Scan of Shavaun's Skull / Tumor


October 20, 2014

There is nothing scarier in this world, than being told that you or a loved one has been diagnosed with a brain tumor. For one woman, this happened toward the end of last year, but thanks to her husband, Michael Balzer, who was versed quite well in 3D technology, her diagnosis, treatment and recovery went a lot better than expected. For those unfamiliar with Michael Balzer, he is the producer of a podcast and website called, All Things 3D.

“My wife was diagnosed with Menigioma, but the diagnosis was minimized until I was able to review the DICOM information myself and present 3D volume renderings to her to convince her to get another CT with contrast,” Michael Balzer tells “This led to more accurate discovering of [a] 3.5 cm Meningioma in her upper left orbital roof. I was then able to create 3D sagital models, which I then loaded on SketchFab for neurosurgeons to review as we shopped for a neurosurgeon who would remove it using [a] minimally invasive procedure. This process took us three months and we narrowed it down to John’s Hopkins and UPMC (University of Pittsburgh Medical Center).”

Michael then 3D printed two full-scale sagital sections and sent them to the surgeons. UPMC ended up being the only medical center willing to move forward with the new minimally invasive technique, due to the physical models and the imaging that Michael has provided. You can see the 3D scan/model of his wife’s tumor located on the base of her skull below (the ‘after’ model can be seen at the bottom of this article):

In mid-May, an eight hour surgery was performed, through her upper eyelid. Incredibly 95% of the tumor was able to be removed, and just three weeks later, she was back at work, seeing clients again. Michael tells us that she is now almost completely back to normal.

“If it were not for forward think surgical team at UPMC and their research in minimally invasive techniques, this may not have such a happy ending,” said Michael.

Michael still uses 3D scanning technology in order to help provide his wife’s neurosurgeon and optomologist surgeon with periodic updates on her recovery. He does this using a Sturcture Sensor 3D scanner, along with a 4eyes lens attachment product that he sells for the Structures Sensor and iSense scanners. Michael uploaded a 3D model, showing his wife’s progress on Sketchfab, which can be seen below. “Other than the optical distortion, you can clearly see the healing and disparity between eyes, notably the left eye,” Michael explains to us.

“I have not uploaded the latest, but unless you really look now, you would not be able to tell she had any surgery, let alone brain surgery,” explains Michael. “A testament to how far we have come in just five years, where her only recourse would have been for [her] to have 1/3 of her skull removed and brain lifted to remove it. As one neurosurgeon said, this most certainly would [have] caused long lasting problems, including the loss of smell, taste and even the sight in the left eye. 30 years ago she would have died like her mother did at the age of 52. [My wife] just turned 56 eight days ago.”

This goes to show, that perhaps more doctors, surgeons and medical researchers should be using 3D scanning and 3D printing technology, but for one reason or another they are not. That reason is most likely due to the lack of knowledge, and lack of funding for such technology. In Michael’s wife’s case, she was lucky to have a husband as caring and well educated as Michael, complimented by surgeons and a medical center willing to cooperate.

Michael Balzer is grateful for 3D technology, as is his wife. He wants to help spread the knowledge of what 3D technology can do for the medical field, so on October 29th from 6:00 – 8:00 p.m. PST in San Luis Obispo, CA, he will be holding a free seminar titled “3D in Medicine” (site live soon). On hand, will be several 3D medical experts, and the entire presentation will be livecasted via Google Hangouts On Air, via a multiple camera setup. The presentation will show viewers just how medical scanning works, as well as how you yourself can take your own medical scans and turn them into 3D printed models.

What do you think? Will 3D printing ultimately lead to more successful surgeries? Do you plan on watching or attending this presentation? Discuss in the 3D in Medicine forum thread on  Check out the post-surgical 3D model of Michael’s wife’s skull below (note the large 3.2cm hole which the surgeon has minimized).
