About Dacryocystorhinostomy
Dacryocystorhinostomy (DCR) is a surgical procedure designed to treat nasolacrimal duct obstruction, which often results in chronic dacryocystitis and excessive tearing (epiphora). The lacrimal system, responsible for tear production and drainage, can become blocked due to various reasons such as congenital anomalies, infections, inflammation, trauma, or neoplasms.
What is a Dacryocystorhinostomy?
Dacryocystorhinostomy (DCR) is a surgical procedure aimed at treating blocked tear ducts. It creates a new pathway for tears to drain directly into the nasal cavity, bypassing the obstruction and alleviating symptoms like excessive tearing and recurrent infections. The nasolacrimal duct is responsible for draining tears from the lacrimal sac into the nasal cavity. When this duct becomes blocked, it can cause tears to overflow onto the face and lead to recurrent infections. There are two main types of DCR: external and endoscopic.
External DCR involves making an incision on the side of the nose to access the lacrimal sac and create a new opening into the nasal cavity. This method has been traditionally used and is known for its high success rate.
Endoscopic DCR, on the other hand, is a minimally invasive technique performed through the nasal passage using an endoscope. This approach avoids external scarring and has become increasingly popular due to advancements in endoscopic technology.
Patients who undergo DCR typically present with symptoms such as excessive tearing, recurrent eye infections, and mucous discharge. The diagnosis of nasolacrimal duct obstruction is confirmed through clinical examination and imaging studies, such as dacryocystography or lacrimal scintigraphy. These tests help determine the location and extent of the blockage, guiding the surgical approach.
The procedure itself involves several steps. In external DCR, after making the incision, the surgeon removes a small piece of bone to create a direct connection between the lacrimal sac and the nasal cavity. A silicone tube is often inserted to keep the new passage open during the healing process. In endoscopic DCR, the surgeon uses specialized instruments to create the new drainage pathway through the nasal passage, also often placing a stent to maintain patency.
Symptoms of a Blocked Tear Duct
A blocked tear duct, also known as nasolacrimal duct obstruction, can cause a variety of symptoms that affect the eyes and surrounding areas.
One of the most common symptoms is excessive tearing or watery eyes, medically referred to as epiphora. This occurs because the tears cannot drain properly through the tear duct system, leading to an overflow of tears onto the face.
Another noticeable symptom is redness and irritation of the affected eye. This can be accompanied by painful swelling near the inside corner of the eye, where the tear duct is located. The blockage can also lead to recurrent eye infections or inflammation, such as conjunctivitis or pink eye, which can cause further discomfort and redness.
Patients with a blocked tear duct often experience crusting of the eyelids and mucus or pus discharge from the eye. This discharge can accumulate on the eyelids and lashes, especially after sleeping, leading to a sticky or crusty buildup. The presence of mucus or pus indicates that the tear duct blockage may be complicated by an infection, which requires medical attention.
Blurred vision is another symptom that can occur due to excessive tearing and discharge. The constant presence of tears and mucus on the surface of the eye can interfere with clear vision, making it difficult to see properly. Additionally, the irritation and inflammation caused by the blockage can contribute to visual disturbances.
In some cases, a blocked tear duct can cause a painful lump or swelling near the inner corner of the eye. This lump, known as a dacryocystocele, forms when the tear sac becomes swollen and infected due to the trapped tears. The area around the lump may be tender to the touch and can become more painful if the infection worsens.
Causes of a Blocked Tear Duct
A blocked tear duct, or nasolacrimal duct obstruction, can occur due to various causes, affecting individuals of all ages.
One of the primary causes is congenital blockage, which is common in newborns. In these cases, the tear drainage system may not be fully developed, or there may be a thin tissue membrane covering the opening of the nasolacrimal duct. This condition often resolves on its own within the first year of life.
Age-related changes are another significant cause. As people age, the tiny openings that drain tears, known as puncta, can become narrower, leading to blockages. This narrowing can impede the normal flow of tears, causing them to back up and overflow onto the face.
Infections and inflammations are also common culprits. Chronic infections or inflammations of the eyes, tear drainage system, or nasal passages can lead to scarring and blockages in the tear ducts. Conditions such as conjunctivitis or sinusitis can contribute to this problem, as the inflammation can spread to the tear ducts.
Injury or trauma to the face can cause blockages as well. Any damage to the bones or tissues around the tear drainage system can result in scarring or structural changes that obstruct the flow of tears. Even minor injuries, such as getting dirt or small particles in the eye, can lead to temporary blockages.
Tumors are a less common but serious cause of blocked tear ducts. Tumors in the nasal passages or along the tear drainage system can press on the ducts, causing obstruction. Early detection and treatment of such tumors are crucial to prevent further complications.
Certain medical treatments can also lead to blocked tear ducts. Long-term use of eye drops for conditions like glaucoma, as well as cancer treatments such as chemotherapy and radiation, can cause changes in the tear drainage system that result in blockages.
In some cases, systemic diseases like sarcoidosis or Wegener's granulomatosis can infiltrate the tear ducts, leading to obstruction. These diseases cause inflammation and granuloma formation, which can block the tear ducts.

