Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Radio frequencies at non-ablation energy levels are commonly used as a part of aesthetic treatments that can tighten skin, reduce fat by lipolysis and also apoptosis, [4] or promote healing. [5] RF diathermy is a medical treatment that uses RF induced heat as a form of physical therapy and in surgical procedures. It is commonly used for muscle ...
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
The technique for thermal ablation in the lung by using radiofrequency ablation was first described in 1995 for use in animal lung tumor models and then in 2000 in humans. [1-2] Microwave ablation has emerged as a newer ablation modality and an addition to the arsenal of minimally invasive cancer care.

Cryoablation has been explored as an alternative to radiofrequency ablation in the treatment of moderate to severe pain in people with metastatic bone disease.The area of tissue destruction created by this technique can be monitored more effectively by CT than RFA, a potential advantage when treating tumors adjacent to critical structures.
The word coblation is short for ‘controlled ablation’, which means a controlled procedure used to destroy soft tissue. [3] This procedure uses low temperature radio frequency during the operation, which was found to cause less pain for the patient than previous technologies used for tonsillectomy.
Where solar radiation is the dominant cause of snow ablation (e.g., if air temperatures are low under clear skies), characteristic ablation textures such as suncups and penitentes may develop on the snow surface. [6] Ablation can refer to mass loss from the upper surface of a glacier or ocean-driven melt and calving on the face of a glacier ...
