Abstract

Objective: This study was conducted to evaluate the effectiveness of the technique of shortening the orbicularis oculi muscle combined with lower eyelid fat reposition to rejuvenate the lower eyelid area. Surgery was performed at the Oculo plastic and Reconstructive Department, Vietnam National Eye Hospital from October 2023 to May 2024. Research subjects and methods: Uncontrolled descriptive intervention study on a group Patients were diagnosed with grade D, E, F tear trough, grade 4, 5 hypertrophic fat sac, orbicularis oculi hypertrophy, fat herniation or loss of eyelid area continuity. Results: Male: female ratio 1:3, average age of the study patient group was 54.7 ± 6.15 years old, of which 70% of patients were in the age group 40-60 years old. The average orbital tilt angle before surgery was 130.4 degrees, after surgery it increased to 180.7 degrees. Before surgery, 100% of patients had normal lower eyelid position and eyelid margin. After surgery, 97.5% of patients had mild lower eyelid retraction. 95% of patients with moderate and marked lower eyelid fat bag prolapse were resolved after surgery. Conclusion: The method of shortening the orbicularis oculi muscle combined with lower eyelid fat reposition is effective in rejuvenating the lower eyelid area
