Bridging the Gap in Rhinoplasty Training: The Effectiveness of 3D Printed Models in Surgical Education.
Article in Aesthetic surgery journal, 2025. 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
backgroundRhinoplasty is a common facial plastic surgery procedure for both functional and aesthetic indications. The use of 3-dimensional (3D) models has been reported as a potential method for providing hands-on training for learning rhinoplasty without jeopardizing patient care.
objectivesThe objective of this study was to develop and validate a novel model for rhinoplasty training.
methodsThe rhinoplasty models were designed and produced with proprietary 3D printing technology. Face and content validity were assessed during a rhinoplasty course involving 53 surgeons. Criterion validity was evaluated in a training session with 20 surgical residents, measuring improvements in surgical skills after practice with the 3D models, with an objective structured assessment of technical skills (OSAT).
resultsAll surgeons (n = 53, 100%) stated that the rhinoplasty model aided in their learning and development. In all, 91% (n = 48) of surgeons rated the realism of the model as excellent or very good in comparison to cadaveric specimens. Assessment of criterion validity showed a statistically significant improvement in OSAT scores among surgical residents, increasing from a baseline of 11.7/40 (SD ± 1.80) to 21.6/40 (SD ± 1.79) post session (P < .0001).
conclusionsThe 3D rhinoplasty models showed good content, face, and criterion validity, objectively improving residents' surgical performance. Rhinoplasty 3D models may serve as a precadaveric training adjunct, equipping trainees with fundamental skills before cadaveric dissection, or as a primary training modality in countries with limited cadaver access. Therefore the models offer an innovative approach to training the next generation of rhinoplasty surgeons.
