Area of Science:

  • Otolaryngology
  • Rhinology
  • Surgical Innovation

Background:

  • Intranasal sphenoethmoidectomy historically addressed acute bacterial sinusitis.
  • The prevalence of chronic hyperplastic rhinosinusitis now drives ethmoidectomy indications.
  • Effective disease removal is critical for long-term sinus drainage and ventilation.

Purpose of the Study:

  • To present modifications of the Yankauer sphenoethmoidectomy technique.
  • To achieve complete marsupialization of the sphenoid, ethmoid, and maxillary sinuses.
  • To enhance sinus surgeon's ability to clear disease and ensure optimal drainage.

Main Methods:

  • Complete middle turbinate resection.
  • Extended middle meatal antrostomy with palatine bone resection to the pterygoid process.

    • Main Results:

    • Successful application in nearly 2000 procedures.
    • Demonstrated clearance of disease in all treated sinuses.
    • Provided excellent long-term drainage and ventilation.

    Conclusions:

    • Modified Yankauer sphenoethmoidectomy offers a comprehensive approach to chronic rhinosinusitis.
    • Technique modifications facilitate complete disease eradication and sinus marsupialization.
    • Endoscopic assistance enhances surgical precision and accessibility.
