Thyroid nodules are a common clinical condition, with benign nodules accounting for the majority of cases. At present, surgical resection and medication are the main treatments. Percutaneous radiofrequency ablation of thyroid nodules is a new method of tumor treatment developed at home and abroad in recent years. It is based on the precise percutaneous puncture of the ablation electrode into the lesion under ultrasound guidance, causing coagulative necrosis of the lesion tissue through the high temperature effect of the radiofrequency needle, and finally the necrotic tissue is absorbed by the body, thus achieving the purpose of minimally invasive local inactivation of the lesion and achieving the same effect as that of traditional surgery. The method is minimally invasive, does not require incision, leaves no scars on the skin surface, preserves the organs, does not affect the function of the thyroid gland, and has good repeatability in the treatment of new or recurrent lesions. The advantages of radiofrequency ablation of thyroid nodules compared with traditional surgical treatment: 1, outpatient treatment or only 1 to 2 days of hospitalization 2, local anesthesia, small impact on the whole body 3, small trauma, no surgical scars; beautiful 4, no damage to normal thyroid tissue, no hypothyroidism, no need to take medication for life after treatment Efficacy of radiofrequency ablation of thyroid nodules: The inactivated thyroid nodules can be significantly reduced in size or even absorbed after 6-12 months. After 6-12 months of absorption, the size of the nodules can be significantly reduced or even disappear. Indications for radiofrequency ablation of thyroid nodules: 1. nodules diagnosed as benign by needle aspiration cytology or coarse needle aspiration biopsy 2. nodules with obvious pressure symptoms, such as neck discomfort, pain, swallowing difficulties or even breathing difficulties 3. nodules that are not suitable for surgical removal or refuse surgery 4. nodules that are convex and affect the aesthetics or have high requirements for postoperative aesthetics 5. nodules that are overly anxious about the thyroid gland After nearly one year of follow-up review, the efficacy of the previous treatment has been shown, and the tumor has shrunk significantly, achieving the expected treatment effect.
