Summary

This modified endoscopic dacryocystorhinostomy (DCR) uses a mucosal flap and silicon sheet, avoiding canaliculi manipulation. It offers a safe and effective surgical option for chronic dacryocystitis and nasolacrimal duct stenosis.

Area of Science:

  • Otolaryngology
  • Ophthalmology

Context:

  • Chronic dacryocystitis and nasolacrimal duct stenosis often require dacryocystorhinostomy (DCR).
  • Endoscopic DCR is a common alternative to external approaches.
  • Mucosal preservation is key to preventing complications like granulation tissue.

Purpose:

  • To describe a modified endoscopic dacryocystorhinostomy (DCR) technique.
  • To detail modifications including a mucosal flap and silicon sheet use.
  • To present an alternative to traditional silicon tubing in DCR.

Summary:

  • The modified technique involves creating a large bony opening for lacrimal sac and nasal mucosa anastomosis.
  • A silicon sheet is used instead of tubing to prevent canaliculi manipulation.
  • This approach prioritizes mucosal preservation to minimize ostium complications.

Impact:

  • The modified endoscopic DCR is easy to implement for otolaryngologists skilled in endoscopic sinus surgery.
  • It offers a safe and effective method for treating nasolacrimal duct obstruction.
  • This technique may reduce complications associated with traditional DCR methods.
