Abstract
PURPOSE: To address the efficacy, safety, and stability of frontalis suspension of the upper eyelid with a silicone band for the treatment of severe congenital ptosis in infants. METHODS: Data from 22 pediatric patients undergoing unilateral frontalis suspension with silicone band were retrospectively reviewed with a follow-up ranging from 18 to 30 months. The margin-reflex distance (MRD) and the corneal staining had been evaluated at each pre- and postoperative visit. Data were analyzed by analysis of variance and t test for paired data. RESULTS: MRD was absent before surgery in all cases: it ranged from -1 mm to -4 mm (-2.4+/-0.8 mm). Immediately after surgery, it increased to 2.9+/-0.3 mm, and then progressively reduced by 0.6 mm within the first 3 months (p=0.001); a further reduction of 0.2 mm, occurring between 3 and 12 months after surgery, was not statistically significant. After the 12-month visit, no changes in MRD were found at follow-up for any patient. Corneal staining, which was present in five patients over the first 2 postoperative weeks, recovered without sequelae. Complications occurred in three eyes: overcorrection and corneal ulcer in one case requiring removal of the silicone band, one granuloma, and one extrusion of the silicone band from the upper frontal incision. CONCLUSIONS: During the study period, the frontalis suspension with a silicone band was an effective and safe procedure. MRD values were stable between month 3 and the end of follow-up, although this series does not preclude the possible occurrence of blepharoptosis at longer time intervals.
