    <primary_outcome>
      <prim_outcome>Thyroid nodule volume reduction rate: It is created by dividing the difference between the pre- and post-thyroid nodule volume by the pre-thyroid nodule volume multiplied by 100. Timepoint: The volume of the thyroid nodule or lymph node is examined first and 3 and 6 months after the procedure. Method of measurement: The size of the thyroid nodule or lymph node is determined by ultrasonography of the thyroid or neck.</prim_outcome>

      <sec_outcome>Minor and major complications resulting from ultrasound-guided radio frequency ablation procedure. Timepoint: Beginning of study, 3 and 6 months after the procedure.
