RESUMO
PURPOSE: This study was undertaken to determine the amount of ptosis correction in congenital unilateral ptosis patients who had been performed frontalis suspension with autologous fascia lata under general anesthesia. METHODS: The subjects consisted of 27 patients with unilateral ptosis who had been performed frontalis suspension with autologous fascia lata under general anesthesia. At 1,4,8,and 12 weeks, the width of interpalpebral fissure was measured with videocamera. RESULTS: The mean preoperative interpalpebral fissure was 3.9+/-1.2 mm. At intraoperation, the mean interpalpebral fissure was 4.5+/-0.4 mm. The mean postoperative interpalpebral fissures were 6.8+/-0.6 mm, 7.8+/-0.8 mm, 6.8+/-0.8 mm, and 6.7+/-0.8 mm at 7+/-1, 29+/-3, 57+/-4, and 96+/-9 days. In preoperative severe ptosis group (ptosis amount 4 mm), the mean postoperative interpalpebral fissure was smaller than the other group. CONCLUSIONS: The postoperative interpalpebral fissure was stabilized after the 2-month follow-up. The results of this study suggest that the amount of ptosis correction should be modified in consultation with preoperative ptosis amount.
