3-D Printing Helps Surgeons Sharpen Their Craft

Printed simulations of lifelike body parts allow surgeons-in-training the opportunity to practice complex surgeries before assisting with the real thing.

Cher Zhao recently had the rare opportunity to practice skills belonging to the most advanced surgeons: reconstructive cartilage grafting.

The setting, however, was fitting for the University of Michigan Medical School resident.

Three-dimensional models based on real cases give surgeons-in-training the opportunity to practice difficult surgeries before assisting on the real thing.

Scalpel in hand, Zhao sat at a table and carved precise measurements out of realistic material designed to mimic the texture of human cartilage.

In the real world, these shapes would be cut from a patient’s rib for grafts used for airway or ear reconstruction. In these procedures, then, it’s vital that the pieces are carved exactly right.

The tool providing Zhao and her peers this immersive experience? Three-dimensional models based on real human cases.

Surgical training is one more way U-M researchers are using 3-D printing to advance the quality of care. The lifelike printed replicas provide a cost-efficient tool to improve practical experience for more trainees such as Zhao, U-M researchers say in an article published in Otolaryngology–Head and Neck Surgery.

Historically, a surgeon’s skills have been acquired in live patients, anesthetized animals or human cadavers, but authors say surgical simulation is increasingly recognized as a vital educational tool.

“3-D printing is bringing a whole new meaning to hands-on experience for surgeons-in-training,” says David Zopf, M.D., the article’s senior author and a pediatric head and neck surgeon at the University of Michigan C.S Mott Children’s Hospital.

“Hands-on experience is critical for acquiring and improving surgical skills, especially of new and complex procedures,” adds Zopf, who keeps a laser 3-D printer in his office. “This is an exciting tool that not only offers trainees exposure to opportunities they otherwise wouldn’t have, but that also allows them to demonstrate proficiency of skills before being performed on children.”
