Pamela Shavaun Scott and her husband, Michael Balzer can be proud of his stubbornness. This, coupled with the passion of both technology and its design, scanning and 3D printing business managed to Pamela It could save your sense of sight After presenting a tumor at the height of his left than most physicians eye they discarded as relevant.
Mrs Scott had undergone thyroid removal surgery a few months earlier, and already then had good care of monitoring possible side effects. These were presented in the form of a tumor that if not for having been printed in 3D the sense of sight side could have to the spouse of Balzer, who did well to ignore too much of what you told your doctor initially.
Not rely at times can be very important
A few months after the operation, Pamela began to have headaches. After making him a resonance, a mass was discovered inside his brain that corresponded to a 3 cm tumor located behind his left eye. Neurologists who was treated did not seem alarmed and indicated that these masses were common among women, recommending a review in a year.
Balzer disagreed, and in fact he and his spouse had already had good care to choose how and where to perform the extraction of thyroid, which is usually done through a large incision in the throat. The medical center of the University of Pittsburgh was the solution: the use of robotic arms made the incision is much smaller and also much shorter recovery period. Marriage sent the results of the resonance other neurologists and almost everyone agreed: Pamela required an operation.
To try to provide additional information to those doctors, Balzer requested files in DICOM format and soon after, when his wife took him a second resonance, the radiologist was alarmed to see that the tumor had grown substantially. Had he done so? Is that not: Balzer requested the second DICOM file, overlaid the previous, and discovered that the image He had simply taken from another perspective.
Print a 3D skull, that Yes, with included tumor
That made him realize how misleading can be those images, and He ended up creating a 3D model of the skull of his wife with a free program called InVesalius, developed by a research center in Brazil to convert data of resonances in 3D images. The result of that model was an exact reproduction in 3D of the skull of Pamela with tumor, and Balzer not complied by sending the 3D model to doctors: printed in 3D this skull to send him to the University of Pittsburgh, where they were willing to perform a very special surgery.

Ms. Scott, called meningioma, tumor is usually extracted by a procedure called craniotomy, in which the skull opens in two then to physically lift the brain so that they could gain access to the tumor and remove it. Literally. Experts from the University of Pittsburgh assessed that 3D model and they realized that it was possible to access the tumor through the eyelid Ms. Scott. And they did so.
The operation was carried out in may 2014, and neurosurgeon discovered that the tumor was beginning to affect his optic nerves. Having waited six months more, it would have had a permanent and severe degradation of the sense of sight. 95% of the tumor could be removed, and Pamela returned to work three weeks with nearly invisible scars except for her.
The case showed the relevance that is beginning to take the modeling and printing 3D in several areas of medicine, and although the laboratories that work with these techniques often have to face to many difficult regulatory in other areas, it seems that 3D printing will be much easier to integrate into normal processes to be absolutely harmless technique and allowing prepare interventions more accurately.
