Surgical Mechanism of Suspension of the Eyelid to the Check Ligament of the Superior Fornix for Blepharoptosis: An Anatomical Study.

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
Suspension of the eyelid to the check ligament of the superior fornix for blepharoptosis correction was first reported by Holmström in 2002, yet its exact surgical mechanism remains controversial, with core debates focusing on whether the suspension force originates from static or dynamic sources. In this study, twenty eyes from 10 fresh Chinese adult cadavers were used to establish the blepharoptosis models and simulate the suspension surgery. We observed and measured the eyelid lift heights (ELHs) under three different conditions (physiological condition, ptosis model, after simulated surgery) following manual posterior traction of the levator palpebrae superioris or superior rectus muscle. Under the above conditions, the results from pulling the rectus were 2.58 ± 1.03 mm, 1.90 ± 0.84 mm, and 3.75 ± 1.10 mm, and from pulling the levator were 7.95 ± 1.10 mm, 2.13 ± 0.80 mm, and 7.78 ± 1.37 mm. Notably, the initial positions of the eyelids were raised by 1.93 ± 0.90 mm after the simulated surgery. The ELHs could be increased by pulling these muscles, respectively, but the ELH was obviously higher by pulling the levator than the rectus. We speculated that the postoperative driving force of the eyelid lift behind the suspension surgery comprised static suspension force from the check ligament and dynamic contraction force from the levator and rectus together and levator seems to play more important role. Based on this synergistic mechanism, we propose a hypothesis-generating clinical decision-making algorithm tailored to preoperative levator function levels.No Level Assigned This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.
