[Inverted papilloma. Review of 23 cases]

Inverted papilloma is a benign sinonasal tumour with a high recurrence rate and its treatment must be surgery, using endonasal surgery or external aproach. We present a retrospective study of 23 cases treated in our center from 1988 to 2003. There were 15 males and 8 females with a mean follow-up of 6 years. The recurrence rate was 40.9%. Patients who underwent endonasal surgery had a recurrence rate of 36.6%, and those who underwent external aproach surgery had a recurrence rate of 45.5%. There was a 4.5% of association with carcinoma. Endonasal surgery might be a valid surgery aproach for the treatement of inverted papilloma in selected cases.
