Abstract: 

Background: Traditional formalin-fixed cadavers have long been the cornerstone of gross anatomy education. However, formalin fixation induces significant tissue rigidity, alters joint biomechanics, and darkens anatomical structures, limiting its utility for modern surgical simulation and clinical competency-based medical education (CBME). Over the last two decades, advanced cadaveric preservation methods have emerged to bridge the gap between classical anatomy and real-world clinical skills. This systematic review evaluates the educational efficacy, structural fidelity, and biochemical safety of innovative preservation techniques in 21st-century medical curricula.

Methodology: A systematic literature search was conducted across major electronic databases (PubMed, Embase, Scopus, and Cochrane Library) up to January 2026. Studies evaluating advanced preservation techniques—specifically Thiel’s Soft-Fix Method, Larssen Solution, Plastination, and Saturated Salt Solutions (SSS)—in comparison to traditional formalin fixation were included. The primary outcomes assessed were tissue lifelike fidelity, joint flexibility, color preservation, structural durability for repeated use, and hazardous chemical exposure levels.

Results: Data from 42 peer-reviewed studies meeting the strict inclusion criteria were synthesized. The comparative analysis demonstrated distinct curricular advantages for each technique:

• Thiel's Soft-Fix Method: Exhibited superior joint flexibility and lifelike tissue turgor, making it the most optimal model for advanced surgical training, laparoscopic simulation, and ultrasound-guided procedures.

• Plastination: Provided highly durable, dry, non-toxic specimens that excelled in undergraduate cross-sectional anatomy teaching, though unsuitable for active surgical manipulation.

• Saturated Salt Solutions (SSS): Offered a low-cost, low-formalin alternative with excellent microbial control and well-preserved muscle color, rendering it highly viable for resource-limited medical colleges.

• Formalin Safety: Advanced techniques universally demonstrated a significant reduction in indoor formaldehyde vapor levels, aligning with global occupational safety standards.

Conclusion: Advanced cadaveric preservation techniques are essential for transforming traditional dissection labs into modern surgical skills centers. While Thiel-embalmed specimens are invaluable for clinical residency training and procedural mastery, Plastination and SSS offer scalable, safe, and highly pedagogical tools for undergraduate medical curricula. Implementing a hybrid model that integrates these innovative techniques ensures compliance with modern CBME guidelines, optimizing both student learning outcomes and workplace safety in the Department of Anatomy.
