Summary
Modified intranasal sphenoethmoidectomy techniques improve drainage for chronic rhinosinusitis. This approach ensures complete disease removal and long-term sinus ventilation, enhancing surgical outcomes.
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.
- Delineation of inferior and medial orbital walls.
- Use of operative endoscopes for improved visualization.
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.
