Pediatric Frontalis Suspension With Braided Polyester: A Comparison of Two Techniques.

PURPOSE: To demonstrate the benefits of using braided polyester in the management of severe or recurrent ptosis in children and young adults and to compare the efficacy of two surgical techniques. METHODS: Retrospective, non-randomized record review of 30 patients (43 eyelid procedures) affected by congenital or acquired severe ptosis who underwent frontalis suspension with braided polyester from 2008 to 2016. Two surgical techniques were compared: the base-down triangle and the Fox pentagon, both of which were performed using a closed technique. Functional success was defined as clearing of the visual axis. Complications and results were examined. RESULTS: Functional success was obtained in 39 eyes of 43 procedures. Marginal reflex distance increased an average of 2.51 mm with the base-down triangle technique and 1.70 mm with the Fox pentagon technique (P = .05). The vertical palpebral fissure height increased an average of 4.60 mm with the base-down triangle technique and 2.45 mm with the Fox pentagon technique (P < .001). Mean follow-up duration was 38.6 months. Complications included untied suture (n = 2), suture dehiscence (n = 1), cellulitis (n = 2), and granuloma (n = 1). CONCLUSIONS: Braided polyester was found to be a safe, effective, easy-to-handle, and low-cost sling material for frontalis suspension and should be considered for clinical use, especially in developing countries where the cost and availability of other materials represents a significant barrier to treatment. In the authors' experience, the base-down triangle technique appeared superior to the Fox pentagon technique. [J Pediatr Ophthalmol Strabismus. 2018;55(4):229-233.].

Primary treatment of nasolacrimal duct obstruction with balloon catheter dilation in children younger than 4 years of age.

PURPOSE: To report the outcome of nasolacrimal duct balloon catheter dilation as the primary treatment of congenital nasolacrimal duct obstruction (NLDO) in children younger than 4 years of age. METHODS: One hundred two children (151 eyes) ages 12 to <48 months (mean, 23 months) at the time of surgery, who previously had not undergone a nasolacrimal surgical procedure and who presented with at least one of the following clinical signs of NLDO--epiphora, increased tear lake, and/or mucous discharge--were enrolled in a prospective, nonrandomized observational multicenter study (20 sites). All children received balloon catheter dilation of the nasolacrimal system of the affected eye(s). RESULTS: Treatment success was defined as no epiphora, increased tear lake, and/or mucous discharge present at the outcome visit at 1 month after surgery. The proportion of eyes treated successfully was 82% (95% CI: 74%-88%). The dye disappearance test at outcome was normal in 105 (73%), indeterminate in 15 (10%), and abnormal in 23 (16%) of the 143 eyes tested. CONCLUSIONS: In children 12 to <48 months of age, balloon catheter dilation as a primary treatment of NLDO was successful in approximately 80% of cases. Because we did not perform a randomized trial with a comparison group, we were unable to determine how this procedure's success rate compares with that of simple probing or nasolacrimal intubation in this age group.
