Abstract
AIM: The aim of this study was to assess the efficacy of frontalis suspension using 4-0 prolene sutures for paediatric ptosis with poor levator function. PATIENTS AND METHODS: A retrospective chart review was performed on children who underwent 4-0 prolene frontalis suspension from 2000 to 2008 with a minimum of 6 months' follow-up. Functional success was defined when three criteria were met: (a) satisfactory lid height (defined as margin-to-reflex distance ≥3 mm with minimal frontalis muscle tone); (b) satisfactory lid symmetry (≤2 mm asymmetry in margin-to-reflex distance); and (c) satisfactory cosmesis. Recurrence was defined by a drop in lid height of ≥3 mm from the initial post-operative level. RESULTS: A total of 23 patients (30 eyelids) were included. The mean follow-up duration was 28.7 months (range 6.3 to 100 months). The functional success rate was 74% (17/23 patients). Ptosis recurred in 22% (5/23) of patients. Only one patient (4%) developed a complication: a case of minor wound infection. CONCLUSIONS: In paediatric ptosis with poor levator function, prolene frontalis suspension has good efficacy and an excellent safety profile. The results of prolene frontalis suspension are comparable to those of other non-autogenous materials.
