Two forms of electrosurgery: (A) Electrodesiccation with an active electrode tip touching the skin and showing penetration of planned tissue damage. (B) Fulguration with sparking from electrode to tissue. Treatment area is more superficial than in desiccation.


Fulguration, also called electrofulguration, is the destruction of tissue by means of a high-frequency electric current applied with a needlelike electrode. In fulguration, the electrode is held away from the skin to produce a sparking at the skin surface and more shallow tissue destruction Fulguration is especially useful in treating superficial epidermal lesions, such as a superficial basal cell carcinoma of the trunk.[1]
