“…Làszlò et al ( 48 ) highlighted the teaching of fibreoptically guided intubation of the trachea by the use of Thiel's cadaver. Tomlinson et al ( 49 ) affirmed that both the “Thiel and Crosado cadavers offered lifelike simulation of pedicle screw insertion, with each having advantages depending on whether the focus is on soft tissue approach or technical aspects of bony screw insertion in the spinal surgery.” Eljamel et al ( 50 ) evaluated “the use of Thiel cadaveric model to practice MRI-guided deep brain stimulation (DBS) implantation and high-frequency MRI-guided high frequency focused ultrasound (FUS) in the human brain.” Lone et al ( 51 ) showed that Thiel-embalmed cadavers provided a useful tool for simulation of a local anesthetic injection technique. Porzionato et al ( 52 ) demonstrated that Thiel cadavers are suitable for laparoscopy and also for procedures of the Natural Orifice Transluminal Endoscopic Surgery (NOTES), whose development and learning are usually realized with the swine models and fresh frozen cadavers.…”

Forensic Implications of Anatomical Education and Surgical Training With Cadavers

Anatomical education and surgical training with cadavers are usually considered an appropriate method of teaching, above all for all surgeons at various levels. Indeed, in such a way they put into practice and exercise a procedure before performing it live, reducing the learning curve in a safe environment and the risks for the patients. Really, up to now it is not clear if the nonuse of the cadavers for anatomical education and surgical training can have also forensic implications. A substantial literature research was used for this review, based on PubMed and Web of Science database. From this review, it is clear that the cadaveric training could be considered mandatory, both for surgeons and for medical students, leading to a series of questions with forensic implications. Indeed, there are many evidences that a cadaver lab can improve the learning curve of a surgeon, above all in the first part of the curve, in which frequent and severe complications are possible. Consequently, a medical responsibility for residents and surgeons which perform a procedure without adequate training could be advised, but also for hospital, that has to guarantee a sufficient training for its surgeons and other specialists through cadaver labs. Surely, this type of training could help to improve the practical skills of surgeons working in small hospitals, where some procedures are rare. Cadaver studies can permit a better evaluation of safety and efficacy of new surgical devices by surgeons, avoiding using patients as ≪guinea pigs≫. Indeed, a legal responsibility for a surgeon and other specialists could exist in the use of a new device without an apparent regulatory oversight. For a good medical practice, the surgeons should communicate to the patient the unsure procedural risks, making sure the patients' full understanding about the novelty of the procedure and that they have used this technique on few, if any, patients before. Cadaver training could represent a shortcut in the standard training process, increasing both the surgeon learning curve and patient confidence. Forensic clinical anatomy can supervise and support all these aspects of the formation and of the use of cadaver training.

“…In our study, non-fixed cadavers were used, the storage of which was carried out by cooling. The obtained results of the effectiveness of the teaching methodology are confirmed by Lone M. et al, 2017, that cadaveric material, including fixed, thiel-embalmed cadavers, may provide an ideal tool for teaching the injection technique of local anesthesia [ 25 ]. Moreover, per Kennel L. et al, 2018, a group of students felt more confident about recognizing anatomy in the living individual, found it easier to identify and dissect anatomical structures, and indicated more active exploration of functional anatomy due to the retained flexibility of the cadaver [ 26 ].…”

Cross-Sectional Study on the Comparative Assessment of Mandibular Anesthesia (Inferior Alveolar Nerve Blockage) Manual Skills Shaping among Dentists on Plastic and Biomaterial Models

Background: Providing regional anesthesia skills shaping remains relevant nowadays. A number of studies show that dentists have difficulties with these working independently. The study aim is the comparative analysis of the results of mandibular anesthesia (IANB) manual-skills shaping among dentists on plastic models and cadavers. Methods: In total, 999 participants were training in the skills of mandibular anesthesia from 2017 to 2021. The participants were divided in a random way into two groups: 700 participants were trained on plastic models, and 299 were trained on the cadaver material. After a lecture on the clinical and anatomical guidelines for IANB, a demonstration of the technique was provided, with subsequent testing of the injection technique. Satisfaction with the aspects of the training was assessed using the Likert scale. Results: the analysis of average values showed that participants from the group in which the manual skills were practiced on cadavers were more satisfied with the main aspects of the training, according to the sum of the main criteria of the modified scale. Conclusions: The important advantages of cadaver educational technology are that the sensations of tissue resistance are identical to natural ones, the individuality of each object, and the possibility of the visual study of the anesthesia technique, by dissection of the needle course and the location of the anesthetic depot.

“…Due to the very limited flexibility of formalin-embalmed cadavers, dental anatomy teaching has been limited by the availability of appropriate materials demonstrating features of the oral cavity. When materials are available, the texture and appearance of the living tissue of the oral cavity are not preserved (Lone et al, 2017). Although formalin-embedded specimens can be used for the examination of oral anatomy, they are considered inappropriate for realistic surgical training.…”

The purpose of this study was to assess the usefulness of saturated salt solution‐embalmed cadavers for oral surgical skills training related to bone graft harvesting. Two half‐day surgical skills training workshops were held at the Tokyo Medical University utilizing eight cadavers embalmed with the saturated salt solution. A total of 22 participants including oral surgeons, residents, and dentists attended the workshop. Surgical training consisted of six procedures related to intraoral and extraoral bone harvesting. The participants were surveyed to assess self‐confidence levels for each surgical procedure before and after completion of each workshop. The Wilcoxon signed‐rank test was used to compare the differences between each median score before and after the workshop. There were statistically significant increases in the self‐assessed confidence scores in bone harvesting procedures for the zygomatic bone (P = 0.003), maxillary tuberosity (P = 0.002), and other sites (P < 0.001). The anatomical features of saturated salt solution‐embalmed cadavers were also examined. The textures of the oral mucosa and skin were similar to those of living individuals. The structure of bone tissues was well‐preserved and the hardness was realistic. Consequently, all procedures were performed with sufficient realism. The saturated salt solution method has a relatively low cost of preparation and storage, and almost no odor. The authors suggest that saturated salt solution‐embalmed cadavers could provide a new model for oral surgical skills training in bone harvesting.
