Traditional surgical education has long relied on an apprenticeship model: residents observe attending surgeons and assist in the operating room. While observation is valuable for gaining foundational knowledge, it is inherently passive. Modern medical simulation tools enable hands-on learning that actively engages trainees and bridges gaps in skill acquisition. Evidence shows that high-fidelity simulation training not only improves knowledge but also boosts learner confidence and clinical decision-making.
By allowing students to “clamp, cut, and tie” in a risk-free setting, simulation builds the practical skills and muscle memory that observation alone cannot provide. This article examines why surgical training through simulation is increasingly preferred over observation, especially in complex fields like OB/GYN, and highlights the Miya Model® as a cutting-edge innovation in simulation-based education.
Limitations of Observation-Based Learning
Observation-based learning has clear limitations, especially for junior trainees. New residents often find it hard to know where to focus when simply watching a procedure. As one study notes, when novices observe surgery “they don’t know where to focus their attention,” and they struggle to make sense of what is happening (EM Consulte). Without active involvement, learners miss out on the tactile and decision-making experiences that build surgical judgment.
Observation also depends on case availability and educator time: with declining surgical volumes, many trainees graduate with surprisingly low hands-on experience. Live surgeries carry patient risk and ethical constraints, further limiting opportunities.
In short, purely watching procedures can leave residents underprepared, whereas simulation allows structured practice of critical steps under guidance.
High-Fidelity Mannequins vs. Observation
High-fidelity mannequins (often life-like patient simulators) transform passive learning into active practice. Unlike observation, mannequins let trainees perform full procedures, from basic exams to complex surgeries, all in a controlled environment.
Studies demonstrate that hands-on simulation with mannequins significantly improves knowledge and clinical skills compared to traditional methods. High-fidelity simulation has been shown to boost confidence and critical thinking in medical and nursing students, because it allows trainees to make mistakes safely, learn faster and retain skills longer.
Mannequin simulators also provide immediate feedback (e.g. vital signs, bleeding control), reinforcing correct techniques. In contrast, simply watching a surgery offers no practice of motor skills or decision-making under pressure. In practice, simulation lab sessions are often rated higher for satisfaction and learning effectiveness than lecture-based or observation-only sessions.
Virtual Reality vs. Observation
Virtual reality (VR) simulation takes hands-on learning a step further by immersing trainees in a virtual operating room. VR systems use 3D graphics and sometimes haptic devices to recreate surgical procedures (often laparoscopic or endoscopic surgeries). Like mannequins, VR lets learners practice repeatedly without patient risk, but it also offers unique advantages: for example, complex or rare cases can be simulated on demand. Importantly, VR training has been shown to transfer to real-world performance. In a controlled study of surgical residents, those trained with a VR simulator performed laparoscopic cholecystectomies significantly faster and with far fewer errors than untrained peers (Yale School of Medicine).
Such results suggest that VR training accelerates skill acquisition better than passive observation. VR is also scalable and cost-effective: sessions can be shorter and require fewer proctors while still yielding improvements in technique. That said, VR has limitations (for instance, less physical feedback than mannequins), but as a supplemental tool it provides flexible, immersive practice that observation alone cannot match. In all, VR simulation enhances surgical training by offering realistic, repeatable practice scenarios that build competence far beyond what watching surgeries can achieve.
The Miya Model® vs. Observation
The Miya Model® is a state-of-the-art pelvic surgery simulator designed specifically for OB/GYN procedures. It addresses the shortcomings of observation-based learning in gynecologic surgery by offering an extremely realistic hands-on experience. The Miya Model includes life-size silicone organs, palpable anatomical landmarks, and even a pressurized vascular system that bleeds when cut.
Trainees can practice clamping, cutting, and suturing just as they would on a live patient, complete with the “pop” sensation of passing needles through tissue. According to the National Institute of Child Health and Human Development (NICHD), no other simulator on the market provides this level of surgical detail and training fidelity. For OB/GYN residents, hands-on practice is critical.
Major professional bodies such as the American College of Obstetricians and Gynecologists emphasize that vaginal hysterectomy is the safest approach when possible. Yet these procedures are becoming less common in clinics, meaning trainees may graduate with minimal practical exposure.
The Miya Model bridges that gap, allowing users to rehearse a spectrum of gynecologic procedures (from speculum exams to full vaginal hysterectomy) in a realistic, patient-free setting. By linking OB/GYN education with cutting-edge simulation, the Miya Model helps trainees achieve the clinical confidence and skill mastery required for modern practice.

Why Simulation Training is the Future of Medicine
Hands-on simulation training consistently outperforms passive observation in preparing medical trainees. Whether high-fidelity mannequins, VR systems, or hybrid simulators, this futuristic approach allows for repeated practice of skills, immediate feedback, and builds clinical confidence.
In contrast, observation alone leaves many cognitive and technical gaps. The shift toward simulation-based surgical education reflects this evidence and trainees are becoming more proficient sooner and safer because of training in these realistic environments.
Thanks to simulation tools like the Miya Model® we are able to give residents a chance to perform procedures under lifelike conditions and help ensure they are “OR-ready” before working on patients. Investing in comprehensive simulation platforms not only enhances learning but ultimately leads to safer patient care.
