    Abstract Background Trainees in Otolaryngology–Head and Neck Surgery must gain proficiency in a variety of challenging temporal bone surgical techniques. Traditional teaching has relied on the use of cadavers; however, this method is resource-intensive and does not allow for repeated practice. Virtual reality surgical training is a growing field that is increasingly being adopted in Otolaryngology. CardinalSim is a virtual reality temporal bone surgical simulator that offers a high-quality, inexpensive adjunct to traditional teaching methods. The objective of this study was to establish the face and content validity of CardinalSim through a national study. Methods Otolaryngologists and resident trainees from across Canada were recruited to evaluate CardinalSim. Ethics approval and informed consent was obtained. A face and content validity questionnaire with questions categorized into 13 domains was distributed to participants following simulator use. Descriptive statistics were used to describe questionnaire results, and either Chi-square or Fishers exact tests were used to compare responses between junior residents, senior residents, and practising surgeons. Results Sixty-two participants from thirteen different Otolaryngology–Head and Neck Surgery programs were included in the study (32 practicing surgeons; 30 resident trainees). Face validity was achieved for 5 out of 7 domains, while content validity was achieved for 5 out of 6 domains. Significant differences between groups (p-value of < 0.05) were found for one face validity domain (realistic ergonomics, p = 0.002) and two content validity domains (teaching drilling technique, p = 0.011 and overall teaching utility, p = 0.006). The assessment scores, global rating scores, and overall attitudes towards CardinalSim, were universally positive. Open-ended questions identified limitations of the simulator. Conclusion CardinalSim met acceptable criteria for face and content validity. This temporal bone virtual reality surgical simulation platform may enhance surgical training and be suitable for patient-specific surgical rehearsal for practicing Otolaryngologists.

    Temporal Bone Drilling Simulation Boot Camp Course
    (2020-03-26) Hoy, Monica; Oddone-Paolucci, Elizabeth; Dort, Joseph C.; Matthews, Thomas Wayne; Lopushinsky, Steven R.
    Competency by design is changing the surgical landscape. Virtual reality simulation appears to be a promising training tool to assist in achieving surgical competency. This study was designed to determine if a boot camp style virtual reality (VR) mastoidectomy drilling course could be developed to improve a novice learner’s mastoidectomy drilling technique. Forty medical students were randomized to a traditional curriculum (control) group or a VR curriculum (intervention) group. Participants performed pre- and post-intervention knowledge testing, and mastoidectomy drilling sessions. Results of the study are an encouraging first step in demonstrating that a VR simulation boot camp course may improve a novice learners’: (i) understanding of the temporal bone anatomy as demonstrated by a significant difference between pre- and post-intervention knowledge testing (p < 0.01), (ii) drilling technique, as demonstrated by a significant difference between pre- and post-intervention drilling testing (p < 0.01), and (iii) ability to recognize dangerous or red flag areas in drilling a temporal bone. Future directions include a recommendation to implement a mastoidectomy VR simulation boot camp course at the annual Canadian Oto-HNS boot camp.

    The Otolaryngology boot camp: a scoping review evaluating commonalities and appraisal for curriculum design and delivery
    (2022-06-04) Bondzi-Simpson, Adom; Lindo, C. J.; Hoy, Monica; Lui, Justin T.
    Abstract Objective Surgical boot camps are becoming increasingly popular in Otolaryngology–Head and Neck Surgery (OHNS) residency programs. Despite pioneering virtual reality and simulation-based surgical education, these boot camps have lacked critical appraisal. The objective of this article was to examine the adoption and utility of surgical boot camps in OHNS residency training programs around the world. Data Sources Ovid Medline and PubMed databases were systematically searched in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for scoping reviews. Additionally, a grey literature search was performed. Review Methods Inclusion criteria were peer-reviewed publications and grey literature sources that reported on OHNS boot camps for the novice learner. The search was restricted to human studies published in English. Studies were excluded if they were not examining junior trainees. Results A total of 551 articles were identified. Following removal of duplicates, screening, and full text review, 16 articles were included for analysis. Seven major boot camps were identified across various academic sites in the world. Most boot camps were one-day intensive camps incorporating a mixture of didactic, skill specific, and simulation sessions using an array of task trainers and high-fidelity simulators focusing on OHNS emergencies. Studies measuring trainee outcomes demonstrated improvement in trainee confidence, immediate knowledge, and skill acquisition. Conclusion Surgical boot camps appear to be an effective tool for short term knowledge and skill acquisition. Further studies should examine retention of skill and maintenance of confidence over longer intervals, as little is known about these lasting effects.
