How is radiofrequency ablation performed?

The procedure is performed by placement of needles into the area of abnormality. Usually we'll give you a local anaesthetic into the skin prior to placement of these needles. Once the needles are placed in an appropriate position, then the radiofrequency generator is turned on, which provides the radiofrequency energy. When the radiofrequency energy is applied, then we follow the mast and the temperature or the resistance within the mast in order to determine if the tumour is fully treated.
