Abstract: Objective: To explore and analyze the CT imaging features of common benign and malignant tumors in oral and maxillofacial regions, and to evaluate the diagnostic efficacy of CT in oral and maxillofacial tumors. Methods: A total of 120 patients with benign tumors and 90 patients with malignant tumors admitted to the Department of Oral and Maxillofacial Surgery, the First Affiliated Hospital of Bengbu Medical College from January 2019 to June 2021 were selected. Combined with preoperative CT images, the difference between CT and pathological diagnosis was compared and analyzed, and the diagnostic efficiency of CT for benign and malignant oral and maxillofacial tumors was discussed. Results: The diagnostic accuracy of CT for benign oral and maxillofacial tumors was 86.7 %, and that for malignant oral and maxillofacial tumors was 84.4 %. CT examination had a high diagnostic rate for both benign and malignant tumors of oral and maxillofacial soft and hard tissues. Unenhanced CT combined with enhanced CT could effectively reduce the missed diagnosis rate and enhance the diagnostic efficiency. Conclusion: CT examination is one of the important means for the diagnosis of oral and maxillofacial tumors, which has guiding significance for clinical diagnosis and treatment plan formulation.
