All cases are advanced in instage. 4. CT findings of mixillary sinus cancer were soft tissue density filling the maxillary antrum, soft tissue dunsity beyond the antrum, low density within the mass, punctate or amorphous calcifications within the mass, antral expansion and irregular bony wall thickeness, maxillary bony wall destruction, lymphadenopathy and distant metastasis. 5. Destruction of surfaces of maxillary bony walls were seen in the nasal surface(20 cases), facial surface(16 cases), intratemporal surface(14 cases) and orbital surface(11 cases). 6. The superioty of CT 개 the conventional sinus radiologic imaging were evident in different are as of tumor evaluation of tumor invasion to the infratemporal fossa, posterior ethmoid sinus, orbital apex, nasopharynx, cribriform plate, sphenoid sinus and skull base. 7.
