Frontalis sling surgery - pediatric versus adult population: characteristics and outcomes.
Article in BMC ophthalmology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeFrontalis sling surgery is a common method for ptosis correction for both pediatric and adult populations. This study aims to compare the characteristics and outcomes of this surgery in these two populations.
methodsA retrospective cohort study. Patients who underwent frontalis sling surgery between the years 2009 and 2024, with complete medical chart data, and had at least a one-month follow-up period were included. Age, gender, ptosis type, type of sling, complications, and re-surgery were analyzed.
resultsA total of 62 patients were included, with 41 patients in the pediatric group and 21 patients in the adult group. The mean age was 4.7 ± 5.0 and 46.04 ± 18.33 years old in the pediatric and adult groups, respectively. The most common etiology of ptosis in the pediatric group was simple congenital (70%), while the most common etiology in the adult group was myogenic ptosis due to a systemic condition (47%) (p < 0.001). Baseline pre-operative MRD1 (marginal reflex distance 1) was lower in the adult group compared to the pediatric ( -0.37 ± 1.21 mm vs. 0.36 ± 0.65 mm respectively (t-test, p = 0.04)). However, the mean change in MRD1 (pre-operative to postoperative) was not significantly different for both groups (t-test, p = 0.5). A higher rate of sling extrusion was observed among the adult group (0% of pediatrics vs. 14% of adults, chi-square, p = 0.013). A higher number of previous sling surgeries were found to be positively correlated (r = 0.672) with overall postoperative complications (Pearson correlation. p = 0.006).
conclusionFrontalis sling surgery varies between adult and pediatric patients regarding etiology, preoperative findings, surgical approach, and complications. Adults experienced higher rates of complications such as sling extrusion and dry eye. Moreover, an increased number of previous sling surgeries was associated with a rise in postoperative complications such as suture dehiscence, extrusion, and granuloma formation. Consequently, frontalis sling procedures should be regarded as a last resort for ptosis correction in adults due to the elevated risk of complications.
