Surgical Strategy of Inverted Papilloma Originating from Paranasal Sinuses

Advancements in endoscopic techniques and the development of sophisticated surgical equipment, such as navigation systems, have prompted a gradual transition from external to endoscopic approaches in the surgical management of inverted papilloma (IP). The standard treatment for IP involving the paranasal sinuses entails complete tumor resection, with particular emphasis on the complete excision of the tumor attachment or primary site. While preoperative radiological imaging, including computed tomography and magnetic resonance imaging, offers insight into tumor attachment, its accuracy may be limited. Only intraoperative endoscopic findings can definitively ascertain the precise location of tumor attachment within the sinonasal cavity. The surgical strategy for managing IP necessitates a tailored approach contingent upon the tumor
