The incidence of thyroid nodules has increased significantly, especially the incidence of malignant nodules. If not limited by the level of the doctor, ultrasound examination can distinguish 80% of nodules as benign or malignant, while 20% of nodules that cannot be identified need ultrasound-guided puncture biopsy to clearly identify the nature of the nodules. With the rapid development of medical technology, ultrasound-guided radiofrequency minimally invasive treatment of benign thyroid nodules has received very satisfactory results, and patients who have been treated by our hospital have given very satisfactory comments. With minimally invasive ultrasound treatment, benign thyroid nodules can be treated without having to wait until they grow and become malignant before undergoing surgery. The inactivated nodules will be absorbed and disappear after a period of time (as short as six months or as long as one or two years, depending on age and individual differences). Ultrasonic radiofrequency minimally invasive treatment can also treat lymph nodes that have metastasized and recurred after thyroid cancer surgery, and the results are very good. For malignant nodes, surgery should be performed as soon as possible because although thyroid cancer grows slowly, the later it is treated, the greater the chance of metastasis and the worse the prognosis.
