Electrosurgery in dermatology

Electrosurgery applies high frequency alternating electrical currents to generate heat, thereby creating tissue damage required for cutting, hemostasis, or destruction. Electrosurgery can be delivered in a variety of different ways and can be tailored to achieve the desired clinical effect. Having a command of the underlying principles of electrosurgery will help dermatologic surgeons use the appropriate form of electrosurgery to safely achieve the desired results. We reviewed basic principles of electrosurgery, described the various techniques and devices, and delineated associated risks of electrosurgery for specific patient populations and providers. All modalities of electrosurgery present a risk of electromagnetic interference, which can negatively affect patients with implanted devices, such as pacemakers, defibrillators, cochlear implants, and deep brain stimulators. In particular, electrosurgery may create a smoke plume containing a number of volatile organic compounds potentially noxious; however, the risk of such exposure remains unknown.
