The detectability of bone destruction is discussed and a comparison is presented of Caldwell's and Waters' views, maxillary tomography and CT scans of 10 patients with maxillary cancer. Destruction of the lateral wall of the maxillary sinus was confirmed in all 10 patients by CT scan, but destruction of the tuber maxillary line (T-M line) could not be seen in Caldwell's and Waters' views in 5 of the patients. As a rule, frontal tomography was helpful in the observation of the orbital base, the median wall of the maxillary sinus and the nasal cavity. However, CT scan was the best method, and accurate with observation of the anterior wall of the maxillary sinus was possible only with axial CT.
