Tumores benignos nasosinusais: Estudo retrospectivo Benign nasosinusal tumors: Restrospective study

Objectives: Benign sinonasal tumors (BST) are rare and usually asymptomatic. When symptomatic or withpending complications the surgical treatment, with endonasal and/ or external approaches, is recommended. The purpose of this study was to evaluate the recent experience of the Hospital S. Joao in the surgical treatment of BST. Study Design: Retrospective study Material and Methods: Evaluation of cases of BST treated surgically between 2005 and 2009 Results: The most common tumor was inverted papillomas (63%). The mean age at presentation was 52 years with male predominance (68%). About 50% of tumors were located in the lateral nasal wall. The endonasal surgical approach was used in 84% of cases and combined approach (endonasal and external) in 3 (16%). There was recurrence in two cases of inverted papilloma and another showed malignancy. Conclusions: BST are frequent indication for surgery. Currently, the approach of choice is endonasal. However, the external approach is still vital in certain situations.
