Stability of silicone band frontalis suspension for the treatment of severe unilateral upper eyelid ptosis in infants.
OBJECTIVE
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.
