1 · What the graph read from it

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.

2 · The registry

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

objectiveTo evaluate postoperative enophthalmos and ocular motility following Double Silicone Procedure (DSP), contextualized against an earlier Silicone Balloon Fixation (SBF) cohort from a time-separated single-center experience.

methodsWe conducted a single-center retrospective case series (April 2000 - December 2024) across a technique transition (SBF before April 2014; DSP thereafter). Primary outcomes were patient-reported enophthalmos (graded 0-4) and postoperative ocular motility (HAR%). Between-era differences were descriptively analyzed using Hodges-Lehmann estimates with 95% Confidence Intervals (95% CIs).

resultsThirty patients met the inclusion criteria (DSP, n = 10; SBF, n = 20). The median postoperative enophthalmos score was 0 (Interquartile Range [IQR] 0-0) in the DSP group (n = 10) and 1 (IQR 0-1) in the SBF group (n = 13) (Hodges-Lehmann Δ = -1.0; 95% CI -1.0 to 0.0; p = 0.008). Among DSP patients with postoperative Hertel exophthalmometry measurements (n = 8), no patient exhibited clinically perceptible enophthalmos (>2 mm); the median Hertel exophthalmometry difference was -1.0 mm (IQR -1.0 to 0.0). Postoperative HAR% was 92.1% (IQR 86.0-100.0) after DSP and 88.4% (IQR 80.4-97.0) after SBF (p = 0.397). No optic nerve injuries, infections, or implant-related complications were observed in either group.

conclusionIn this single-center experience across a surgical technique transition, DSP demonstrated favorable postoperative outcomes, with reduced enophthalmos and preserved ocular motility. Although earlier cases served as a historical reference, these exploratory findings support DSP as a safe and practical option for complex inferomedial orbital wall fractures. LEVEL OF EVIDENCE: 4:
