Management of Maxillary Sinus Inverted Papilloma Using Endoscopic Modified Medial Maxillectomy (EMMM) and Direct...

Inverted papilloma is a benign sinonasal tumor characterized by local aggressiveness, a high recurrence rate, and potential malignant transformation. This report presents a case of inverted papilloma originating in the maxillary sinus, successfully treated using a fully endoscopic surgical approach with en bloc resection. This case demonstrates the safety and efficacy of endoscopic techniques for managing maxillary sinus inverted papilloma while preserving the nasolacrimal duct; it also highlights the importance of meticulous surgical planning, intraoperative precision, and long-term follow-up to optimize outcomes and reduce recurrence risk. Postoperative recovery was uneventful, and the 12-month follow-up demonstrated no evidence of recurrence or complications.
