Teaching parotid surgery to ENT residents in the era of new technologies: an ex-vivo ovine model. J Biol Regul Homeost Agents. 2020 Sep-Oct;34(5 Suppl. 3):119-122. Technology in Medicine Authors: Rinaldi V, Costantino A, De Virgilio A, Spriano G, Alloni R, Moffa A, Casale M Abstract Surgical training has recently assumed a central role in the otolaryngology field, and the necessity to train residents and fellows' skills in a progressive manner has led to an incredible widespread of ex-vivo animal models for several surgical procedures. To report our experience with an ex-vivo ovine model for parotid gland dissection in a training context. A junior resident (PGY-1) and a post-graduate student with no experience in parotid surgery were guided by a skilled surgeon in the parotid gland dissection for each step of the procedure. Three different adult lamb heads were used for this feasibility study. A specific preparation of the model was performed before the training session. Similarity between the ovine model and the human were recorded. The resident and the post-graduate student were able to carry out a complete parotid gland dissection under supervision. The correct identification of surgical landmarks has led to a proper surgical simulation. The facial nerve dissection was adequately performed, and all branches were isolated. Parotid surgery training on an ex-vivo ovine model is useful, easy repeatable, and low cost. The ovine model p...
