Endoscopic intranasal dacryocystorhinostomy offers a minimally invasive surgical option for nasolacrimal duct obstruction. This technique achieves success rates comparable to traditional external approaches, improving patient outcomes.

Area of Science:

  • Otolaryngology
  • Ophthalmology
  • Minimally Invasive Surgery

Background:

  • Traditional dacryocystorhinostomy often requires an external approach due to limited intranasal visualization.
  • The nasolacrimal apparatus is anatomically situated near the lateral nasal wall, suggesting potential for endoscopic access.
  • External approaches can cause cosmetic concerns and may interfere with the lacrimal pump mechanism.

Purpose of the Study:

  • To describe an endoscopic intranasal dacryocystorhinostomy technique.
  • To evaluate the efficacy and success rates of this minimally invasive approach.
  • To compare endoscopic outcomes with conventional external dacryocystorhinostomy.

Main Methods:

  • Detailed description of the endoscopic intranasal surgical procedure.

  • Intranasal visualization and instrumentation for accessing the nasolacrimal sac and duct.
  • Minimizing functional interference with the lacrimal pump during surgery.

    • Main Results:

    • Successful endoscopic intranasal dacryocystorhinostomy reported.
    • Achieved success rates comparable to the conventional external approach.
    • Demonstrated preservation of physiological lacrimal pump function.

    Conclusions:

    • Endoscopic intranasal dacryocystorhinostomy is a viable and effective surgical technique.
    • This approach provides comparable outcomes to external methods with potential benefits.
    • Minimally invasive endoscopic surgery revolutionizes nasal and sinus disorder management.
