Purpose: To investigate the diagnostic value of 16 slices spiral CT in maxillary sinus diseases.
Methods: 16 slices spiral CT findings of 58 cases with maxillary sinus diseases confirmed clinically were analyzed, postprocessing of images was performed by using the software package at the workstation. All the cases were proved by surgery.
Results: Among 58 cases, there were 30 cases with inflammatory diseases; 6 cases with benign tumors; 8 cases with malignant tumors and 14 cases with fractures. The correct rate of CT diagnosis for location was 100%, and for the nature of the disease was 91.38%.
