Maxillary advancement and soft tissue response in Le Fort I osteotomy.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundTo evaluate the correlation between the amount of maxillary advancement and soft tissue changes, and to assess the long-term skeletal stability in patients who underwent Le Fort I osteotomy as part of bimaxillary orthognathic surgery.
methodsThis retrospective cohort study included 25 patients with skeletal Class III malocclusion who underwent bimaxillary orthognathic surgery. Cephalometric measurements were obtained at three timepoints: before orthodontic treatment (T0), after postsurgical orthodontic treatment (T1), and 1–3 years post-treatment (T2), with an average follow-up period of 2.1 years. Horizontal and vertical skeletal and soft tissue changes were assessed using standardized lateral cephalometric radiographs. Repeated measures ANOVA and Pearson correlation coefficients were used for statistical analysis.
resultsThe mean planned maxillary advancement was 5.48 mm, while the actual advancement achieved was 5.32 mm (p > 0.05). A statistically significant correlation was found between maxillary advancement (A–VR1) and both the change in SNA angle (r = 0.481; p < 0.05) and upper lip advancement (r = 0.319; p < 0.05). The upper lip followed approximately 83% of the maxillary movement. The nasal tip exhibited an average elevation of 1.27 mm, corresponding to a skeletal-to-soft tissue movement ratio of about 5:1. The mean skeletal relapse at Point A was 0.44 mm, representing 8.2% of the total advancement, and this difference was not statistically significant.
conclusionsMaxillary advancement performed through Le Fort I osteotomy demonstrates high precision and long-term skeletal and soft tissue stability. These findings support that Le Fort I osteotomy is a reliable, effective, and predictable surgical technique for achieving stable maxillary advancement and harmonious soft tissue adaptation over the long term.
