Radio Surgery

Radiofrequency ablation (RFA) has gained importance in the recent years as it is highly effective in the cutting of the skin lesions with adequate hemostasis at the same time because of good coagulation. Radiofrequency can be used for incisional techniques that produce full-thickness excision of nevi, shave techniques that produce partial-thickness removal of superficial lesions and removing vascular lesions such as hemangiomas or pyogenic granulomas.Radiofrequency works on the principle of increasing the frequency and voltage while simultaneously decreasing the amperage of alternating current so as to generate oscillating radiowaves. These radiowaves are further modified to produce different waveforms that are passed into the lesion. Modern high-frequency radiosurgical devices transfer electrical energy to human tissue via a treatment electrode that remains cool.

The following conditions are treated successfully by this method,

• Skin tags

• Warts

• Cutaneous horn

• Cysts and mucocele

• Verrucous naevus

• Seborrhoeic keratoses
