Thyroid tumor ablation therapy is an advanced ultra-minimally invasive treatment technique that causes minimal harm to thyroid function and does not require thyroid medication after the procedure. After local anesthesia, an ablation needle with a diameter of only 2-3mm is inserted directly into the thyroid tumor by percutaneous puncture under ultrasound surveillance, and radiofrequency/microwave energy is rapidly emitted locally to inactivate the tumor in situ. The operation time is more than 10 minutes to half an hour (the operation time varies according to the size and number of tumors). The patient can go home after the operation with about half an hour observation. Patients are painless and only small rice-grain sized pinholes are found locally, which will disappear in a few days. Indications for surgery: benign thyroid nodules and tumors (single greater than 2cm/multiple or less than 2cm patients with heavy psychological burden) recurrent thyroid tumors 1, in situ recurrence palliative treatment 2, thyroid cancer postoperative neck lymph node recurrence metastases before ablation thyroid nodules ablation (ablation needle visible under ultrasound) 3 months after ablation nodules mostly absorbed immediate postoperative neck wound (small pinhole).
