This prospective randomized contralateral comparative study aims to compare electrocautery and scalpel incision techniques in upper eyelid blepharoplasty. Each participant undergoes bilateral upper eyelid blepharoplasty, with one eyelid randomized to electrocautery incision and the contralateral eyelid to scalpel incision. Outcomes include postoperative pain, edema, ecchymosis, scar quality, wound healing, patient satisfaction, and surgeon satisfaction. The study is designed to determine whether electrocautery provides comparable or superior clinical outcomes while maintaining safety and surgical effectiveness.
