At the Faculty of Veterinary Medicine, Cairo University, there is an increasing number of students but a limited availability of animal cadavers used for dissection, and student exposure to formalin is a known hazard. In order to address these challenges, a new method for tissue preservation was developed, the "Elnady Technique." This method is a modified form of plastination, where the chemicals used are not patented, are inexpensive and locally available, and the process is performed at room temperature. The produced specimens are realistic, durable, have no offensive odor, and are dry, soft and flexible. They can be used to replace the use of animals killed for teaching basic anatomy, embryology, pathology, parasitology and forensic medicine. They have great potential to support training in clinical skills and surgery, including for clinical examination, endoscopy, surgical sutures, and obstetrics simulation.

Endoscopy of the upper respiratory tract (URT) is one of the minimally invasive techniques used for diagnosis and treatment of diseases in horses. Training in the use of an endoscope follows an apprenticeship approach, with extensive practice needed to help achieve effective skills acquisition. The use of live animals for training presents the risk of injury to both the animal and the trainee. The increased number of students and practitioners, a shortage of facilities, and limited time available from expert clinicians add more challenges to the training process. In this work, we focused on the development of a preserved head and neck model that can be used as an effective training tool for training novices on the basics of upper respiratory endoscopy. The aim of the training is to become familiar with handling the endoscope and identification of the endoscopic depictions of normal anatomical structures encountered in the upper respiratory tract. Using the model, anatomical structures were clearly visible, recognized by their shape, architecture and topographical location. The model solved many of the aforementioned practical challenges, and has great potential as a replacement alternative to the use of live animals. There are opportunities for the application of such models intraining other clinical skills and for a variety of species.
