| Objective:To explore CT imaging features of nasal cavity lesions, and further improve the diagnostic level.Materials and Methods:Collected 291 cases of nasal CT scans, of which 96 cases of nasal mass lesions were confirmed by pathology or clinical; nasal anatomic variations /normal in 195 patients. In the total 291 cases, there were 155 cases of male and 136 cases of women; age of 21 to 62 years old. There were 247 cases of CT plain scan, and CT scan plus contrast CT scan in 44 cases.Results:291 patients were divided into group of nasal with mass lesions and group of nasal anatomic variations/normal.(1) Group of nasal with mass lesions:1,In 76 cases of benign tumor, there were 6 cases associated with bone breaker; in 20 cases of malignant tumors, there are 19 cases associated with bone destruction; byχ2 test,χ= 57.93, P= 0.000, there was statistical disparity between these tow groups.2,In 76 cases of benign tumor, there were 12 cases associated with bone resorption; in 20 cases of malignant tumors, there is 0 case associated with bone loss; byχ2 test,χ= 2.31, P= 0.129> 0.05, there was not significant disparity between these tow groups.(2) Group of nasal anatomic variations/normal: In 195 cases, there were 128 cases with chronic nasitis or sinusitis, of which 76 cases with ostiomeatal complex (OMC) Variation; in 67 cases of normal sinus, there were 22 cases with OMC mutation; byχ2 test,χ= 10.66, P= 0.001, there was significant statistical disparity between these tow groups.Conclusion:Most of the nasal cavity mass can be exactly diagnosis with CT scan, and the etiological factor of sinusitis can be identified, and it is helpful to guide the development of surgical programs. |
