Abstract:
Objective To investigate the value of high frequency ultrasound and CT in the diagnosis of laryngeal carcinoma. Methods Sixty-nine cases of laryngeal carcinoma were typed and staged by high frequency ultrasound and CT, and compared with the results of laryngoscopy and postsurgical pathology. Results The typing accuracy was ~94.2 % for ultrasonography and ~91.3 % for CT, higher than that of laryngoscopy(~73.9 %).T staging accuracy of ultrasonography was T_1 ~85.9 %,T_2 ~88.5 %,T_3 ~94.1 % and T_4 ~88.9 %, higher than that of CT (~68.8 %) and laryngoscopy (~75.0 %) in T_3 stage and superior to laryngoscopy (~66.7 %) in T_4 stage. Lymph node metastases were found in 37 cases (~53.6 %) by ultrasonography, higher than those by CT scanning (~27.5 %). Color Doppler blood flow laryngeal carcinoma was shown in 65 cases(~94.2 %),most were low resistance spectrum pattern. Conclusions High frequency ultrasonography is superior to CT and laryngoscopy in the staging of laryngeal carcinoma and is of great value in choosing the therapeutical protocol.
