Thyroid nodule ablation is a type of treatment in which the nodules are necrotic through radiofrequency ablation. Thyroid nodule ablation involves the insertion of a radiofrequency needle into the nodule via ultrasound, which generates heat energy when energized, causing the nodule or lesion to coagulate and necrose to achieve the therapeutic goal. Radiofrequency ablation has small wounds and less bleeding, and can treat benign thyroid nodules. It is also currently used to treat early malignant lesions, but there is a possibility of recurrence. Thyroid function should be monitored after ablation of thyroid nodules, once hypothyroidism occurs, it is necessary to consult a doctor in time, under the guidance of the clinician.
