Tearing is most commonly due to a blockage or narrowing of the nasolacrimal duct. The nasolacrimal duct tends to narrow with age, but this process is probably exacerbated by persistent infections and can occur earlier in life (see Tearing in Children). In order to cure tearing caused by nasolacrimal duct narrowing or obstruction a dacryocystorhinostomy (DCR) is required.
During DCR surgery a new connection between the lacrimal sac ("tear sac") to the inside of the nose is made. This by-passes the narrowed or obstructed duct along which the tears normally pass from the tear sac into the nose. A fine silicon stent (tube) is often placed during the surgery to maintain the opening in the tear system during the healing process. Tube removal is 2 - 4 weeks postoperatively in the rooms and is completely painless.
With advances in technology and instrumentation over the past 15 years it has become possible to perform DCR surgery through the nostril with no incision on the skin of the face. There are only a handful of surgeons in Australia routinely performing this minimally invasive procedure.
Endoscopic DCR surgery is a day surgery procedure often performed under a general anaesthetic.
Who is suitable for DCR surgery?
What does the treatment involve?
During DCR (dacryocystorhinostomy) surgery a direct opening is created between the tear sac and the nose, bypassing the blocked nasolacrimal duct. The procedure is either performed via a small skin incision on the sidewall of the nose, an "External DCR", or trans-nasally, an "Endoscopic DCR." Both procedures are routinely performed in a day surgery on an outpatient basis.
Endoscopic DCR is routinely performed under general anaesthesia. The operative time for both techniques is approximately 45 minutes.
At the time of surgery a fine silicone stent is placed and then removed 3 weeks post-op in the rooms. Occasionally this prolapses spontaneously requiring an extra visit to the rooms for early removal.
How will I look immediately after surgery?
What is the recovery time?
Post-operative pain is minimal usually requiring no more than Paracetamol, with the main inconvenience being the avoidance of exercise, straining or other activities that increase nasal blood flow and thus the risk of bleeding for the first week.
Your nose will feel congested and some patients will have 1-2days of discomfort in the region of the tear sac. A regime of eye drops and nasal sprays are required post-operatively.
What are the risks?
How long do the results of the surgery last?
The success rate for endoscopic and external DCR is approximately 95%, however tear drainage is a very complex physiological process and tearing may be the result of a number of separate issues. Therefore careful patient selection is essential.
Patients have follow-up for three months to ensure that the new tear pathway matures well. After this period it is very unlikely for the tearing to recu
