To the best of our knowledge, this is the largest series reported to date of malignant tumors of the sinonasal tract and adjacent skull base treated with pure endoscopic or cranioendoscopic techniques. A 5-year disease-specific survival of 91.4% and 58.8% for the EEA and the CEA groups, respectively, seem to indicate that endoscopic surgery, when properly planned and in expert hands, may be a valid alternative to standard surgical approaches for the management of malignancies of the sinonasal tract.

Endoscopic surgery is a safe and effective treatment for paranasal sinuses FB. A proper imaging study by MR and/or CT can address diagnosis, which is based upon detection of fungal hyphae at histology.

Background. The purpose of this study was to define the optimal surgical strategy for sinonasal inverted papilloma in relation to the site of origin and tumor extent.Methods. Retrospective analysis of patients affected by inverted papilloma treated by purely endoscopic or combined approaches at the Department of Otorhinolaryngology of the University of Brescia and Pavia-Varese from November 1991 to December 2007.Results. Two hundred twelve patients were considered eligible for this study. An exclusive endoscopic approach was performed in 198 patients (93.4%); the remaining 14 patients (6.6%) underwent an endoscopic approach combined with an osteoplastic frontal flap. Follow-up ranged from 24 to 192 months (mean, 53.8 months). A single recurrence was observed in 12 patients (5.7%). Twenty complications (9.4%) were observed.Conclusion. Endoscopic surgery is the first choice in the treatment of inverted papilloma; only lesions with extensive involvement of frontal sinus and/or supraorbital cell may require a combined approach. A minimum follow-up of 5 years is recommended.
