Objective To compare the effects between the "window method" of orbicularis oculi muscle incision and the traditional Park method for double eyelid surgery. Methods A total of 76 patients who underwent double eyelid surgery in the Department of Aesthetic Surgery of Huamei Aesthetic & Plastic Hospital from February 2024 to May 2025 were selected as the research subjects, and they were divided into the reference group and the experimental group according to the difference in surgical methods, with 38 patients in each group. The reference group received traditional Park method for double eyelid surgery, and the experimental group received the "window method" of orbicularis oculi muscle incision for double eyelid surgery. The surgical related indicators, eyelid status, aesthetic satisfaction and complication rate were compared between the two groups. Results The operation time, suture removal time and postoperative recovery time of the experimental group were shorter than those of the reference group, and the intraoperative blood loss and scar score were lower than those of the reference group (P <0.05). At 7 days after surgery, the palpebral fissure height and levator palpebrae superioris muscle strength of the experimental group were higher than those of the reference group, and the eyelid width was lower than that of the reference group (P <0.05). The aesthetic satisfaction rate of the experimental group (94.74%) was higher than that of the reference group (76.32%) (P <0.05). The incidence of complications in the experimental group (2.63%) was lower than that in the reference group (18.42%) (P <0.05). Conclusion Compared with the traditional Park method for double eyelid surgery, the "window method" of orbicularis oculi muscle incision for double eyelid surgery has a better application effect. It has a good effect on accelerating postoperative recovery and reducing scar severity, can also reduce the risk of complications, improve patients' eyelid width and palpebral fissure height, and is conducive to improving aesthetic satisfaction.
