Abstract
Objective: To analyze the imaging features of unilateral maxillary sinus nasal lesions and the selection of treatment strategies based on imaging findings for these lesions. Method: The CT and enhanced MRI data of 64 cases of unilateral maxillary sinus and nasal lesions were selected. The imaging findings and surgery approach were observed and recorded. To summarize the imaging characteristics and analyze the choice of treatment strategy. Result: All 64 Unilateral maxillary sinus nasal lesions presented a roughly uniform soft tissue density shadow on CT. In all benign lesions, there were 9 cases manifested maxillary sinus wall bone destruction and bone discontinuity(18.4%,9/49); There were 17 cases of bone hyperplasia (34.7%,17/49).Bone destruction was observed in 14 cases of all malignant lesions (93.3%, 14/15). The appearance is approximately uniform signal shadow on MRI T1WI images. The lesions with different properties of the enhanced T1 images showed the imaging manifestations with their own characteristics. According to the CT and enhanced MRI images, the designed treatment plan was divided into 5 types. The coincidence rate of operation and plan was 90.5%,there were 4 cases of temporary modification in operation. Conclusion: For unilateral lesions, preoperative enhanced MRI and CT scan should be included as routine examination. CT is clear for bone observation, and can be the nature of tumor and germinal center. Enhanced MRI can provide more accurate information on the lesion scope, blood supply and the relationship between mass and surrounding tissues. Combined with the preoperative imaging data, it can provide the basis for the operation plan and treatment strategy of unilateral lesions.
