Puncture points related to the tragal-lateral canthus line in conventional temporomandibular joint arthrocentesis: are they accurate? A cadaver study.
Article in Oral and maxillofacial surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
purposeTo evaluate the technical success of conventional TMJ arthrocentesis in cadavers, using the tragal-lateral canthus line as an anatomical reference for the puncture points.
methodsTen formalin-treated and 8 fresh cadavers were submitted to the arthrocentesis. A point located 10 mm anteriorly and 2 mm inferiorly to the beginning of the tragal-lateral canthus line (A) and another point 20 mm anteriorly and 10 mm inferiorly (B) were demarked on the cadavers' skin. Following, 1 mL of methylene blue solution was injected through the needle at point A, and then another needle was placed at point B. Saline solution was injected through the first needle, identifying a free flow of bluish solution.
resultsConcerning the formalin-treated cadavers, TMJ arthrocentesis was not successfully performed in any case (0%). In the fresh cadavers, the procedure was properly conducted bilaterally in only one case (12.5%) and unilaterally in 3 cases (37.5%), 2 on the left side (25.0%) and one on the right (12.5%).
conclusionThe traditional points related to the tragal-lateral canthus line seemed not to be accurate references for the insertion of the needles in conventional TMJ arthrocentesis when 1 mL of solution is used initially and the maximum mouth opening is not achieved.
