Summary
Polyester resin plastination preserves anatomical specimens for education and research. While effective, methods require specialized facilities and training, with ongoing efforts to improve standardization and digital integration.
Area of Science:
- Anatomical Sciences
- Medical Education Technology
- Preservation Techniques
Background:
- Polyester resin plastination is a key technique for anatomical preservation.
- It is particularly valuable in neuroanatomy education and radiological correlation.
- This review covers polyester-based sheet plastination methods (P35, P40, P45).
Purpose of the Study:
- To synthesize principles, technical evolution, and variations of polyester-based sheet plastination.
- To review applications and limitations of P35, P40, and P45 methods.
- To assess the methodological quality of plastination studies using the AQUA tool.
Main Methods:
- Analysis of key documents on polyester sheet plastination techniques.
- Tracing the evolution from P35 to P40 and P45 methods.
- Assessment of methodological quality using the AQUA tool (Objectives, Study Design, Methodology, Descriptive Anatomy, Results Reporting).
Main Results:
- Polyester plastination enhances anatomical understanding and CT/MRI correlation in medical/veterinary education and research.
- AQUA analysis indicated low bias in Objectives and Descriptive Anatomy, but higher risk in Study Design, Methodology, and Results Reporting.
- Methodological rigor improved in publications after 2010, suggesting growing standardization.
Conclusions:
- Polyester sheet plastination is versatile but demands specialized infrastructure, personnel, and environmental control.
- Future directions include protocol standardization, international dissemination, and digital technology integration.
- Progress relies on collaboration, training, and open access to resources.
