“…First, our ex vivo ovine model showed to be feasible for parotid gland and facial nerve surgery, confirming results of other reports of the literature. 8,9 Our ex vivo ovine model provided the trainee with close-to-real tissues in term of elastic resistance and consistency, which permit to simulate closely the forces during the incision or dissection, the delicate gesture to use in contact with vascular, or nervous structures. Furthermore, the trainees were able to complete all the surgical steps, with no major difficulties due to the anatomical differences with the human parotid region.…”

“…A preliminary dissection of three heads was performed to assess the feasibility of the training, and as reported by Milner et al and Niimi et al, the ovine model results were adequate and valid. 8,9 Few differences were found between human and ovine parotis. After the preliminary phase, the surgical steps included in the training assessment were defined.…”

“…Furthermore, the vivo or ex vivo animal model have been widely used for the microsurgical training. [4][5][6][7][8][9] The aim of this study is to explore the feasibility and efficacy of a surgical training model on ex vivo ovine head and neck, and to obtain the basic and advanced skills of parotid gland surgery and facial nerve reconstruction/reanimation in a safe environment.…”

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.

“…urgical simulation has emerged as a potential means of effectively training surgeons in a nonclinical setting, but simulation programs frequently are limited by lack of resources, cost, and time constraints in busy academic centers (1). The concept of a short, intensive boot campapproach to surgical skills training has emerged within the last decade and has been well documented in orthopedic (2)(3)(4)(5), neurosurgical (6,7), otolaryngology (8,9), cardiothoracic (10)(11)(12)(13), and general surgery (14) literature, where it has been shown to improve technical skills and confidence for up to 6 months after its completion (15). A similar approach has been described in obstetrics and gynecology (OBGYN) (16), where it is of particular interest given the shorter training of OBGYN residents relative to their counterparts in general surgery (17)(18)(19)(20)(21)(22)(23).…”

Objective: To assess if a surgical boot camp improves laparoscopic skill among reproduction endocrinology and infertility (REI) fellows and increases fellow desire to incorporate surgical skills into practice and to examine whether fellowship in vitro fertilization (IVF) volume correlates with surgical efficiency. Design: Prospective evaluation. Setting: Simulation Center. Patient(s): Forty REI fellows. Intervention(s): Fellows were timed before and after training in laparoscopic suturing and knot tying and while using virtual simulators. Fellows were surveyed before boot camp on prior experience with IVF and reproductive surgery, and immediately and 1 month after boot camp on their desire to incorporate surgical skills into practice. Main Outcome Measure(s): Efficiency of laparoscopic suturing and knot tying before and after boot camp; likelihood and persistence of incorporating surgical skills into practice immediately and 1 month after boot camp; and correlation between fellowship IVF volume and fellow surgical efficiency. Result(s): Fellows experienced significant improvement in laparoscopic suturing (44 sec), intracorporeal knot tying (82 sec), and extracorporeal knot tying (71 sec). Fellows reported being more likely to incorporate operative hysteroscopy (89%), operative laparoscopy (87%), and laparoscopic suturing (84%) into practice immediately following boot camp with no difference 1 month later. Fifty-four percent of fellows reported being more likely to perform robotic surgery after the boot camp, increasing to 70% 1 month later. There were weak correlations between IVF case volume and efficiency in laparoscopic suturing or hysteroscopic polypectomy (Spearman correlation coefficients,-0.14 and-0.03). Conclusion(s): An intensive surgical boot camp enhances surgical skill among REI fellows.
