Rapid reduction of temporomandibular joint dislocation with a modified and optimized patient-guided technique: a retrospective case series.

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
objectiveTo report a modified and optimized patient-guided maneuver for the rapid and physiological reduction of temporomandibular joint (TMJ) dislocation.
methodsA retrospective case series was conducted at a single Emergency Department from January 2017 to December 2022. The study evaluated 83 consecutive patients with acute TMJ dislocation treated with a modified and optimized patient-guided technique. The maneuver follows a two-step sequence: Step 1 involves concurrent mouth opening and head extension; Step 2 involves mouth closing and head flexion while the clinician applies gentle, sustained downward traction. Reduction time was recorded by an independent observer.
resultsThe overall success rate for achieving anatomical goals was 100%. Specifically, for simple dislocations (n = 81), a 100% reduction success rate was achieved within a mean time of 150 s. For dislocations complicated by condylar fractures (n = 2), the maneuver was 100% successful in achieving temporary palliative alignment, which served as a crucial bridge to definitive surgical intervention. No iatrogenic injuries or complications were observed in either group.
conclusionThis patient-guided approach utilizes active patient movement to facilitate reduction with minimal force. It appears to reduce iatrogenic risk and improve patient tolerance compared to traditional high-force maneuvers. While 100% success was observed in this series, the results are limited by the single-center, single-operator design. Further multi-center prospective trials are necessary to validate these findings and assess long-term outcomes. CLINICAL SIGNIFICANCE: The patient-guided technique provides a controlled, less traumatic alternative for TMJ reduction, potentially reducing the need for anesthesia and improving the overall patient experience in emergency settings.
