Abstract

This case series reports the first application in Vietnam of the levator–frontalis muscle advancement flap technique for treating severe congenital ptosis. Four patients with poor levator function (≤ 4 mm) underwent surgery at the Vietnam National Eye Hospital in 2025 and were followed for at least four weeks postoperatively. The procedure resulted in a marked improvement in eyelid position, with the mean MRD1 increasing from -0.6 mm before surgery to 2.8 mm after surgery. All patients developed symmetric and well-defined eyelid creases with aesthetically pleasing eyelid contours. While mild lagophthalmos was noted in some cases, it tended to improve over time, and no significant corneal complications were observed. These findings suggest that the levator–frontalis muscle advancement flap is a promising surgical option for severe congenital ptosis, yielding favorable functional and cosmetic outcomes. However, further research with larger patient cohorts and extended follow-up is necessary to validate the long-term efficacy and safety of this technique.
