Evaluating educational effectiveness of three-dimensional (3D)-printed training models and custom-made fibula model for osteotomy and flap inset training in head and neck reconstruction.
Article in Maxillofacial plastic and reconstructive surgery, 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
backgroundReconstructive surgery following head and neck cancer resection is inherently complex and technically demanding. Procedures such as osteotomy and flap inset involve a steep learning curve, yet opportunities for hands-on training are increasingly limited. Physical simulation using cost-effective, anatomically realistic models offers a promising solution. This study aimed to evaluate the educational value of 3D-printed training models and custom-made fibula models in enhancing surgical skills, supported by structured assessments and feedback.
methodsA hands-on workshop was conducted for 30 plastic surgery residents utilizing in-house 3D-printed models, created via fused deposition modeling (FDM), and acrylic-based fibula models. Participants performed simulated osteotomies and flap insets. Their performance was assessed using the 4-point Zwisch scale by two independent, blinded consultants. Additionally, a 6-item questionnaire was administered to capture self-reported improvements in anatomical understanding, surgical technique, and procedural planning. Pre- and post-training questionnaire scores were compared using Wilcoxon signed-rank test.
resultsPost-training, the average questionnaire scores significantly improved from 12.03 ± 2.20 to 20.30 ± 1.56 (p < 0.01). The greatest improvement was noted in the participants' comprehension of surgical planning. Zwisch scale evaluations demonstrated a clear progression toward greater technical independence. Participants also expressed high satisfaction with the anatomical realism, durability, and affordability of the training models.
conclusionLow-cost 3D-printed training models and custom-made fibula models represent an effective and reproducible training tool for developing technical skills in head and neck reconstructive surgery. Their ease of fabrication, affordability, and anatomical accuracy make them particularly valuable in resource-limited settings. These models offer significant educational utility and warrant integration into structured surgical training curriculum.
