The paranasal sinuses consist of the maxillary, ethmoid, sphenoid, and frontal sinuses (figure 1). Paranasal sinus cancer is rare; in the United States about 2000 people, mainly aged 45 to 85, develop nasal cavity and paranasal sinus cancer annually [1]. Higher rates are seen in Japan and South Africa. The incidence is higher in males than in females (2:1). Lesions of the maxillary sinus are most common, followed by the ethmoid, sphenoid, and frontal sinuses.
