Abstract：Objective:To analyze and compare the value of coronal and axial CT scan in the diagnosis of nasal and paranasal malignant tumors. Method:50 patients with malignant tumors of nasal cavity and sinuses admitted to Guizhou Provincial People's Hospital from January to December 2023 were selected as the study objects,and the patients were diagnosed by coronal and axial CT scan respectively. Using the results of pathological examination as the gold standard,the diagnostic accuracy of coronal and axial CT scan for malignant tumor types and stages of nasal sinus was compared. Result:32 cases of epithelial tumors,11 cases of mesenchymal tumors and 7 cases of neuroendocrine tumors were pathologically detected. 32 cases of epithelial tumors,10 cases of mesenchymal tumors and 6 cases of neuroendocrine tumors were detected by coronal plain scan of sinus. 26 cases of epithelial tumors,11 cases of mesenchymal tumors and 7 cases of neuroendocrine tumors were detected by axial CT plain scan. The diagnostic accuracy of coronal CT scan was higher than that of axial CT scan for malignant tumors of nasal cavity and sinuses,and the difference was statistically significant (P<0.05). The diagnostic accuracy of coronal CT scan was higher than that of axial CT scan in T1,T2,T3,T4a and T4b stages of nasal and sinus malignant tumors,and the difference was statistically significant (P<0.05). Conclusion:Compared with axial CT scan,coronal CT scan is more valuable in the diagnosis of nasal and paranasal malignant tumors,which can better show the location,size,invasion range and bone destruction of the tumors.
