Strategy of Out-Fold Double Eyelid Corrected Into In-Fold: Low Position Design, Direction Control Suture, and Fat Transfer.

[BACKGROUND] Double eyelid surgery is a common but delicate cosmetic procedure in Asia. Because of the precise requirements and technical reasons, patients who received blepharoplasty may not satisfied with their out-fold crease. Some patients are born with unsatisfied out-fold double eyelids. The medial creases of double eyelid were higher than should be.

[OBJECTIVES] In this study, the authors developed a strategy to correct out-fold crease of double eyelid to in-fold to satisfy patients' requirements.

[METHODS] From January 2022 to May 2024, 102 patients (96 females and 6 males) were included in this retrospective analysis. Patients with out-fold double-eyelid inborn or obtained. The patients were divided into 3 groups: inborn out-fold double-eyelid, obtained double-eyelid with epicanthus, and obtained double-eyelid without epicanthus. The surgical strategy contained low position design, direction control suture, and fat transfer. Preoperative and postoperative images were collected, and patients' satisfaction and complications were evaluated.

[RESULTS] In total, 102 consecutive patients were included in this study, with an average follow-up of 11.9 months. Eleven patients had inborn out-fold creases, and 83 patients had out-fold creases with epicanthus after primitive blepharoplasty, and 8 patients had out-fold creases without epicanthus after primitive blepharoplasty. Ninety-six (94.12%) patients were satisfied with their results. Complications included narrow double eyelid width (n =1, 0.98%), asymmetric creases (n=2, 1.96%), incompletely in-fold creases (n=3, 2.94%), and subtle fork in medial creases (n=4, 3.92%).

[CONCLUSIONS] The surgical strategy, which contained low-position design, direction control suture, and fat transfer, could correct out-fold creases of double-eyelid into in-fold effectively.
