“…The ovine sinus simulator utilises a cadaveric sheep's head whose sinus coniguration has some similarities to human anatomy, including the lateral position of the maxillary sinuses, posterosuperior position of the skull base and midline of the position of the septum. The sheep's head, however, is longer, lacks a sphenoid sinus and has poorly aerated ethmoidal cells rendering ethmoidectomy unrealistic [27].…”

“…Nonetheless trainees do consider the experience of training on cadavers to be highly valuable [15]. The sheep's head model as a sinus simulator for the purpose of ESS training has undergone face and construct validation [27,45]. Awad et al suggest that it used as a step in the simulation ladder, prior to in-vivo practice, as it represents an opportunity to focus on basic endoscopic rhinological procedures in conjunction with training on VR and cadaveric models.…”

Surgical simulation is an efective tool used to teach many of the fundamental skills required to be a surgeon. Simulation-based education with directed practice in surgical training allows repeated practice in an environment to learn surgical skills, which do not cause harm to patients. There are several simulators developed for endoscopic sinus surgery training. Some simulators have undergone validation studies with regard to developing skills necessary to perform endoscopic sinus surgery. This book chapter will review the currently available sinus surgery simulators that have undergone validation and evaluate their potential role in surgical training.

“…A variety of different simulation techniques has been adopted, including the use of cadaveric dissection, high‐fidelity animal models, virtual‐reality simulators, and synthetic models, with all simulation methods demonstrating significant improvement in the surgical learning curve . The use of animal models in ear, nose, and throat simulation is widely established in rhinology, facial plastics, and laryngology, due to their low cost and high fidelity, as demonstrated in face and content validity studies . These techniques adopted in other subspecialties could be applied to advanced airway surgery to generate a suitable model for LTR.…”

Therefore, the aim of this study was to perform a systematic review of the literature to identify the suitability of different commercially available animal models used to simulate laryngotracheal reconstruction.…”

Objectives Review of the literature to identify practical, high‐fidelity, commercially available animal models for simulation training and surgical skills maintenance in laryngotracheal reconstruction (LTR). Methods A systematic review of PubMed and Embase databases was conducted independently by two authors, according to Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. Search terms included “laryngotracheal reconstruction,” “laryngotracheoplasty,” “pig and larynx,” “sheep and larynx,” and “rabbit and larynx.” Articles were then assessed, identifying model cost and availability, model validation, feasibility as a training tool, and verisimilitude to pediatric LTR. Results In total, 79 articles were considered suitable for inclusion in the study, incorporating both in vitro and in vivo models. Models utilized included rabbit (n = 69), pig (n = 7), sheep (n = 1), and goat (n = 2). The rabbit model was similar in size to the neonate, but differences in laryngeal anatomy and cartilage texture made graft insertion difficult. The anatomy of the pig, sheep, and goat larynges more closely resembled the pediatric patient, allowing improved grafting, but corresponded more in size to that of an older child. Commercial availability of the pig and sheep was considered greatest, and was reflected in cost. None of the animal models identified in the literature have been validated as a simulation tool. Conclusions The rabbit, sheep and pig models seemed to demonstrate the greatest potential for use as advanced pediatric airway surgery simulation models, with the rabbit model being most utilized in the literature. However, as yet there have been no models formally validated as a simulation training tool. Laryngoscope, 129:235–243, 2019

“…Ranko Mladina has long advocated and taught and practice sheep's head basic endoscopic dissection training as a cost effective alternative to cadaver dissection . In this issue, Awad et al . evaluate the validity of use of this training model in 70 otolaryngologists who were a mix of trainees and experienced otolaryngologists.…”
