Paranasal sinus cancer are rare entities, but when diagnosed, often already in advanced stages of the disease, because the neoplastic process in the initial stages grows invading the paranasal sinuses and then in advanced stages, produces deformation of cortical bone. Among the clinical manifestations epistaxis, nasal obstruction, pain in maxillary area, pain or tooth mobility may occur. We present two clinical cases in which within the first manifestations are the maxillary pain and abnormal tooth mobility. When making the final diagnosis, tumor processes were well advanced, engaging various structures as maxillary sinus, ethmoid, sphenoid, and orbital floor, forcing large resections perform maxillofacial area. The role of the dentist in the diagnosis of the disease could be of great importance, suspecting that an increase maxillary volume, abnormal tooth mobility or pain of the maxillary not always correspond with odontogenic causes.
KEY WORDS: paranasal sinus cancer, sinonasal carcinoma, malignant neoplasms.
