Tumors of the naso-sinus cavities are rare, they are characterized by a pathological variety. The surgical procedures are influenced by preoperative knowledge of the nature and topography of the tumor. Imaging, combining CT and MRI, plays an important role in the preoperative evaluation of naso-sinus tumors. Objectives: The aim of this work is to describe the epidemiology of sino-nasal tumors, to identify the clinical and radiological variables may predict malignancy, and to correlate radiographic and pathological results. Materials and methods: A retrospective study spread over four years from 1 April 2007 to 1 April 2011. We selected all patients operated for sino-nasal tumors, excluding the maxillary odontogenic cysts and inflammatory diseases: polyps. We analyzed clinical and radiologic images in CT and MRI preoperatively, and compared with pathological findings. Results: The results were analyzed using the Khi 2 test. Benign tumors were predominant with 65.5%. Squamous cell carcinoma was the most represented malignancy (44%). No sex difference was observed for two types of tumors. The mean age for benign tumors was 35.5 years and 47 years for malignant tumors. The epistaxis, facial pain and facial swelling were significantly associated with malignancy. The scanner, bone lysis, the irregular boundaries of the mass, and enhancing the PDC were significantly predictive of malignancy. 19 benign tumors were falsely interpreted by the scanner: 7 as malignant tumors and 12 as a polyp. CT was able to diagnose all malignant tumors. MRI performed in only 10 patients with malignant tumor confirmed the diagnosis. Conclusion: The accurate assessment of preoperative nasal sinus tumors has become a real challenge for ENT and radiologists. imaging data are needed to approach a correct diagnosis, however, histology remains obligatory.
