[EN]Introduction: To evaluate clinical outcomes of external versus endoscopic approaches in the treatment of sinonasal inverted papilloma (IP). Methods: A retrospective analysis was conducted on 50 patients treated between 1995 and 2018. Patients were categorized by surgical approach, external or endoscopic, and evaluated for demographics, risk factors, complications, recurrence, and disease-free survival. Statistical analysis included Kaplan–Meier survival curves and bivariate tests. Results: The external group showed a lower recurrence rate (22.7%) compared to the endoscopic group (35.7%), although the difference was not statistically significant (p = 0.279). However, the endoscopic group required more reinterventions (p = 0.029). Five-year disease-free survival was comparable (52.4 months vs. 48.9 months; p = 0.60). Aesthetic outcomes favored endoscopy (p < 0.001). Neoplastic transformation occurred in 8% of cases, with no significant difference between groups. Conclusion: Both approaches offer effective long-term outcomes, but recurrence appears to be more closely associated with tumor extension than with surgical technique. These findings underscore the importance of individualized surgical planning and long-term follow-up, particularly in advanced-stage cases.
