What is a dacryocystorhinostomy?
The dacryocystorhinostomy or “DCR” is surgery that enables us to open up an alternative drainage duct to the tear duct. When this duct connecting the eye and the nose is blocked, tears cannot run freely and must be redirected by opening a new way to prevent them from accumulating.
To do so, a small “window” is created in the lachrymal bone, and the lachrymal sac (which collects tears flowing from the eye’s surface and pumps them) with the nasal cavity. The most common way of doing this is through a very discreet micro-insertion in the skin (external dacryocystorhinostomy), although the Miranza specialists are forerunners in Spain and Europe in performing the surgery through the nose, using a small camera (endoscopic or endonasal dacryocystorhinostomy). This avoids any visible mark, reduces the time of the surgery, and speeds up recovery.
Our oculoplastic ophthalmologists were also trailblazers in this surgical intervention in outpatients, and with local anaesthetic and sedation instead of general anaesthetic in most cases. Performed by experts, DCR has a very high success rate of around 90-95%.
Eye diseases treated by dacryocystorhinostomy
Treating blocked tear ducts provides an effective solution to the problem of watery eyes . The dacryocystorhinostomy is especially recommended in patients with very intense excessive tearing and/or repeat infection in the lachrymal sac due to the accumulation of tears.
