Abstract
Purpose
To compare the surgical outcomes of tarsofrontalis sling surgery using silicon rod versus supramaximal levator resection in patients of unilateral congenital ptosis with poor levator function (≤ 4 mm).
Materials and Methods
This randomized control study was conducted over a period of 18 months. 44 patients were enrolled in the study group. The study population was randomly divided into two groups (22 in each group). In Group A, congenital ptosis was treated with tarsofrontalis sling surgery using silicon rod and supramaximal levator resection was done in the group B. Follow-up examination was done at postoperative day 1, one week, 1 month, 6 months and 12 months. Surgical outcome measures were change in marginal reflex distance-1 (MRD 1), vertical palpebral fissure height (VPFH) and inter-eyelid difference of margin reflex distance 1 and complications in two groups.
Results
The mean age of patients in group A was 7.25 ± 6.10 years ranging from 1–18 years and mean age of patients in group B was 5.64 ± 2.44 years ranging from 3 to 11 years. Good surgical outcome was obtained in 73–77% of both groups. MRD1and VPFH increased significantly after surgery from baseline in both the groups (p value < 0.001). Inter-eyelid MRD 1 difference also improved significantly in both groups following ptosis surgery.
Conclusion
Both supramaximal levator resection and tarsofrontalis sling surgery are equally effective in cases of unilateral ptosis patients with poor levator function and should be part of the surgical armamentarium for treating congenital ptosis.
