E12 sheet plastination: Techniques and applications

Plastination is an anatomical technique that consists of replacing the liquids and fat of specimens by reactive polymers through forced impregnation in a vacuum. These are then polymerized to achieve the final result. E12 sheet plastination involves epoxy resin impregnation of thin (2-4 mm) and ultra-thin (<2 mm) tissue sheets, producing dry, transparent, odorless, non-toxic and long-lasting sheets. E12 sheet plastination techniques were reviewed using MEDLINE, EMBASE and SciELO databases, and manual searches. After searching, 616 records were found using the online and manual searches (MEDLINE, n: 207; EMBASE, n: 346; SciELO, n: 44; Manual search: 23). Finally, 96 records were included in this review (after duplicates and articles unrelated to the subject were excluded). The aim of this work was to review the E12 sheet plastination technique, searching for articles concerning views of it, identifying the different variants implemented by researchers since its creation by Gunther von Hagens, and to identify its applications from teaching and research in anatomy to morphological sciences.

“…). The results are dry, transparent, odor‐free, and durable slices (Sora et al , , , , ; Qiu et al ; Sora and Cook, ; Marks et al, ; Hermans et al, ; Diao et al, ). The method prevents decomposition of the sample and encrusts it in transparent epoxy to create an optical interface of high tissue quality (Marks et al, ).…”

The dumbbell-shaped adipose zone is likely communicated with a similar fine trabecular network at the posteroinferior aspect of the pituitary gland, medial to the internal carotid artery [10].…”

“…Three weak points of the sinus wall were identified for tumor invasion [5]. Although anatomy of the boundaries and neurovascular structures in the cavernous sinus has been extensively studied [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], few studies have focused on the fibrous supporting matrix within the sinus [3], [4], [5], [10]. Understanding of configuration and localization of fibrous trabeculae and adipose tissue in the cavernous sinus may be valuable for better understanding of tissue patterning in the cranial base and better evaluation of intracavernous disorders, e.g.…”

“…Although histologic examination may be able to overcome the problem, the application of such method is greatly limited by the size of sample areas, alteration of tissue architecture during decalcification, and difficulty in tracing the origin of a fibrous structure. The newly developed anatomy technology, sheet plastination, not only preserves in situ positions of the cranial bones, meninges, nerves, vessels and loose fibrous tissue without decalcification but also allows these structures to be examined at both the macroscopic and microscopic levels [10], [19], [20]. The plastination process results in collagen fibers and neurofilaments being endogenously autofluorescent [20].…”

ObjectiveThree-dimensional anatomical appreciation of the matrix of the cavernous sinus is one of the crucial necessities for a better understanding of tissue patterning and various disorders in the sinus. The purpose of this study was to reveal configuration of fibrous and adipose components in the cavernous sinus and their relationship with the cranial nerves and vessels in the sinus and meningeal sinus wall.Materials and MethodsNineteen cadavers (8 females and 11 males; age range, 54–89 years; mean age, 75 years) were prepared as transverse (6 sets), coronal (3 sets) and sagittal (10 sets) plastinated sections that were examined at both macroscopic and microscopic levels.ResultsTwo types of the web-like fibrous networks were identified and localized in the cavernous sinus. A dural trabecular network constituted a skeleton-frame in the sinus and contributed to the sleeves of intracavernous cranial nerves III, IV, V1, V2 and VI. A fine trabecular network, or adipose tissue, was the matrix of the sinus and was mainly distributed along the medial side of the intracavernous cranial nerves, forming a dumbbell-shaped adipose zone in the sinus.ConclusionsThis study revealed the nature, fine architecture and localization of the fine and dural trabecular networks in the cavernous sinus and their relationship with intracavernous cranial nerves and vessels. The results may be valuable for better understanding of tissue patterning in the cranial base and better evaluation of intracavernous disorders, e.g. the growth direction and extent of intracavernous tumors.

Is There an Identifiable Intact Medial Wall of the Cavernous Sinus? Macro- and Microscopic Anatomical Study Using Sheet Plastination

Abstract: The medial wall of the cavernous sinus consists of both the meningeal dura and weblike loose fibrous network, which are located at the anterosuperior and posteroinferior aspects, respectively.
