Endoscopic DCR

Endoscopic dacryocystorhinostomy (DCR) is a surgical intervention for epiphora caused by obstruction of the nasolacrimal duct. Understanding endonasal anatomy, wide endoscopic marsupialization of the lacrimal sac, and meticulous care of the nasal mucosa are important to achieve good results.

Patients develop symptoms of tearing when there is an imbalance between tear production and the drainage function of the lacrimal system. Tearing can therefore be caused by

  • Hypersecretion
  • Epiphora
  • Combinations of the above

What is dacryocystorhinostomy?

Dacryocystorhinostomy (DCR) is a surgical procedure performed to treat a blocked tear duct. The tear duct, also known as the nasolacrimal duct, is a small channel that drains tears from the eye into the nose. When this duct becomes blocked or obstructed, tears cannot drain properly, leading to excessive tearing and potential infections.

DCR is commonly performed to alleviate the symptoms associated with a blocked tear duct and improve tear drainage. The procedure involves creating a new channel or bypass between the lacrimal sac (a small pouch that collects tears) and the nasal cavity. This bypass allows tears to flow directly from the lacrimal sac into the nose, bypassing the blocked or narrow portion of the tear duct.

There are two main types of DCR:

1. External DCR: In this approach, a small incision is made on the side of the nose near the tear sac. The surgeon creates a new pathway between the tear sac and the nasal cavity and inserts a stent to keep the pathway open during the healing process. This stent is usually removed after a few weeks.

2. Endoscopic DCR: In this minimally invasive technique, an endoscope is used to visualize the tear duct and surrounding structures through the nasal cavity. The surgeon creates the new channel with specialized instruments, without the need for external incisions. Stents may or may not be used in this method, depending on the surgeon's preference. DCR is generally considered a safe and effective procedure for treating chronic tear duct obstruction. It can significantly improve symptoms such as excessive tearing, recurrent eye infections, and discomfort caused by a blocked tear duct. However, as with any surgical procedure, there are some risks and potential complications that should be discussed with a qualified ophthalmologist or an oculoplastic surgeon before undergoing the surgery.
