“…Numerous studies evaluating the use of 3D technology in an ENT setting have suggested that it shortens the learning curve for novice surgeons, and others advocate its use in surgical training . In their landmark article, the Southern Surgeons Club group found that 90% of endoscopic surgical complications occurred in the first 30 patients of the learning curve, with the initial risk being tenfold of that after 50 operations .…”

Objectives/Hypothesis Three‐dimensional (3D) endoscopy is an emerging tool in surgery that provides real‐time depth perception. Its benefits have been investigated in surgical training, but the current literature lacks significant objective outcome data. We aimed to objectively compare the efficacy of two‐dimensional (2D) versus 3D high‐definition endoscopes in novice users. Study Design Prospective, randomized crossover study. Methods Ninety‐two novice medical students who used both 2D and 3D endoscopes to complete two validated tasks in a box trainer participated in the study. Time taken and error rates were measured, and subjective data were collected. Results Wilcoxon tests showed 3D technology was significantly faster than 2D (78 vs. 95 seconds, P = .004), and errors per task were significantly lower (3 vs. 5, P < .001). Sixty‐nine percent of participants preferred the 3D endoscope. Conclusions 3D high‐definition endoscopy could be instrumental in training the next generation of endoscopic surgeons. Further research is required in a clinical setting. Level of Evidence 2b Laryngoscope, 129:1280–1285, 2019

“…Multiple training models of EES offer varying levels of realistic experiences to improve surgeon knowledge, surgical skills, confidence, and potentially patient outcomes. 8,10,18,19 Similarly, endovascular vascular injury models have been developed to provide more realistic training. Valentine et al proposed the use of a large animal model that would recreate high-flow, high-pressure injury and allow for objective assessment of the success in management with an evaluation of pre-and postinjury mean arterial pressure, mean resuscitation volume, mean blood loss, and survival time.…”

“…2,6 Acknowledging this, several groups are developing vascular injury models for appropriate training. [7][8][9][10][11] Despite their success, we suspect that current skull base courses may not adequately prepare surgeons to manage this complication and may foster interest in attempting extended approaches, which may inadvertently lead to increased incidence of vascular injury.…”

Injury of the Carotid Artery during Endoscopic Endonasal Surgery: Surveys of Skull Base Surgeons

This study aimed to review endoscopic skull base surgeon experience with internal carotid artery (ICA) injuries during endoscopic endonasal surgery (EES) to provide an estimate of the incidence of ICA injury, the associated factors and identify the best training modalities for the management of this complication. Anonymous electronic survey of past participants at a well-established endoscopic skull base surgery course and a global online community of skull base surgeons. Relative incidence of ICA injuries during EES, associated anatomic and intraoperative factors, and surgeon experience. At least 20% of surgeons in each surveyed population experienced a carotid artery injury. Reported carotid artery injuries were most common during tumor exposure and removal (48%). The parasellar carotid artery was the most commonly injured segment (39%). Carotid artery injuries were more common in high-volume surgeons, but only statistically significant in one of the two populations. Attendance at a skull base course or courses did not change the incidence of carotid artery injury in either surveyed population. In both surveys, respondents preferred live surgeries or active (not computer simulated) training models. ICA injury is underreported and most common when manipulating the parasellar carotid artery for exposure and tumor dissection. Given the high morbidity and mortality associated with these injuries, vascular injury management should be prioritized and taught in a graduated approach by modern endoscopic skull base courses.

Introduction:Neurosurgery is a branch having a tough learning curve. Residents generally get very less hands-on exposure for advanced procedures like neuroendoscopy. With the limited number of cadavers available and ethical issues associated with animal models, practice models, and simulators are becoming the able alternative. Most of these simulators are very costly. We tried to build indigenous inexpensive practice models that can help in developing most of the skills of neuroendoscopy.Materials and Methods:Models were built for learning hand-eye coordination, dexterity, instrument manipulation, cutting, fine dissection, keyhole concept, drilling, and simulation of laminectomy and ligamentum flavum resection. These were shown in the neuroendoscopic fellowship program conducted in authors' institute, and trainees' responses were recorded.Results:Both novice and experienced neuroendoscopic surgeons validated the models. There was no significant difference between their responses (P = 0.791).Conclusion:Indigenous innovative models can be used to learn and teach neuroendoscopic skills. The presented models were reliable, valid, eco-friendly, highly cost-effective, portable, easily made and can be kept in one's chamber for practicing.

Training to acquire psychomotor skills for endoscopic endonasal surgery using a personal webcam trainer

Abstract: Novices using this unique webcam trainer showed improvement in psychomotor skills for EES. The authors believe that training in terms of basic endoscopic skills is meaningful and that the webcam training system can play a role in daily off-the-job training for EES.
