Thyroid nodules are a common condition, especially in young and middle-aged women. Thyroid nodules are divided into two categories: benign and malignant, with benign nodules accounting for the majority and malignant nodules for less than 1%. Thyroid nodules can be solitary or multiple, with a higher incidence of multiple nodules than solitary nodules. Thyroid nodules are usually small, ranging from a few millimeters to a few centimeters in size, and are usually diagnosed only when a thickening of the neck or an ultrasound is detected, except in nodules that function as thyroxin-producing nodules with “hyperthyroid” symptoms. The traditional treatment is surgical removal or even total thyroidectomy, but this has the disadvantage of requiring long-term oral thyroxine supplementation and leaving scars on the skin. With the maturity of ultrasonic interventional microwave ablation technology for liver cancer treatment, local ablation has become the first choice of effective treatment means, especially for early stage small liver cancer. It can also coagulate part of the thyroid tissue to reduce the amount of secretion, which is another method of treatment for hyperthyroidism. The treatment is performed under local anesthesia, with preoperative biopsy and postoperative ultrasonography evaluation and biopsy to determine the extent of ablation. The treatment is usually performed after 1-3 days of rest and the skin is only a pinpoint mark. At the same time, it is also the ultrasonic interventional ablation treatment reaching a higher level.
