[Inverted papilloma: treatment and evolution]

Inverted Papilloma is a frequent bening nasosinusal tumour. The high frequency of recurrences and the malignant potential are its clinical characteristics. We present our experience in a retrospective study done in the last 10 years. 10 patients with Inverted Papilloma have been treated during that period. According to the Classification made by krouse who divides the Inverted Papilloma in four stages, we found 3 in stage I, 6 in stage II and 1 in stage IV. The treatment in almost all of the patients in Stage I and II was endonasal surgery. External approach was performed for stage IV. The recurrence rate was 30% and malignization occurred in 10% of the cases. Finally, we have compared other publications, and revised the literature.
