• Swelling at the inner corner of the eye or side of the nose
• Pain and tenderness around the nose and cheek area
Diagnosing Blocked Tear Ducts
If excessive tearing is interfering with daily life, the first step is getting an evaluation by an ophthalmologist or optometrist. The eye doctor will perform a clinical eye exam looking for signs of blocked tear drainage. They may ask about symptoms and use magnification and light to inspect the drainage structures around the eye and nose.
If a blocked tear duct is suspected, some common diagnostic tests include:
• Tear duct irrigation – Flushing fluid through the drainage system checks if there is adequate flow and drainage into the nose. Most blockages prevent irrigation fluid from reaching the throat.
• Dacryocystography – This imaging test involves injecting dye into the tear duct system and taking x-rays or CT scans to get an image of the drainage structures. Blockages and obstructions are clearly highlighted.
• Nasal endoscopy – A tiny fiberoptic camera is inserted into the nasal cavity allowing the doctor to visually inspect for narrowed duct openings, scarring, polyps, or other abnormalities obstructing tear drainage.
• Tear duct probing – Inserting a small probe into the nasolacrimal duct assesses the location and extent of any blockage.
Once diagnosed with a blocked tear duct, an ophthalmologist will recommend treatment options tailored to the specific case and symptoms. This may include tear duct surgery if conservative treatments prove inadequate at relieving epiphora.
Tear Duct Surgery Options
For cases of blocked tear ducts that fail to respond to conservative treatments, tear duct surgery (dacryocystorhinostomy or DCR) is often recommended. This procedure aims to bypass the blocked drainage pathway by creating a new opening from the tear sac directly into the nasal cavity.
Some surgical approaches include:
• External dacryocystorhinostomy – The most common approach where an incision is made along the side of the nose to access the bone. The lacrimal sac is opened and connected to the nasal mucosa through a new duct opening created in the bone.
• Endonasal endoscopic DCR – This minimally invasive surgery accesses the tear drainage system through the nasal cavity without any external incisions. Small openings are made in the lacrimal bone inside the nose under endoscopic visualization.
• Laser-assisted DCR – Laser energy can be used to precisely create the passageway between the lacrimal sac and nasal cavity with less bleeding risk and damage.
• Balloon catheter dilation – A small balloon is inserted into the tear drainage system via the nasal cavity and inflated to widen the drainage opening. Less invasive alternative.
• Silicone intubation – Silicone tubes may be left stent open the surgically created passages for several weeks after surgery to prevent scarring and closure as healing occurs.
Tear duct surgery is typically recommended for chronic epiphora when 6-12 months of conservative treatment fails to improve drainage. Potential complications include scarring, infection, bleeding, and failure to resolve symptoms. Proper aftercare is crucial.
Preparing for Tear Duct Surgery
Patients will need to take certain steps to prepare for upcoming tear duct surgery. The preoperative process typically involves:
• Medical evaluation – Physical exam and lab tests to ensure the patient is healthy enough for surgery. Past medical issues are reviewed.
• Medication instructions – Directions to stop blood thinners or other drugs that increase bleeding risks before surgery.
• Fasting – No eating or drinking after midnight on the night before surgery. Fasting prevents anesthesia complications.
• Arranging help – Assistance with transportation and homecare is organized, as driving and strenuous activity is restricted after surgery.
• Time off work – Patients will need to take at least 1 week off work while recovering, sometimes longer depending on the job.
• Childcare – If caring for young children, make arrangements for help with childcare duties during the recovery period.
• Eye drop instructions – Antibiotic and anti-inflammatory eye drops may be prescribed to use for 1-2 days pre-op to prevent infection.
Following all preoperative instructions carefully allows patients to enter surgery in optimal health, fully prepared for the procedure and recovery process. Ask any questions ahead of time so you know exactly what to expect before tear duct surgery.
Recovering from Tear Duct Surgery
The initial recovery after tear duct surgery usually involves:
• Overnight hospital stay – Patients are monitored for several hours after surgery before discharge. The operated eye is kept lubricated while awake and patched when sleeping.
