Mononostril Endoscopic Approach for Bilateral Sphenoid Sinus Lesions

Abstract

Introduction: A mononostril endoscopic approach was attempted for bilateral sphenoid sinus lesions. The objective of this study was to introduce the surgical method along with treatment results for patients. Methods: We retrospectively analyzed 16 patients who underwent a mononostril endoscopic surgery for bilateral sphenoid lesions from 2018 to 2022. Results: Endoscopic mononostril surgery for bilateral sphenoid lesions was performed for 13 cases under general anesthesia and 3 cases under local anesthesia. The surgical approach to the sphenoid sinus was transnasal approach in 8 cases and transethmoidal in 8 cases. Among those with bilateral sphenoid sinuses lesions, fungal ball and sinusitis were the most common. After surgery, the size of the sphenoid sinus opening remained almost the same in 14 patients. It decreased but maintained in 2 patients. There was no recurrence of sphenoid lesions. Conclusion: The mononostril endoscopic approach for bilateral sphenoid lesions is a feasible, safe, effective, and minimally invasive surgical technique.
