What is Radiofrequency Ablation?

Using radio frequency waves, radiofrequency ablation cauterizes thyroid nodules and cysts from inside the nodule. Performed under local anesthesia, radiofrequency ablation is relatively painless and does not require general anesthesia.

Doctors use guided ultrasound to insert a thermal probe into the thyroid nodule. Through selective heating of the probe tip, the nodule is cauterized. The cauterized tissue is then broken down by the body over the course of months.