The risks of a Dacryocystorhinostomy
Dacryocystorhinostomy (DCR) is a surgical procedure designed to treat blocked tear ducts, which can cause excessive tearing and recurrent eye infections. While DCR is generally considered safe and effective, it does come with several risks and potential complications that patients should be aware of before undergoing the procedure.
One of the primary risks associated with DCR is infection. As with any surgical procedure, there is a possibility of infection at the surgical site, which can lead to further complications if not promptly treated. Patients are typically prescribed antibiotics to mitigate this risk, but it remains a concern.
Another significant risk is excessive bleeding during or after the surgery. This can be particularly problematic for patients with underlying health conditions that affect blood clotting.
Scarring is another potential complication, especially with the external approach to DCR, where an incision is made on the skin. This can result in a prominent facial scar, which may be a cosmetic concern for some patients.
Additionally, there is a risk of the stent or tube, which is often placed to keep the new tear duct open, becoming displaced. If this occurs, it may necessitate further surgical intervention to correct the issue.
Abnormal tissue growth, or synechiae, within the nasal cavity is another risk. This occurs when tissues fuse together abnormally, potentially obstructing the newly created tear duct pathway and requiring additional treatment.
Furthermore, patients may experience persistent tearing or failure of the surgery to resolve the initial problem, necessitating repeat procedures.
Older adults undergoing DCR may face increased risks of serious complications. Studies have shown that the likelihood of adverse outcomes, such as infection and excessive bleeding, is higher in older patients. This demographic may also have other comorbidities that complicate the surgical process and recovery.
During a dacryocystorhinostomy
Dacryocystorhinostomy (DCR) is a surgical procedure aimed at creating a new tear drainage pathway between the lacrimal sac and the nasal cavity to bypass a blocked nasolacrimal duct. The surgery steps include:
The surgery can be performed using either an external or endoscopic approach. In the external approach, the surgeon makes a small incision on the side of the nose, just below the eye. This allows direct access to the lacrimal sac and the bone that separates it from the nasal cavity. In the endoscopic approach, no external incision is made; instead, the surgeon uses a thin, flexible tube with a camera (endoscope) inserted through the nostril to visualize and access the surgical site.
Once access is gained, the surgeon removes a small piece of bone to create an opening between the lacrimal sac and the nasal cavity. This new passageway allows tears to drain directly into the nose, bypassing the blocked duct. The surgeon then creates an opening in the lacrimal sac and the nasal mucosa, ensuring that the new pathway remains open.
To keep the new tear duct, open during the healing process, a small silicone tube or stent is often placed through the new passageway. This stent helps maintain the opening and prevents scar tissue from closing it off. The stent is usually left in place for several weeks to months and is removed during a follow-up visit.
Throughout the procedure, the patient is typically under local anesthesia with sedation or general anesthesia, depending on the specific case and patient preference. Local anesthesia numbs the surgical area, while sedation helps the patient relax. General anesthesia renders the patient unconscious, ensuring they feel no pain during the surgery.
After the procedure, the surgical site is carefully closed if an external incision was made. The patient is then monitored in a recovery area until the effects of anesthesia wear off. Post-operative care includes the use of antibiotic eye drops or ointments to prevent infection and nasal sprays to keep the nasal passages clear. Patients are advised to avoid activities that could increase nasal pressure, such as blowing their nose or heavy lifting, for a few weeks.
Follow-up visits are crucial to monitor the healing process and ensure the new tear drainage pathway remains open. The surgeon will check the position of the stent and remove it once the area has healed sufficiently.
Blocked Tear Duct Surgery Recovery
Recovery from blocked tear duct surgery, specifically dacryocystorhinostomy (DCR), involves several stages and requires careful post-operative care to ensure successful healing and the restoration of normal tear drainage.
Immediately after the surgery, patients are usually monitored in a recovery area until the effects of anesthesia wear off. Depending on whether the procedure was performed externally or endoscopically, there might be some initial discomfort, swelling, and bruising around the surgical site. Pain is generally mild and can be managed with over-the-counter pain relievers as recommended by your surgeon.
In the first few days’ post-surgery, it’s common to experience some blood-stained nasal discharge, especially if the endoscopic approach was used. Patients are advised to avoid activities that could increase nasal pressure, such as blowing their nose, sneezing forcefully, or heavy lifting, to prevent disrupting the surgical site. Using a nasal decongestant spray and prescribed antibiotic eye drops or ointments can help reduce inflammation and prevent infection.
A small silicone stent or tube is often placed during the surgery to keep the new tear duct pathway open. This stent typically remains in place for several weeks to months and is removed during a follow-up visit. During this period, patients might notice some residual tearing, which usually diminishes as the area heals.
Regular follow-up appointments are crucial to monitor the healing process and ensure the new tear drainage pathway remains open. Your surgeon will check the position of the stent and remove it once the area has healed sufficiently. Most patients can resume normal activities within one to two weeks, although complete healing and the resolution of all symptoms may take a bit longer.
In terms of lifestyle adjustments, patients are advised to keep the surgical area clean and dry, avoid rubbing their eyes, and follow any specific instructions given by their healthcare provider. It’s also important to watch for signs of complications, such as increased pain, redness, swelling, or discharge, and report these to your doctor promptly.
Overall, while the recovery process from blocked tear duct surgery requires some patience and care, most patients experience significant relief from their symptoms and improved tear drainage.
