Electrobrasion
Electrobrasion
In a case series of 6 patients, Burns et al. introduced electrosurgical skin resurfacing as a safe and effective alternative to dermabrasion for scar treatment.7 Scars were treated with a bipolar electrosurgical device 3 to 8 weeks following Mohs surgery and evaluated with a comparison of photos taken at 1 and 2 weeksโ and at 1, 3, and 6 monthsโ post treatment. Patients also completed a questionnaire after 6 months. Burns found that all 6 scars showed improved topography and color match, and all patients thought the procedure had helped. Burns also performed a histological evaluation to assess depth of tissue penetration and residual thermal injury created by the electrosurgical device. Redundant standing cutaneous cones from Mohs procedures were treated with a different combination of power levels and number of passes and then excised for histopathologic examination. Burns found the mean depth of injury was 114.1 ยตm (SD = 60.7 ยตm), with minimal difference between the different power settings
and number of passes. The electrosurgical effect did not extend to the level of hair bulbs or deeper eccrine ducts, preserving the population of stem cells needed for skin regeneration.
