Abstract：Objective To detect the clinical value of ultrasonography before operation in predicting cervical lymph node me-tastasis of thyroid micropapillary carcinoma.Methods 90 patients with thyroid micropapillary carcinoma from January in 2020 to June in 2023 were selected,including 42 patients with cervical lymph node metastasis as the study group,and 48 patients without cervical lymph node metastasis as the control group.All the patients were examined by ultrasonography,the number of the lesions were evaluated,the diameter and aspect ratio were measured,and the shape of the nodule,the border of the nod-ule,the echo of the nodule,the microcalcification,the invasion of the capsule and the internal blood supply were observed.Results The main ultrasonographic features were hypoechoic,microcalcification,cystic change and abundant internal blood flow.The multiple,diameter(≥5 mm),aspect ratio(≥1)and percentage of lesions in the study group were 47.62%,80.95%,69.05%respectively,higher than those in the control group 14.58%,14.58%,20.83%,the difference was statistically significant(P<0.05).Conclusion The detection of papillary thyroid carcinoma by ultrasonography can predict the cervical lymph node metastasis by observing and analyzing the ultrasonic signs.
