SANTAMARIA C, Alfredo et al. Endoscopic management of sinonasal inverted papilloma: 15 years experience in Concepción Clinical Hospital. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2016, vol.76, n.2, pp.155-159. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162016000200002.

Introduction: The inverted papilloma is one of the most common benign tumors of the sinonasal region. The main problems in their management are the recurrence and malignant transformation. Their treatment is surgical removal. Aim: To describe and analyze the clinical and epidemiological characteristics, as well as the results of endoscopic treatment in a tertiary hospital. Materials and methods: A retrospective, descriptive study of all patients with diagnosis ofsinonasal inverted papilloma operated by endoscopic approach between 1997 and 2012 was carried out. Epidemiological and clinical variables were analyzed, including analysis of recurrences and transformation to / association with cancer. Results: 57 cases of sinonasal inverted papilloma were found, 55 of which were endoscopically resected, 65.5% male, 54.7 years old on average. Nasal obstruction was the main symptom. Most of them were in Krouse stage 2 (47.3%) and 3 (32.7%); 7.8% of major complications, which were resolved without sequels. The follow up average was 4.11 years, with a recurrence of 5 (9.1%) cases, and (1.8%) persistence. Association with squamous-cell carcinoma was found in 5.5% of cases. Conclusion: The clinical and epidemiological characteristics do not differ greatly from those reported in the literature. Experience with endoscopic resection in sinonasal inverted papilloma has proven effective in our clinical practice, with a low rate of complications and recurrences, this approach currently being the first choice in most cases.
