A plastic surgery approach to Meige syndrome: Botulinum toxin for rebalancing facial dystonia and aesthetics - A case report.
Article in JPRAS open, 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
Meige syndrome is a rare segmental dystonia characterized by blepharospasm and oromandibular dystonia, often leading to significant functional and aesthetic impairment. This report details a 59-year-old female patient with a 16-year history whose symptoms were refractory to prior drug therapies. An individualized botulinum toxin type A (BTX-A) injection protocol was devised based on detailed facial muscle mapping and plastic surgery principles of muscle balance. Following treatment, the patient showed marked improvement in facial spasms within 1 week, with resolution of nocturnal headaches and notable correction of aesthetic concerns arising from dystonia, including facial asymmetry and the involuntary "gummy smile". The gingival exposure during dystonic contraction was reduced from >4 mm (classified as severe gingival smile) to 1 mm. Social and eating functions were restored. This case suggests that a BTX-A treatment strategy guided by plastic surgery principles, which addresses both functional symptoms and aesthetic disharmony, may provide an effective and safe office-based treatment option for Meige syndrome. Further studies with larger cohorts are warranted to validate this protocol.
