Ablation of thyroid nodules is a method commonly used in clinical practice to treat thyroid lesions. It usually has the following disadvantages: First, thyroid nodule ablation is a method in which the ablation needle penetrates inside the nodule and local high temperature heating causes the nodule tissue to denature, necrotize, and dissolve and absorb itself. At this time, if the nodule is a malignant tumor, it can indeed kill the tumor cells, but it is not capable of clearing the surrounding lymph nodes. The tumor is very likely to recur after surgery, causing the patient’s condition to worsen. Secondly, because of the high local temperature of the thyroid puncture needle, different patients have different sensitivity to high temperature. Patients with poor tolerance may cause damage to the local recurrent laryngeal nerve, and patients may experience hoarseness after surgery. If the supraglottic nerve is damaged, patients may have complications such as choking and coughing on drinking water and reduced pitch, which seriously affect normal life.
