A generator creates an electric circuit. The electrode is designed to optimally deliver energy to the area that is being treated. During the procedure, the doctor will place the tip of the probe into the thyroid nodule. The generator creates a high frequency wave and sends it directly to the end of the probe. Your doctor can then adjust the area being treated as needed to ensure that you achieve the desired results.
You will often hear background noise and “crackling” sounds throughout the procedure. These sounds are normal and signify an appropriate response is taking place.
