Aims Despite improvements in surgical techniques and equipment, sinonasal inverted papilloma (IP) continues to demonstrate high rates of recurrence, reminding surgeons that mastery of anatomy alone is not the full answer. This presentation revisits IP through the lens of modern endoscopic surgery, exploring how anatomy, technology, and evolving biological understanding converge to shape outcomes in 2025. Methodology A synthesis of recent systematic reviews, multicentre series, and translational studies was performed to examine progress across key domains: epidemiology, diagnostic imaging, endoscopic technique, and evolving risk factors for recurrence. Results IPs remain the most common benign sinonasal tumours, with recurrence rates that persist even in expert hands. High-resolution CT and MRI provide precise mapping of tumour extent, while radiomic imaging models are beginning to identify subtle features linked to attachment site and malignant potential. Contemporary endoscopic approaches have shifted from radical resections toward attachment-oriented, anatomy-preserving surgery, improving access and function while maintaining oncologic safety. Multi-institutional data highlight that disease in the frontal sinus and lateral maxillary wall still carries the highest risk of recurrence In these areas, complete clearance can be technically challenging. Novel adjunctive topical therapies, such as 5-fluorouracil, are being explored for difficult or recurrent disease, though current evidence remains preliminary. Long-term follow-up remains indispensable. Conclusion Inverted papilloma remains one of rhinology’s most humbling diseases. It is technically conquerable yet biologically unpredictable. The next step for surgeons lies not in wider exposure but in smarter prediction: combining meticulous endoscopic technique, refined imaging, and selective biological insight to anticipate who will recur and why.
