Electroabrasion, which uses an in-office electrosurgical device, is a method of surgical planning that ablates the skin to the papillary dermis. Several reports demonstrate that intraoperative ablative interventions with lasers or dermabrasion can modulate scar formation more effectively. This investigation uses electroabrasion intraoperatively to mitigate scar formation.
To evaluate the effectiveness of intraoperative electroabrasion for scar revision.
This was a prospective, randomized, observer-blinded, split-scar study with 24 linear scar segments resulting from primary closures in patients undergoing Mohs micrographic surgery. After placement of dermal sutures, half of the wound was randomly treated with electroabrasion. The other half was used as the control. Scar appearance was assessed by a blinded observer and by the patient using the Patient and Observer Scar Assessment Scale at 1 to 2 weeks, 1 month, and 3 months after surgery.
At the 3-month follow-up, both patient and observer variables measuring scar contour improved on the treated side, whereas erythema was worse. Overall, no difference was seen in total scores between the 2 sides.
Based on this pilot study, scars treated with electroabrasion revealed improved surface topography but worsened erythema. Future studies with more refined electrosurgical settings are needed for further evaluation.
电磨蚀术使用一种在办公室使用的电外科设备，是一种将皮肤烧蚀至乳头真皮层的手术规划方法。有几项报告表明，术中使用激光或磨皮术进行消融干预可以更有效地调节疤痕形成。本研究使用电磨蚀术术中减少疤痕形成。
评估术中电磨蚀术治疗疤痕的有效性。
这是一项前瞻性、随机、观察者盲法、分割疤痕的研究，共有 24 个线性疤痕段，源自接受 Mohs 显微外科手术的患者的原发性闭合。放置真皮缝线后，随机将一半的伤口用电磨蚀术处理。另一半作为对照。术后 1 至 2 周、1 个月和 3 个月，由盲法观察者和患者使用患者和观察者疤痕评估量表评估疤痕外观。
在 3 个月的随访中，测量疤痕轮廓的患者和观察者变量在治疗侧均有所改善，而红斑恶化。总体而言，两侧的总评分无差异。
基于这项初步研究，用电磨蚀术治疗的疤痕显示出改善的表面形貌，但红斑恶化。需要进一步评估更精细的电外科设置的未来研究。
