Low-cost synthetic model for skin flap training

Introduction: The search for learning surgical techniques within the operating room is linked to difficulties, such as reducing teaching time by surgeons and ethical problems. Models have already been developed to facilitate the practice of surgical techniques, however, with high cost, difficult access, and ethical and moral complications. The present work aims to present a synthetic model, unpublished and practical for the training of skin flap techniques, formulated to be easy to reproduce and low cost, allowing its feasibility. Methods: In the model, fabric, sponge for car washing, latex elastic, fine-tipped brush, scalpel, and surgical suture instruments were used. The fabric is fixed by the elastic on the surface of the sponge, simulating skin and subcutaneous. The flap to be made on the surface of the fabric is then drawn. Results: The model created was satisfactory, since it improves the handling of surgical instruments and the learning of the proposed flap technique, besides having demonstrated good elasticity and tensile strength. In medical schools, there is a lack of approach to essential topics in plastic surgery. The importance of low-cost and easy-to-execute models, such as the above, is emphasized to facilitate the learning of students interested in the subject, seeking to fulfill the educational function without breaking ethical principles. Conclusion: The proposed model is an excellent form of training because it presents logistical and instructive benefits, facilitating learning, without causing harm to animals

Low-cost, synthetic model for training and simulation of open and semi-open rhinoplasty

Introduction: Rhinoplasty is indicated for performing aesthetic repairs in the nose, being functional when it also seeks to improve respiratory function. Procedure results are based on improved quality of life and patient satisfaction. It is a complex surgery that requires adequate training. In this sense, several strategies were introduced, such as educational videos, simulations, studies on cadavers and in clinical skills laboratories; however, the basis of training remains the master-apprentice relationship in surgery. Methods: The base materials used in the construction of the model were: hot glue, basin, water, detergent, epoxy putty, spatulas for crafts, nose mold, suture threads, white acetic silicone, disposable cup and spoon and coloring agents. Results: The resulting low-cost model has remarkable similarity with the external appearance and with the cartilages of the nose, allowing easy identification and handling of each structure. Allows good simulation of some steps of the open and semi-open techniques of rhinoplasty. Conclusion: The new synthetic model developed avoids ethical and legal questions that alternative methods such as animals and fresh cadavers raise. Although it requires skill for its manufacture, it has characteristics such as low cost, which favor its dissemination among medical schools. The exposed model can positively impact the learning process of rhinoplasty, revealing itself as an accessible and helpful tool for training in various stages of the technique of this complex surgery
