Endoscopic Resection of Inverted Papilloma in the Maxillary Sinus - ‘Prelacrimal Approach,’ ‘Origin Site Cauterization and Drilling (Painting and Washing)’

Inverted papilloma is a common, benign sinonasal tumor with a known high rate of recurrence. To prevent recurrences, complete excision of inverted papilloma is essential. In complete excision, especially, identifying the attachment site of the tumor and managing the site meticulously is important. In this study, we introduce two surgical methods for complete excision of inverted papilloma that can reduce the recurrence rate: the prelacrimal approach and the ‘origin site cauterization and drilling (painting and washing)’ approach.
