“…Compared to other VR temporal bone simulators, CardinalSim fared favourably in subjective realism [11,12,30]. Content validity was achieved in the Voxel-Man® simulator, but face validity was not achieved due to considerable hesitation regarding the realism of the software [12].…”

“…Common ergonomic complaints were arm fatigue and onehanded simulation, which will be addressed in future iterations of the software with the addition of a foot pedal and armrests. Achieving validity for ergonomics and haptic feedback has also been challenging for other temporal bone simulator research groups [11,12]. Importantly, highly realistic haptics and ergonomics might not be critical for a high-quality training tool.…”

“…After using CardinalSim, participants were asked to complete a face and content validity questionnaire using SurveyMonkey© (San Mateo, CA). The questionnaire was adapted from the surgical simulation literature [11,12]. The questionnaire is provided in the supplementary materials.…”

“…The first two steps are: face validation, the degree to which the simulation resembles the real situation; and content validation, the degree to which the simulation deals with the subject matter of the real situation [10]. Previous studies assessing face and content validity of surgical simulators have presented mixed results possibly due to homogenous, single-centre sample of users [11][12][13]. To address this limitation, we present the first national face and content validity study of a VR temporal bone simulator.…”

“…Although the majority of otologic simulators focus on temporal bone surgery, other platforms exist including a VR myringotomy simulator that recently achieved face, content, and construct validity [17,18]. Virtual reality simulators for temporal bone surgery are well documented and various groups have shown promising benefits for residency education [7,11,15,[19][20][21][22]. However, currently available commercial temporal bone simulators such as Voxel-Man® (Voxel-Man Group, Hamburg, Germany) are still prohibitively costly [23].…”

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.

Background: Training in transcatheter cardiovascular skills today represents a significant challenge because of the complexity of the interventions and an extensive use of multiple live imaging technologies. Objectives: We describe the design, the face validation, and content validation of a newly developed physical transseptal puncture (TSP) simulator using additive manufacturing techniques and novel imaging simulation solutions. Methods: The TSP simulator contains a femoral vein catheterization pad, silicon phantoms of the venous system, a replaceable interatrial septum, and cameras to mimic live fluoroscopic and echocardiographic imaging. A validation study was conducted at the University Hospital of Zurich. A total of 14 interventional cardiologists and cardiac surgeons assessed the TSP simulator. Participants performed a TSP on the simulator using standard interventional tools. Face and content validity was demonstrated using a 5-point Likert scale. Results: The TSP simulator is a new training tool for transcatheter cardiovascular interventions. All interventional cardiologists and cardiac surgeons completed the training exercise and scoring. Overall impression was rated (out of 5) 4.04 ± 1.03, haptic feedback scored 4.13 ± 0.82, and the realism of fluoroscopy simulation 4.39 ± 0.79. Usability was rated 4.50 ± 0.63 by the participants, indicating that the simulator could be suitable for training. Conclusion: We demonstrated face and content validity of a new simulator for transcatheter cardiovascular interventions. The TSP simulator's usability, haptic feedback, imaging solutions, and the overall impression of its usage were reported as very realistic. The TSP simulator represents a promising tool for simulation-based training using real interventional toolkits in a mimicked radiological environment.

Objective To determine how augmented reality (AR) has been applied to the field of otology/neurotology, examine trends and gaps in research, and provide an assessment of the future potential of this technology within surgical practice and education. Data Sources PubMed, EMBASE, and Cochrane Library were assessed from their inceptions through October 2022. A manual bibliography search was also conducted. Review Methods A scoping review was conducted and reported according to PRISMA‐ScR guidelines. Data from studies describing the application of AR to the field of otology/neurotology were evaluated, according to a priori inclusion/exclusion criteria. Exclusion criteria included non‐English language articles, abstracts, letters/commentaries, conference papers, and review articles. Results Eighteen articles covering a diverse range of AR platforms were included. Publication dates spanned from 2007 to 2022 and the rate of publication increased over this time. Six of 18 studies were case series in human patients although the remaining were proof of concepts in cadaveric/artificial/animal models. The most common application of AR was for surgical navigation (14 of 18 studies). Computed tomography was the most common source of input data. Few studies noted potential applications to surgical training. Conclusion Interest in the application of AR to otology/neurotology is growing based on the number of recent publications that use a broad range of hardware, software, and AR platforms. Large gaps in research such as the need for submillimeter registration error must be addressed prior to adoption in the operating room and for educational purposes.
