Introduction: Benign sinonasal tumors(BST) are rare and usually asymptomatic. They comprise an hystopatological heterogeneous group of neoplasms that can be classified as follows: fibro-osseous, neurogenic, vascular, epithelial and odontogenic. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) are essential in assessing the location and extent of the lesion, differential diagnosis and surgical planning. Surgical treatment is indicated in symptomatic cases, if there are complications or suspected / malignancy potencial. Minimally invasive endonasal techniques have been replacing the classical external approaches (transfacial or craniofacial).
Objective: Evaluation of cases of BST treated surgically
Methods: Retrospective study (period: last 10 years)
Results: We studied a total of 32 patients. The most frequent tumor was papilloma(56%), followed by osteomas (25%). The mean age at diagnosis was 52 years with a male predominance (60%). Nasal obstruction was the most common presenting symptom. The endonasal surgical approach was used in 87% and was the most frequent. There was recurrence in 7 cases: 6 cases of papilloma and 1 case of osteoma. Features of each of BST included in this series are described and the results. Conclusion: The BST, although uncommon in routine ENT, may be the cause of considerable morbidity. The surgery is an option in particular cases. The philosophy of treatment should follow a balanced algorithm between the need for resection and adverse effects related to the surgical removal.
