Fulguration is a technique that utilizes what form of energy?

1. Ultrasound

2. High frequency (sparking)

3. Laser

4. Radiofrequency

The correct answer is: High frequency (sparking)

Fulguration is a technique that utilizes high-frequency electrical currents to produce a spark, which effectively cauterizes or destroys tissue. This method is often employed in dermatological treatments to remove growths like warts or skin tags and for various cosmetic procedures. High-frequency energy causes a rapid oscillation of charged particles, which generates heat, leading to tissue vaporization or coagulation. The sparking action associated with this technique is key, as it allows for precise and controlled treatment with minimal impact on the surrounding skin. This distinguishes fulguration distinctly from other modalities, such as lasers that utilize focused light energy or ultrasound that operates through sound waves. While radiofrequency also uses electrical energy, it does so in a different manner, primarily for deeper tissue heating rather than the surface tissue effects characteristic of fulguration.
