Thyroid ablation is mostly used for the treatment of benign thyroid nodules, or smaller suspected malignant nodules that have been confirmed to be free of lymphedema, solitary, and metastasis. Thyroid ablation is a minimally invasive treatment technique that utilizes ultrasound guidance to intervene the ablation needle into the thyroid nodule, generating localized high temperature through high-frequency microwave to ablate the diseased area. It is mainly used for the treatment of benign thyroid nodules, or smaller suspected malignant nodules that have been confirmed to be free of lymphoma, solitary, and metastasis. The advantages of thyroid ablation include less trauma, shorter operation time, etc., and the thyroid gland still functions well after the operation, which usually does not require long-term medication; the disadvantages are that the treatment may be incomplete, and malignant tumors cannot be treated. Whether a patient is suitable for thyroid ablation needs to be judged by the doctor according to the patient’s specific situation.
