Endonasal dacryocystorhinostomy effectively treats nasolacrimal duct stenosis without external scars. This minimally invasive technique preserves orbital structures and offers excellent binocular vision for surgeons.

Area of Science:

  • Otolaryngology
  • Ophthalmology
  • Surgical Anatomy

Background:

  • Chronic nasolacrimal duct stenosis causes significant symptoms.
  • Traditional surgical approaches may leave external scars or pose risks to orbital structures.

Purpose of the Study:

  • To describe an endonasal dacryocystorhinostomy technique.
  • To evaluate its efficacy in treating nasolacrimal duct stenosis.

Main Methods:

  • Surgical technique using frontal loupe and operating microscope for enhanced visualization.
  • Pre-operative investigations including dacryocystography, CT of paranasal sinuses, and nasal endoscopy.
  • Procedure performed on 12 surgical cases.

Main Results:

  • Successful removal of symptoms related to chronic nasolacrimal duct stenosis.
  • Absence of external scarring.
  • No reported risk to orbital structures.

    • Conclusions:

    • Endonasal dacryocystorhinostomy is a safe and effective surgical approach.
    • The technique allows for free surgeon's hands while maintaining binocular vision.
    • Comprehensive pre-operative assessment is crucial for optimal outcomes.
