Lower eyelid blepharoplasty is one of the most popular aesthetic procedures. Electrocautery provides a hemostatic benefit for skin incision; however, its effect on scar cosmesis remains unclear, particularly in Asian skin types. We compared the Colorado needle electrocautery (pure-cutting mode) versus the traditional scalpel in terms of efficacy, complications, and cosmetic outcomes.
A prospective intraindividual randomized controlled trial was conducted to compare the efficacy of Colorado needle electrocautery and scalpel in lower blepharoplasty. The study outcomes were scar quality at different times until 1 year postoperatively, bleeding during incision, and postoperative ecchymosis. Scar quality was evaluated using 3 standard scar ratings: the Vancouver Scar Scale, Patient and Observer Scar Assessment Scale, and Hollander wound evaluation scale.
The study included 25 patients, and the electrocautery side had less blood loss during incision than the scalpel side (2.6 ± 0.65 versus 5.28 ± 0.68 sticks; < 0.001). The electrocautery side had less postoperative ecchymosis ( < 0.001); however, 1-year scar quality was not statistically significant between the groups.
Colorado needle electrocautery pure-cutting mode can be an alternative to the traditional scalpel for lower eyelid blepharoplasty skin incision because of long-term scar quality. Electrocautery also has hemostatic benefits, leading to a decrease in intraoperative and postoperative bleeding.
下睑整形术是最受欢迎的美容手术之一。电灼术对皮肤切口有止血作用；然而，其对瘢痕美容效果的影响仍不明确，尤其是在亚洲人种皮肤类型中。我们比较了科罗拉多针电灼术（纯切割模式）与传统手术刀在疗效、并发症及美容效果方面的差异。
进行一项前瞻性个体内随机对照试验，以比较科罗拉多针电灼术和手术刀在下睑整形术中的疗效。研究结果包括术后1年内不同时间点的瘢痕质量、切口出血情况及术后瘀斑。瘢痕质量采用3种标准瘢痕评分进行评估：温哥华瘢痕量表、患者和观察者瘢痕评估量表以及霍兰德伤口评估量表。
该研究纳入25例患者，电灼术一侧切口时的失血量少于手术刀一侧（2.6±0.65次与5.28±0.68次；<0.001）。电灼术一侧术后瘀斑较少（<0.001）；然而，两组间1年时的瘢痕质量无统计学差异。
由于长期瘢痕质量，科罗拉多针电灼术纯切割模式可作为下睑整形术皮肤切口传统手术刀的替代方法。电灼术还具有止血作用，可减少术中及术后出血。
