【摘要】OBJECTIVE To explore and evaluate the value of CT in diagnosis of malignant tumor of maxillary sinus and the accuracy of the involved bone wall by comparing the preoperative CT imaging with the pathologic examination.METHODS 11 patients without maxillary sinus squamous cell carcinoma and lymph node metastasis received pathological examination and enhanced CT scan before operation, partial or total maxillary resection were implemented according to the CT features and scope. The position and azimuth of the cut bone tissue samples were marked. The specimens were routinely fixed, decalcified, embedded, sliced and HE stained to observe the bone tissue pathological changes on the bone wall under light microscope.RESULTS Nasal sinus enhancement CT scan showed that the medial wall of maxillary sinus were all resorped and invaded(4 cases lack inner wall). Anterior wall was invaded in 6 cases, superior wall in 7 cases and bottom wall in 3 cases, posterior and exterior wall in 9 cases; After ruling out the cases without internal wall of maxillary sinus, the inner wall of the maxillary sinus was invaded by cancer cells, so was the front
