Abstract

Objective: To evaluate the efficacy and safety of frontalis muscle flap advancement (FMFA) in the management of recurrent ptosis after levator resection or sling suspension. Methods: A prospective interventional study was conducted on 16 pediatric patients (20 eyes) with recurrent ptosis after prior surgery, treated with FMFA between June 2022 and August 2023 at Ho Chi Minh City Eye Hospital. Clinical variables included MRD, visual acuity, levator function, severity of ptosis, postoperative anatomical and aesthetic outcomes, and complications. Results: The mean age was 8.94 ± 2.29 years (range 6–15), with equal male-to-female ratio. Mean recurrence time after previous surgery was 11.5 ± 2.61 months. Preoperative MRD averaged 0.55 ± 1.09mm (–2 to 2mm). At 6 months postoperatively, MRD improved to 3.15 ± 0.81mm (p<0.001). Anatomical success: optimal correction in 75%, undercorrection in 25%, with no overcorrection or recurrence. Mean aesthetic score was 7.25 ± 1.21, with 90% rated as “good.” Complications included hematoma (10%) and mild entropion (10%), with no cases of lagophthalmos, lid retraction, or forehead hypoesthesia. Conclusions: FMFA is a safe and effective surgical option for recurrent ptosis, providing high anatomical and aesthetic success rates.