• Medications – Oral antibiotics, pain relievers, and corticosteroid eye drops are commonly prescribed for 1-2 weeks post-op.
• Wound care – Incision sites are kept clean and dry. Sutures may need to be removed around 1 week after surgery.
• Nasal care – Saline spray, humidifier use, and proper hygiene prevents crusting and promotes healing inside the nasal cavity.
• Activity restrictions – No heavy lifting, bending, straining, or strenuous activity for at least 1 week. Work/school is missed for 7-14 days.
• Follow up appointment – The surgeon evaluates healing progress and may remove silicone tubes if present about 4-8 weeks after surgery.
• Symptom improvement – Tearing and drainage problems may steadily improve over the first 1-2 months. Complete resolution takes up to 3 months.
Proper aftercare and adherence to all postoperative instructions is crucial for effective healing after tear duct procedures. Patients should notify their surgeon about any concerns, side effects, or complications. Full recovery takes time and patience.
Results and Outcomes of Tear Duct Surgery
When successful, tear duct surgery can provide tremendous relief from chronic epiphora. Reported success rates range from 80-99% depending on the specific surgical approach and individual factors. The surgery aims to bypass the obstructed drainage system and create a new tear drainage pathway into the nose.
Benefits when surgery succeeds:
• Greatly reduced excess tearing and watery eyes
• Relief from constant tearing overflow onto the cheeks
• Improved quality of life without nuisance wetness/stickiness
• Decreased risk of infections due to improved tear drainage
If symptoms persist after the initial surgery, secondary procedures may be done to open the drainage pathway and improve results:
• Silicone tube placement to stent open the drainage opening
• Balloon dacryoplasty to dilate any residual narrowing
• Repeat dacryocystorhinostomy if prior procedure fails
For the small percentage of patients where repeat tear duct surgery fails, alternative options include:
• Ongoing conservative treatments to manage excess tearing
• Prescription anti-inflammatory eye drops
• Plugs to occlude the tear ducts and prevent drainage
• Permanent closure of the tear puncta
With proper technique and aftercare, the vast majority of patients see their annoying epiphora symptoms finally resolve with successful tear duct surgery. This surgery can greatly boost quality of life when obstructed tear drainage causes chronic tearing issues.
Living with a Blocked Tear Duct
For those who opt not to undergo tear duct surgery, there are some methods to help manage annoying epiphora symptoms:
• Warm compresses – Applying a warm washcloth to the inner eye can help stimulate drainage and unblock mild obstructions.
• Nasal hydration – Keeping nasal passages lubricated with saline spray can improve tear drainage through the nose.
• Eyelid massage – Gently massaging the eyelids in downward motion can promote flow through blocked ducts.
• Antibiotic ointment – Applying antibacterial cream helps prevent secondary infections from constant wetness.
• Artificial tears – Lubricating eye drops can provide temporary relief when excess tearing occurs.
• Punctal occlusion – Plugging the tear duct opening with removable devices prevents drainage.
• Medications – Prescription anti-inflammatories and steroids help reduce swelling of blocked ducts.
While conservative measures may help manage symptoms, chronic epiphora is difficult to treat without surgery to unblock the tear drainage system. Tear duct procedures are generally recommended after 6-12 months if other treatments continue to provide inadequate relief.
The keys are keeping the eyes as dry as possible and preventing infections until drainage can be restored. With patience and regular eye care, living with a blocked tear duct is manageable for some patients.
Conclusion
Blocked tear ducts can significantly reduce quality of life when excess tearing becomes a chronic nuisance. Epiphora, or watery eyes overflowing onto the cheeks, is the classic symptom of obstructed tear drainage pathways. While some conservative treatments may provide temporary relief, tear duct surgery offers a more permanent solution by creating a new drainage route for tears to flow into the nose.
Procedures like dacryocystorhinostomy can be highly effective at resolving epiphora when performed properly. With excellent success rates, tear duct surgery allows many patients to finally experience relief from chronic excess tearing issues. By consulting an ophthalmologist, those struggling with blocked tear ducts can explore their options and determine if surgery may be appropriate to restore normal tear drainage and comfort.
