RF / Electocautery
Electrocautery, also known as thermal cautery, refers to a process in which a direct or alternating current is passed through a resistant metal wire electrode, generating heat. The heated electrode is then applied to living tissue to achieve hemostasis or varying degrees of tissue destruction. Electrocautery can be used in various minor surgical procedures in dermatology.
Low temperatures can be used for superficial tissue destruction in the treatment of superficial and relatively avascular lesions, including the following:
- Seborrheic Keratoses
- Acrochordons or Skin tags
- Dermatosis papulosa nigra (DPN)
- Small angiomas
A dermal curette may be used concurrently to remove the lesion.
Higher temperatures are effective in removing thicker skin lesions, such as the following:
- Sebaceous Hyperplasia
- Pyogenic Granulomas
