Abstract:
Objective To evaluate the value of color Doppler ultrasonography in the diagnosis of laryngeal carcinoma. Methods Thirty-six cases of laryngeal carcinoma were typed and staged by color Doppler ultrasonography and compared with the findings of laryngoscopy and postsurgical pathology.Results The typing accurate rate of color Doppler ultrasonography to laryngeal carcinoma was 100%. The staging accurate rate of color Doppler ultrasonography to laryngeal carcinoma was T 1 77.8%, T 2 94.2%, T 3-T 4 100%, respectively. Color Doppler flow imaging showed irregular signals of blood stream in the interior and the circumference of the tumor and signals of perforating blood stream in the interior of the tumor. Artery flow spectrum was showed by pulse wave Doppler. Conclusions Color Doppler ultrasonography can apparently improves accuracy of staging to laryngeal carcinoma and is quite important in choosing clinical therapy of laryngeal carcinoma.
