“…While simulation models are used in head and neck surgery, they are not widely applied in surgical oncology. 1,[17][18][19][20] Revascularized cadaver models have been created to facilitate surgical dissection with optimized realism. Other models of revascularized bodies have been developed.…”

The SimLife® model consists in a human cadaver dynamized by pulsatile vascularization. The objective was to evaluate the face, contents, and constructs validity of the SimLife® model in head and neck surgical oncology simulation. Head and neck surgical oncology simulation sessions on SimLife® models were organized with lateral neck dissection and total laryngectomy. Face and contents validity were addressed by questionnaires. Constructs validity was assessed by objective structured assessment of technical skills (OSATS) score. High realism was demonstrated for consistency of tissues (7.1 ± 1.4), color of arteries and veins (7.3 ± 1.9, 8.5 ± 1.1, respectively), and vein consistency (8.5 ± 1.2). The mean OSATS score was 19.7 ± 5.4 for residents and 32.7 ± 1.9 for senior surgeon (P = .0022). SimLife® is a hyperrealistic model for head and neck surgical oncology simulation and it might become a core component of the surgical resident curriculum.

“…Surgical simulation has been validated by several studies, as a reliable alternative and complement to the traditional training during the last decades. 2,3 Fresh human cadaveric specimens are the standard of practice for that purpose. However, their availability and cost and local regulations can limit their use.…”

Introduction Facial nerve palsy has a great physical and psychological impact on patients, so the avoidance of facial nerve damage during surgery and its reanimation are important for Otolaryngologists and head and neck surgeons. The acquisition of anatomical knowledge and surgical training regarding the parotid surgery and facial nerve is mandatory, but not easy to achieve. Surgical simulation is a reliable alternative to the on-the-job learning. In the study, we tested an ex vivo animal model to obtain the basic and advanced skills of parotid gland surgery and facial nerve reconstruction/reanimation. Materials and Methods A prospective cohort study has been conducted on ovine head and neck specimen. A junior resident, a senior resident, and an expert surgeon were involved in a step-by-step preplanned dissection, divided in macroscopic and microscopic. Each procedure was recorded and evaluated by an expert surgeon following an adapted rating scale. Results A statistically significant improvement in terms of execution times and quality of the work was show in most of the surgical steps and for many quality items by the junior and senior residents, while the expert surgeon, as expected, did not show any improvement. Discussion Our ex vivo ovine model provided the trainee with close-to-real tissues in term of elastic resistance and consistency, to learn the skills requested in a head and neck surgery, on a reproducible environment. It is mandatory to have a feedback, which focuses on the quality of the work through valid and reliable assessment of technical skills. The judgment parameters should be reproducible and focused on the specific surgical procedure. Some limitations to this study are present, such as anatomical differences between ovine and human and the limited number of study participants. Conclusion This proposal of training program on the ex vivo ovine model for the acquisition of skills needed in head and neck surgery proved to be feasible, effective, repeatable, and cheap.
