Summary
3D printed models of costal cartilage and auricular frameworks effectively enhance plastic surgery trainees' understanding and confidence in ear reconstruction techniques. This innovative approach significantly improves learning outcomes for this complex surgical procedure.
Area of Science:
- Plastic Surgery
- Medical Education
- 3D Printing Technology
Background:
- Ear reconstruction is a complex surgical procedure requiring significant experience and planning.
- Traditional training methods may not adequately convey the intricate 3D structure of auricular anatomy.
- There is a need for improved, hands-on training tools for auricular reconstruction.
Purpose of the Study:
- To validate the use of carvable 3D printed rib models and auricular frameworks for teaching auricular reconstruction.
- To assess the impact of these 3D printed models on trainees' confidence and comprehension.
- To evaluate the suitability of 3D printed models as adjuncts in surgical planning and education.
Main Methods:
- 3D printing of simulated costal cartilages (ribs 6-9) and auricular frameworks using FormLabs Form3 and Ultimaker 3 printers.
- Creation of carvable silicone-cornstarch costal cartilage models.
- Workshop involving 12 plastic surgery trainees using the 3D printed models for simulated auricular reconstruction, with pre- and post-training assessments.
Main Results:
- Significant improvements in understanding auricular framework components (p < 0.0001) and confidence in handling costal cartilage (p < 0.0001).
- Highly significant improvements in comprehension of ear reconstruction approach (p = 0.006) and locating subunits (p = 0.003).
- 100% of participants reported that the 3D printed aids directly enhanced their learning experience.
Conclusions:
- 3D printed costal cartilage models provide a valuable tool for simulating surgical material.
- 3D printed auricular frameworks aid in comprehending and planning complex ear reconstructions.
- These 3D printed models significantly enhance the educational value and practical skills acquisition for auricular reconstruction training.
