Plastination was a game-changing invention for macroscopic anatomical preparation. The method yielded dry, odourless, tangible and durable specimens which allowed new exhibition and teaching set-ups and paved the way for sophisticated preparations and spectacular positioning of specimens. Despite the impact of the new method, there have been similar techniques in place before. Exsiccation techniques, polymer embeddings and specimen impregnation with hardening substances were earlier methods which already included the main concepts that were later combined and refined in plastination. S10 silicone plastination, the technique most commonly known and applied, was followed by plastination methods suitable for research and sectional anatomy teaching. Numerous variations of sheet plastination techniques allow research applications and new ways of presenting topographic relations and mesoscopic insights. Besides the development of plastination techniques in sensu stricto, related techniques had a renaissance with new applications and developments, including corrosion casting and diaphonization methods. This brief review shall provide a historical context of plastination including some anecdotal spotlights on the ideas and innovations that lead to nowadays plastination techniques.

Fuchs' endothelial corneal dystrophy (FECD) is a common sight-threatening condition characterised by pathological changes in the posterior cornea. Here we report observations by light, transmission and volume scanning electron microscopy on changes in the endothelium and matrix associated with the characteristic deformations of Descemet's membrane, termed guttae. Specimens were archived full-thickness human corneal tissue, removed during graft surgery, that had been fixed, stained and embedded by conventional processing methods for examination by transmission electron microscopy more than 40-years previously.

Background: Plastination preserves biological specimens for long-term and geometric morphometry analyzes shape differences with advanced statistical methods. This study primarily aimed to statistically quantify shrinkage in brain sections following plastination. The secondary goal was to present the shrinkage occurring in both tissues and cavities of specific anatomical structures using geometric morphometry.

Background And Objective: Neuroanatomy is both terrifying to learn and problematic to teach, and the different methods of neuroanatomical education have their own strengths and weaknesses. In this cross-sectional study, we evaluated the perception of undergraduate medical students towards the combined use of plastinated and formalin-preserved brain specimen in their neuroanatomy course.
Methods: A bridging program was designed for students whose medical education was interrupted by the COVID-19 pandemic in order to reinforce the knowledge and understanding of anatomy that they acquired in a virtual environment.

Background And Objective: The pandemic has forced medical education to adopt online and hybrid set-ups, and this has greatly changed the way human anatomy is taught. Course-required knowledge can be accessed using raw references like original publications, collected reviews such as those found in books, as well as in shorter versions like summaries, and in online or electronic applications or software. With readily accessible online physical materials and human resources in anatomy, the value of learning by seeking out verifiable information to answer a real time query may change the current method of teaching and assessment of outcome-based learning in a heavy-recall subject such as human anatomy.

Objective: An understanding of the complex nomenclature and 3D spatial relations between the cortical and white matter components of the retrocommissural portion of the hippocampal formation is essential for a successful outcome when performing surgery in the mediobasal temporal region. The goal of this study was to clarify the nomenclature related to the retrocommissural portion of the hippocampal formation and to provide a detailed description of its topography and inner structure from a relevant surgical perspective. This description can serve as an anatomical reference for approaching lesions in the mediobasal temporal region.
