Radiofrequency ablation (RFA) is a minimally invasive technique that uses a probe the size of a needle to shrink thyroid nodules using alternating frequencies and heat. The technique has been used in Europe and Asia, but is relatively new in the United States. Nodules can decrease in size by 30-80%, depending on the type. Most patients do not require thyroid medicine after the procedure and there are few side effects. Patients may be asked to remain NPO (nothing to eat after midnight) for the procedure and may be given light anesthesia sedation, similar to what is given for a colonoscopy procedure.
*We currently do not perform RFA in our clinic. There are only a few centers nationwide that do.
