Effect of Orbicularis Oculi Muscle Suspension Combined With Overlap in Modified Sub-Brow Blepharoplasty: A Prospective Study.

Background: Sub-brow blepharoplasty (SBB) has emerged as one of the primary methods for addressing periorbital aging among East Asian women in recent years. Numerous surgeons have continued to refine and innovate this technique; however, challenges remain in maintaining the stability of surgical outcomes and addressing issues such as abnormal postoperative eyelid wrinkles.

Objective: This study aims to conduct a prospective clinical investigation to demonstrate that improvements in SBB techniques can lead to enhanced postoperative eyelid morphology and sustained long-term results.

Method: Between September 2021 and September 2022, we included 72 female patients who underwent the modified SBB procedure. In addition to recording baseline data prior to surgery, we evaluated surgical outcomes postoperatively using both subjective and objective items.

Result: The average age of the patients was 47.69 years, with a median grade of 2 for upper eyelid skin laxity. The mean length of excised tissue was 44.72 mm, while the average width was 9.66 mm. No significant differences were observed in the vertical distance from the superior brow edge to the center of the pupil at 6 and 12 months postoperation, measured at the inner edge of the iris, the center of the pupil, and the lateral canthus. Similarly, the GAIS scores showed no significant differences at 6 and 12 months postoperation.

Conclusion: In this study, the improved SBB technique successfully reduced or eliminated abnormal postoperative eyelid creases, ensuring stable outcomes and an aesthetically pleasing appearance.
