Endoscopic DCR

Endoscopic DCR

Definition

Endoscopic Dacryocystorhinostomy (DCR) is a minimally invasive surgical procedure to treat blocked tear ducts. Using an endoscope, a new drainage pathway is created between the tear sac and nasal cavity, restoring normal tear flow.

Purpose of Endoscopic DCR

  • To relieve chronic tearing (epiphora) caused by blocked tear ducts

  • To prevent recurrent eye infections or inflammation

  • To restore proper tear drainage and eye comfort

  • To improve overall ocular health and quality of life

Types and Methods of Endoscopic DCR

Endoscopic (Internal) DCR

  • Performed through the nasal cavity using a small endoscope

  • No external incision, minimal scarring

  • Often combined with placement of a silicone stent for long-term patency

External DCR (Traditional)

  • Incision made on the side of the nose

  • Still used in complex cases or failed endoscopic attempts

Surgical Techniques

  • Local or general anesthesia depending on patient needs

  • Precise removal of bone and tissue to create a new drainage pathway

  • Post-operative care includes nasal irrigation and follow-up

Benefits of Endoscopic DCR

  • Minimally invasive with no visible external scar

  • Relieves chronic tearing and discomfort

  • Reduces risk of recurrent infections

  • Restores proper tear drainage and eye comfort

  • Quick recovery and improved quality of life
