Unexpected Botulinum Toxin Effect on Neck Rejuvenation After a Jawline Lifting Procedure: A Case Report.
Article in Cureus, 2026. 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
Aging of the platysma muscle significantly contributes to the loss of mandibular contour definition and the vertical platysmal bands aspect, negatively affecting the neck appearance. Botulinum toxin has been widely used for facial rejuvenation, including jawline lifting. We described the case of a 51-year-old woman who underwent lower-face neuromodulator treatment with prabotulinumtoxinA (Nabota®, Daewoong, Seoul, South Korea). Nine superficial injection points per hemiface were applied along the mandibular and submandibular regions. Three-dimensional stereophotogrammetry (LifeViz® Mini, QuantifiCare, Biot, France) was performed before treatment and 15 days post-procedure to quantify the soft tissue displacement and volumetric changes. Clinical evaluation demonstrated a visible reduction of platysmal bands during muscle activation and improved mandibular contour definition. The 3D analysis revealed a volume reduction of 2.4 mL in the right upper neck region and 6.32 mL along the lateral cervical area. No adverse events were reported. These findings suggest a distal functional effect on the platysma muscle, highlighting a potentially safer and lower-dose approach for neck rejuvenation. Further studies are required to validate these results.
