Objective Tympanostomy is one of the most commonly performed surgical procedures in otolaryngology, and its complexity is challenging for trainee surgeons. Investing in medical education is a cornerstone of good patient safety practices. For trainees, use of simulators before operating on actual patients helps mitigate risks. This study aimed to develop a three-dimensional printed model simulator for myringotomy, tympanostomy and ventilation tube placement. Methods An articulated model with a detachable portion, base and plastic bag to simulate the external auditory canal, middle ear and tympanic membrane, respectively, was modelled and printed. Results The final simulator was made from acrylonitrile butadiene styrene polymer and measured 4 × 4 × 12 cm. It was designed to mimic the angulation of patient anatomy in the myringotomy position and simulate the texture and colour of the tissues of interest. The cost was low, and testing with an operating microscope and endoscope yielded satisfactory results. The advent of three-dimensional printing technology has made surgical simulation more accessible and less expensive, providing several advantages for medical education. Conclusion The proposed model fulfilled expectations as a safe, inexpensive, reproducible, user-friendly and accessible surgical education tool that can be improved and reassessed for further research.

“…More complex models also exist. These use a variety of materials, including: a wooden base, tape and 5 ml syringes; 7 silicone sealant, aluminium tubing and plastic sheets; 8 wood, polyester filling, a solution bottle's cap and polyethylene film; 9 a Styrofoam head, a T-pin malleus, a syringe and glad wrap; 10 and polyvinyl chloride, clay, acrylonitrile butadiene styrene and clear plastic. 11 In comparison with our simulator, these models take longer to assemble, and require more specialist skills (such as soldering) and more expensive materials that are not readily available in clinical practice.…”

Objective To develop a simulator of the external auditory canal and tympanic membrane that enables surgical trainees to practise their otomicroscopy skills, which is particularly valuable at a time where there is limited patient contact because of the coronavirus disease 2019 lockdown. Methods A simulator of the external auditory canal and tympanic membrane was made using a cardboard bowl, a 2 ml syringe and a latex glove. The simulator was used to practise otomicroscopy skills, including microsuction, foreign body removal, myringotomy and grommet insertion. Five doctors in the ENT department participated, ranging from core surgical training year two doctor to specialty doctor. Results The simulator provides an effective tool on which surgical trainees can practise, develop and maintain a variety of otomicroscopy skills. Conclusion This inexpensive, easy and quick-to-make simulator enables trainees to practise their otomicroscopy skills on an approximately accurate model during a time when there is minimal clinical opportunity to develop these skills, particularly because of the coronavirus disease 2019 pandemic.

“…In the studies that included assessment of performance (39)(40)(41)(42)(43)45,47,49,(51)(52)(53)(54)(55)59,60,62), different assessment methods and tools were used. These were mainly Global Rating Scales (GRS) where the rater for example assigns an overall score based on observation of the performance (39,41,42,45,(51)(52)(53)(54)(55)62);…”

“…Task-Based/Task-Specific Checklists where the rater for example checks if specific sub-tasks are performed or errors made (41,42,(51)(52)(53)55,62); and metrics such as time to completion of the procedure (39)(40)(41)(42)(43)45,49,(52)(53)(54)(55)60). Two studies used completely automated metrics derived from the VR simulators such as procedure time, contact with the external ear canal, number of attempts of tube insertion, etc.…”

Objective: Myringotomy and ventilation tube insertion (MT) is a key procedure in otorhinolaryngology and can be trained using simulation models. We aimed to systematically review the literature on models for simulation-based training and assessment of MT and supporting educational evidence. Databases Reviewed: PubMed, Embase, Cochrane Library, Web of Science, Directory of Open Access Journals. Methods: Inclusion criteria were MT training and/or skills assessment using all types of training modalities and learners. Studies were divided into 1) descriptive and 2) educational interventional/observational in the analysis. For descriptive studies, we provide an overview of available models including materials and cost. Educational studies were appraised using Kirkpatrick's level of educational outcomes, Messick's framework of validity, and a structured quality assessment tool. Results: Forty-six studies were included consisting of 21 descriptive studies and 25 educational studies. Thirty-one unique physical and three virtual reality simulation models were identified. The studies report moderate to high realism of the different simulators and trainees and educators perceive them beneficial in training MT skills. Overall, simulation-based training is found to reduce procedure time and errors, and increase performance as measured using different assessment tools. None of the studies used a contemporary validity framework and the current educational evidence is limited. Conclusion: Numerous simulation models and assessment tools have been described in the literature but educational evidence and systematic implementation into training curricula is scarce. There is especially a need to establish the effect of simulation-based training of MT in transfer to the operating room and on patient outcomes.
