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 presented in this study has similarities in size, structure, and tissue consistence to the human parotid, making it an ideal model for residents to simulate parotid surgery.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
