“…Additionally, no difference was noted whether students were assigned to a high-cost or low-cost model, highlighting better reproducibility of the simulator across institutions. 10 Smith et al arrived at similar conclusions -flexible nasolaryngoscopy on a mannequin, combined with video feedback, resulted in better patient comfort scores, less time to reach the vocal folds, and overall performance scores. 11 There seems to be a paucity of morbidity and mortality outcomes-based studies on the benefit of task trainers and simulators specific to otolaryngology -an avenue for further research.…”

Background. Simulators in laryngology are an essential part of training. They provide an avenue for medical students and resident trainees to practice valuable psychomotor skills outside the realm of an actual patient encounterthereby decreasing the risk of possible patient morbidity. Herein we present three locally manufactured simulation devices that can be used to train residents in laryngology procedures.Objective. To present three simulation platform devices (Laser Box, Flexible Endoscopy Simulation, Thiel Cadaver Chair) and their applications in simulation-based learning Methods. The Laser Box, Flexible Endoscopy Simulation, and Thiel Cadaver Chair were manufactured by outside parties designated as 'Laser Machinists'.Results. Ten (10) units of the Laser Box, two (2) units of the Thiel Cadaver Chair, and two (2) units of the Flexible Endoscopy Simulation were constructed. They were used in a laryngology postgraduate course in our institution to teach the participants on endoscopies and laser phonosurgery. Conclusion.Simulation for otolaryngologic procedures should be an essential part of training. The learning curve for procedures such as laryngoscopy and laser phonosurgery can be addressed with the production of simulation platforms. Most institutions in the Philippines still adopt the "see one, do one, teach one" approach, which lacks standardization and puts patients at risk. Various task trainers for laser phonosurgery and flexible endoscopy have been reported in the literature, but there seems to be no published data on the use of a cadaver chair for simulation. In the COVID-19 era, aside from being excellent teaching tools, simulation platforms derive their importance in helping train residents, educate medical students, and review consultants -maximizing skill development -and thereby decreasing repeated attempts, and indirectly, exposure to the SARS-CoV-2. Future validation studies are required for the models, with the eventual long-term goals to further standardize training, increase patient safety and incorporate a simulation-based curriculum for the specialty locally.

“…In recent years, the application of 3-dimensional (3D) printing technology in medical teaching has been continuously expanding, [2][3][4] and training methods involving highfidelity 3D-printed paranasal sinus models can be employed in nasal endoscopic training as alternatives to the conventional methods. [5][6][7][8] However, in the field of otorhinolaryngology, apart from previous reports on fiber-optic endoscopy, 9,10 there are no reports on the usefulness of training techniques involving models as an approach to aid trainees in transferring their endoscopic skills acquired via practicing on simulators to real-life clinical situations. In order to fill this gap with regard to resident training in the basic techniques of endoscopic sinus surgery, we developed postsurgical simulants and used them in conjunction with validated 3D-printed nasal models in order to teach novice residents, and the Objective Structured Assessment of Technical Skills (OSATS) approach was used to evaluate their performances on the models and on real patients.…”

Background: The use of 3-dimensional (3D)-printed models is promising in nasal endoscopic technique training. Here, we aimed to develop postsurgical simulants for use in conjunction with 3D-printed nasal models and to assess their usefulness in helping residents transfer basic endoscopic skills acquired during simulation training to clinical situations. Methods: The secretion simulant was prepared via a crosslinked reaction between sodium alginate and acrylamide, whereas the packing simulant was prepared using a superabsorbent polymer. A er the simulants' fidelity and utility were evaluated by 5 rhinologists using a 5-point Likert scale, 46 novice residents were trained using the 3D-printed nasal models and postsurgical simulants for 2 weeks. A checklist and Global Rating Scale (GRS) were used to assess their performances before and a er training, and the time to finish each task was also recorded. Following training, the qualified trainees operated on real patients and were reevaluated. Results: The simulants' similarity and usefulness scored ࣙ4.0, and the training cost was 28 CNY ($4 USD) per session. Following training, the checklist and GRS scores increased, and the operation time decreased (all p < 0.05). There were no statistical differences between the trainees' performances on the models with the simulants and on patients (all p > 0.05). Conclusion: The low-cost simulated secretion and dressing are safe to use. The application of the simulants in conjunction with that of 3D-printed nasal models in a simulated task se ing can help residents in transferring endoscopic skills acquired during simulation teaching to real patients.

“…Simulation has been possible in otology and rhinology, and has been enhanced by new technology. 6,7 One of the commonest emergencies in ENT is peritonsillar abscess (or quinsy). Management of patients with this condition, including surgical drainage, is often delegated to the most junior staff in an ENT department.…”

The application of technological advances in medicine has always been more widespread in otolaryngology than in other surgical disciplines. In many ways, this reflects the diversity of our specialty, with otology, rhinology, and head and neck surgery requiring a range of skills, and hence differing equipment. One constant need to allow good surgery to be undertaken is illumination. Mozaffari and colleagues review how advances in light technology have shaped the development of ENT.
