Abstract
Objectives
To compare the outcome of silicone sling frontalis suspension (FS) surgery in children with isolated uncomplicated congenital ptosis (IUCP) vs. children with complicated ptosis.
Methods
A retrospective medical chart review of all pediatric patients who underwent silicone sling FS surgery between 2009–2020 at a single center were included. Patients were divided according to ptosis type: IUCP vs. complicated ptosis. Pre-and post-operative margin-to-reflex distance (MRD1) measurements were determined from clinical photographs. Main outcome measures were differences in improvement in eyelid height, reoperation rate, and timing between the groups.
Results
Two-hundred and eight children were included: 139 IUCP and 69 complicated cases, 83 females (40%), mean (± SD) age at intervention was 1.9 ± 2.9 years. Complicated cases included: blepharophimosis epicanthus inversus syndrome (n = 35), Marcus Gunn jaw winking (n = 12), oculomotor palsy (n = 8), congenital fibrosis of extraocular muscles (n = 3), chronic progressive external ophthalmoplegia (n = 3), and others. Mean MRD1 improved by an average of 1.6 mm in both groups. Repeat ptosis repair was performed in 50/171 (29%) patients without a history of failed ptosis procedures, and this rate was similar between IUCP and complicated cases. Children under 3 years of age had higher rates of repeat ptosis repair than older children (n = 59/175, 34% vs n = 5/33, 15%, p = 0.03 chi2).
Conclusions
Silicone sling frontalis suspension has a favorable outcome in 70% of pediatric patients. Preoperative and final MRD1 and reoperation rates were similar between both groups, suggesting that despite the higher complexity in atypical cases, the outcome is similar.
