This study was conducted to evaluate the effectiveness of the technique of the levator muscle resection combined with transverse superior fasscial expansion (TSFE) in the treatment of patients with severe congenital ptosis at the Department of Eye and Facial Reconstruction and Plastic Surgery, Vietnam National Eye Hospital. Research subjects and methods: Uncontrolled descriptive intervention study on a group of patients with severe congenital ptosis. Select a convenient sample size with a sample size of 30 eyes. The study was conducted at the Oculoplastic and reconstructive Department, Vietnam National Eye Hospital. Results: 22 patients with 30 eyes with severe congenital ptosis were operated by the levator muscle resection combined with transverse superior fasscial expansion (TSFE). Ratio male: female = 1.2:1, lowest age is 2 years old, highest age is 19 years old. The average MRD1 before surgery was 0.67 0,33 mm, the average MRD1 after surgery was 3.25  0,25 mm. After 6 months of follow-up, only 1 patient had entropion of the eyelid causing damage to the ocular surface requiring re-surgery. The curvature of the eyelid margin and upper folds are balanced on both sides. Conclusion: The method of of the levator muscle resection combined with transverse superior fasscial expansion is a safe and effective method for patients with severe congenital ptosis. The extended upper fascia material is an autologous material, thus limiting the complications of material rejection and infection, is cheap, and is suitable for many types of patients.
