PURPOSE: To compare long-term ophthalmic outcomes in infants treated for unilateral coronal synostosis (UCS) by endoscopic strip craniectomy (ESC) and helmet therapy with those treated by fronto-orbital advancement (FOA). METHODS: Consecutive patients with UCS, uncomplicated by other suture synostosis, were identified by a retrospective review of medical records. Assessment of presence of amblyopia, cycloplegic refraction, strabismus, and strabismus surgical intervention at all visits was recorded. RESULTS: Between 2004 and 2010, 22 patients were treated by FOA (mean follow-up, 21.5 months) and 21 patients with ESC and helmet therapy (mean follow-up, 23.5 months). The mean aniso-astigmatism was equal; however, the SD was greater for those treated by FOA (P < 0.05). A more severe pattern of strabismus developed in those treated by FOA (P < 0.0001). Those treated by FOA were more likely to have amblyopia (P = 0.0015) and to undergo surgical correction of their strabismus (odds ratio, 6.3:1). CONCLUSIONS: Children with UCS treated with ESC and helmeting had less severe overelevation in adduction, amblyopia, extremes of astigmatism, and less need for strabismus surgery than those treated by FOA. Although the reason for these more favorable outcomes remains uncertain, we speculate that the earlier timing of ESC or differences in the anatomical changes resulting from the two procedures may play a role.
