Purpose. To describe the long-term results of frontalis suspension using autogenous fascia lata in children with congenital ptosis under 3 years old. Methods. Forty three-eyes of 35 patients were enrolled in the study. Frontalis suspension using autogenous fascia lata was performed in all patients. The postoperative eyelid level, ptosis recurrence, visual acuity, and cosmetic results were evaluated. Results. The mean age of the patients was 16.8 ± 9 months (7–36 months). The mean follow-up time was 52.8 ± 15 months (14–95 months). All patients had good (ptosis <2 mm) or moderate (2-3 mm ptosis) eyelid level after the operation. All patients achieved satisfactory cosmetic results. Succesfull harvesting was performed in all cases and no additional materials or surgical manipulation were needed during the surgery. Conclusion. Frontalis suspension using autogenous fascia lata can be used in children under 3 years old without harvesting problems. Surgical experience and good knowledge of anatomy are important factors for successful results after the surgery
