4-Year-Old Ready for Kindergarten with His New 3D Printed Prosthetic Ear #3DPrinting

February 12, 2015

For the Medina family, of Clearfield, Utah, a flyer in the mail happened to lead them directly to the specialist who would help four-year-old Tai fit in as he gets ready for kindergarten.

Tai was born with the rare condition of Microtia and Atresia (“little ear”), and without an ear canal; he’s deaf on his right side, where his “little,” or microtic, ear is.

Tai’s parents, Tarra and Ismael, had already gotten him a bone-conduction hearing aid, when they had noticed that Tai was falling a bit behind his peers as he became more verbal. The device certainly helps Tai in his daily life, and improved his speech, but it wasn’t quite an all-encompassing solution.

With school coming up, Tarra and Ismael worried that Tai might face problems fitting in, and potentially even be bullied due to cosmetic differences from his peers. Tarra noted that she does “see people stare sometimes, and that’s kind of hard to deal with,” and worried that that might become even more difficult as Tai moved into school age. Tai, too, wanted “a big ear.”

One day in the mail, the Medinas received a flyer that led them to Paul Tanner, who works at the University of Utah’s Huntsman Cancer Institute in Salt Lake City. Tanner is an anaplastologist who works in the Institute’s Prosthetics Department.

“His presentation showed that he could fasten the prosthetic over the top of his microtic ear, which was huge for us,” – Tarra Medina.

Prior to their meeting with Tanner, the Medinas had been told by every specialist they had seen that for a “big ear” to work out for Tai, they would need to surgically remove his microtic ear — a procedure that seemed both unnecessary and risky. Tanner’s assurance that his prosthetic could be slipped on over Tai’s little ear ensured that this would be the best way to go for the Medina family.

Tanner worked with a CT scan of Tai’s full-sized left ear to create the fully customized, fit-to-stay prosthetic for Tai. By using his left ear as a model, Tanner was able to be certain the new prosthetic would fit Tai’s head and truly look like it fit there.tai medina

Instead of sculpting the ear, I’m able to get a much more accurate model of the ear by doing a CT scan and then flipping it,” Tanner explained.

Once Tanner had the model from the flipped scan, he sent it off to the 3D printing service available at the University of Utah’s J. Willard Marriott Library. Tanner took the 3D printed piece from Marriott Library, created a silicone mold, and painted it to match Tai’s skin color — and it looks like he hit every mark in quality.

It’s 3D printed, it’s a perfect replica of the other ear,” Ismael Medina said when he saw the ear fitted onto Tai.

Tai will need a new ear created about every two years as he grows up, and fortunately with 3D printing technology, that will not be as difficult a task as it sounds. It should also continue to become more cost effective; for this first ear, the Medinas’ insurance covered most of the costs, but their share was still about $1400.

And Tai’s reaction after being fitted for the first time with his new ear? He couldn’t take his eyes (or hands) off his new “big ear” long enough to say, but his mother noted:

“I do see a big old smile on his face right now, so I think he’s pretty excited and I think it will be good for him.”
