Introduction and objective:

Nasosinusal inverted papilloma is a benign epithelial tumor that has a locally aggressive behavior which requires surgical treatment by functional endoscopic sinus surgery (FESS) and long-term follow-up due to the risk of recurrence-persistence. Our objective is to evaluate the efficacy of surgical treatment of inverted papilloma, as well as the incidence of recurrence of the disease after surgery.

Method:

A retrospective study of 39 patients treated for inverted papilloma between 2006 and 2020 was carried out, recording demographic data tumor characteristics, as well as analyzing the incidence of persistence (before 6 months) or recurrence (after 6 months) after surgical treatment.

Results:

82% of the cases were men with a mean age of 54 years. The most frequent location was the lateral nasal wall, 38,5%. 89,7% (35/39) of the cases diagnosed with inverted papilloma were treated surgically using FESS, obtaining a percentage of persistence and recurrence of 2,6%. 7,7% (3/39), being lesions of the nasal vestibule, were simply resected. In one specific case (2,6%), it was necessary to perform frontal osteoplasty due to extension of the papilloma. No atypia nor malignancy were found in any of the cases.

Discussion and conclusions:

The gold standard in the surgical treatment of inverted papilloma is FESS, considering medial maxillectomy in most cases. Surgical treatment of IP using this technique has a low rate of persistence and recurrence.
