Endoscopic DCR (Dacryocystorhinostomy)

Endoscopic Dacryocystorhinostomy (Endoscopic DCR) is a minimally invasive surgical procedure used to treat blocked tear ducts (nasolacrimal duct obstruction). The surgery creates a new passage between the tear sac and the nasal cavity, allowing tears to drain normally and relieving symptoms such as constant watering, discharge, or infection of the eye. Unlike conventional DCR, the endoscopic approach is performed through the nasal cavity — leaving no external scars and ensuring quicker recovery.

Symptoms

Patients with tear duct obstruction who may benefit from Endoscopic DCR typically experience:

  • Persistent watery eyes (epiphora)
  • Recurrent eye infections or discharge
  • Pain, redness, or swelling near the inner corner of the eye
  • Mucus or pus discharge from the tear duct
  • Blurred vision due to excess tearing
  • Swelling or infection of the lacrimal sac (dacryocystitis)

Causes

Blocked tear ducts may result from a variety of conditions, including:

  • Chronic sinus or nasal infections
  • Previous eye or nasal surgeries
  • Age-related narrowing of the tear duct
  • Trauma or injury to the nose or face
  • Inflammatory disorders affecting the nasal passages
  • Congenital tear duct blockage (common in children)

Treatment / Procedure

Endoscopic DCR is performed under local or general anesthesia using an advanced nasal endoscope. Through the nasal cavity, the surgeon removes a small portion of bone between the nasal passage and the tear sac to create a direct drainage channel for tears. A silicone stent or tube may be placed temporarily to maintain the passage and prevent blockage during healing. The procedure is scarless, bloodless, and usually takes about 30–45 minutes. Most patients can go home the same day.

Benefits

  • No external incision or facial scar
  • Quick and minimally invasive procedure
  • Restores natural tear drainage
  • Reduces tearing, infection, and discomfort
  • Shorter recovery time compared to external DCR
  • Improved cosmetic and functional outcome

Prevention / Post-Surgery Care

While tear duct obstruction cannot always be prevented, proper care after Endoscopic DCR ensures smooth healing and long-term results:

  • Avoid blowing your nose forcefully for at least a week
  • Use prescribed nasal drops and antibiotics as directed
  • Keep the nasal passages clean and free from crusting
  • Avoid exposure to dust, smoke, or infections during recovery
  • Attend regular follow-up appointments to check healing and stent position
  • Report any excessive bleeding, discharge, or swelling to your doctor immediately
