INTRODUCTION: Sinonasal Papilloma is a benign tumor originating from the epithelium schneiderian lateral nasal wall. Its incidence is rare and according to literature accounts for 0.5 to 4% of all nasal tumors. OBJECTIVE: To report our institution's experience in the treatment of sinonasal inverted papilloma using endoscopic approach and compare the results with the literature. METHODS: A retrospective study of all patients with sinonasal papillomas who underwent a purely endoscopic surgery in the Otorhinolaryngology, Hospital das Clinicas, Federal University of Bahia (UFBA), from January 2004 to May 2010. RESULTS: A total of 12 patients were included in this study. The median follow-up was 23 months. There was one case of recurrence. Malignant transformation has not occurred in these cases. CONCLUSION: The treatment of sinonasal papilloma has been largely benefited from the advances in endoscopic techniques, with recurrence rates equivalent to those reported for external access. Imaging exams are essential in preoperative planning and the decision of surgical technique. A regular follow-up and long term is essential for a good monitoring of the evolution of this pathology.
