Radio Frequency Surgery


Radio frequency surgery is a medical procedure in which a skin growth is ablated using the heat generated from the high frequency alternating current. The principle of radiofrequency or radiowave surgery is that it uses high frequency radiowaves, at 4.0 MHz, to deliver low temperatures through radiofrequency (RF) micro-fibre electrodes. Radio Surgery (Radiofrequency or Radiowave Surgery) is used to remove moles, warts, skin tags and other so called ‘lumps and bumps’. Traditional electrosurgery devices cut skin tissue by passing an electric current using the electrode tip (a platinum wire) to provide resistance, effectively causing high temperature heating of the electrode tip and excessive lateral (surrounding) tissue damage. The difference between this method and electrosurgery is that the tissue serves as the resistance instead of the electrode. This means there is no heating of the RF micro-fibre electrode by the use of low temperature radiowave energy. Instead, the intracellular tissue water provides the resistance and vaporises without the heat and damage seen in electrosurgery. This tissue vaporisation also results in significant haemostasis (stopping of the flow of blood) without actually burning the tissue. There is minor swelling, redness, & scab in the area for 1-3 days as it heals.
