Using a combination of of 3D modeling, computerized sense of touch and 3D printing, backed by powerful computers, their research is evolving techniques to provide physical models with a "real-life" feel that can be handled in ways that are almost as real as actual surgery. The team has also developed one of the world's first and most advanced haptic temporal bone simulations - a computer generated 3D image that students can "feel" - and they are at the beginning of a mixed reality surgical simulation.
All of these simulation approaches allow the oppportunity to practice on a patient without any inherent risks involved. "There is a really broad array of positive benefits here with this combination of technology says Dr. Unger. "From the perspective of younger surgeons, this provides an opportunity to practice skills, with real-time physical feedback and without impacting the patient. At the other end of the spectrum, more senior, specialized surgeons have the potential to review very specific, very detailed, real information on complicated cases. they can even practice if they feel it is necessary. The applications as we go forward are numerous."
"Human anatomy is incredibly complex, and the details can be incredibly variable", says Dr. Hochman. "We are beginning to evaluate the benefits to patient outcomes. Our aim is to improve the risk profile by providing surgeons an opportunity too appreciate potential challenges before the patient ever enters the operating theatre. It's essentially a dress rehearsal, specific to each patient. We are grateful to the donors of the HSC Foundation for their support in helping us continue our research."
