Brazilian Researchers 3D-Print Part Of The Face For Cancer Survivor
A Brazilian cancer survivor has been fitted with a prosthetic eye and face to cover the hole that a devastating bout of skin cancer left. Denise Vicentin, 52, beat her cancer a decade ago and has since been living without a part of her jaw and her right eye ever since. Vicentin was so self-conscious about her battle scars, she became afraid to go out in public. People would stare at her everywhere she went and, soon, her social life and marriage fell apart. “[Before] when I was on the metro or train, I tried not to pay attention to the stares. At places like the bowling alley, I felt them looking, and the person would even leave when they saw me,” she told the Daily Mail.
Ten years later, researchers were able to create a custom prosthetic using just a smartphone camera and a 3D printer. Now, she feels like she has her ‘missing piece’ and says she is so happy that she even sleeps with it on.
Years ago, she was offered a hand-made prosthetic, but it would have cost her half a million dollars.
A portion of her right jaw was removed, making it difficult for her to eat and slurring her speech. One of Vicentin’s most painful wounds left behind by the cancer was her inability to navigate throughout society without being ostracized or made to feel different. When doctors offered her the opportunity to have a prosthetic made for her, she had no choice but to turn it down. It would have cost over half a million U.S. dollars.
Waiting for the right moment may have paid off for Vicentin. As technology has advanced, the capabilities of 3-D printing are only just now being realized. Vicentin sought out an alternative treatment at São Paulo’s Paulista University just last year and is already walking into 2020 with a new lease on self-confidence.
The final prosthesis just took 12 hours to create and a fraction of the cost thanks to 3-D printing technology.
The research team at Paulista University formulated a plan to give Vicentin her ‘missing piece.’ Vicentin would have to undergo several surgeries over the next year in order to fit the prosthesis. Then, the doctors took 15 photos of Vicentin’s right eye socket from a simple smartphone. From there, they were able to use all the images to digitize a 3-D model that would eventually become the blueprint for the 3-D printer.
The final model was printed and refined in just 12 hours, from a mixture of silicone, resin, and synthetic fibers. After the 3-D printer created the technical piece that would sit flush on Vicentin’s face, a bit of human artistry was applied to make the prosthetic as realistic as possible. The researchers painted the prosthetic to match Vicentin’s exact eye hue and skin color. They even individually secured lashes to resemble that of her other eyelid.
The research team has been perfecting 3-D prosthetics since 2016, offering new levels of confidence to over 50 patients so far.
Dr. Rodrigo Salazar has specialized in maxillofacial prosthetics for the last few years and has married technology with medicine to create lasting change for his patients. In order to get a proper model for a prosthetic, he used to have to create a mold of the patient’s face, on the patient’s face. Today, he needs only a smartphone camera to capture the necessary data to create a model prosthetic.
Vicentin never expected skin cancer to become a defining chapter of her life.
When Vicentin was in her early 20s, she found a strange growth on her face and went to the doctor. It was a tumor, but it was benign, non-cancerous. She had it surgically removed and thought that was the end of it. It returned again, once again, benign. She had it removed a second time and enjoyed nearly 20 more years tumor-free. Ten years ago, the tumor came back, but it was malignant, slowly ravaging the right side of her face.
Today, Vicentin has titanium hooks surgically placed around her eye socket in order to be able to securely wear the prosthesis and take it off when she pleases. So far, Vicentin has been wearing the prosthetic for just a month and she loves it. ‘It was a long time looking at a face which was missing a piece, so I am so happy. I only took it off to clean it – I even slept with it,” Vicentin told the Daily Mail.
