Comparison of Colorado Needle Electrocautery and Traditional Scalpel for Lower Eyelid Blepharoplasty Incision: A Randomized Controlled Trial.

Background: 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.
