Click2Daily: 3-D printing proves to be valuable tool for Houston doctors

HOUSTON – 3-D printing has been assisting surgeons through the most complicated operations imaginable for about four years.

Now, KPRC is getting a behind-the-scenes look at how the printer works and how it benefits patients.

At the Houston Methodist Research Institute, the director of MRI Core works specifically with neurosurgeons to help them map brain surgeries before stepping foot into the operating room.

It starts with an MRI of the brain. A special software converts that scan into a 3-D image. Then, a 3-D printer heats plastic, printing 0.2 millimeters layer by layer on top of each other to create a plastic replica of a patient's brain.

"Takes about 11 hours. Eleven, 12 hours, but once we have that, we have a three-dimensional model," said Christof Karmonik, director of MRI Core at Houston Methodist Hospital.

"What we did in the past makes us look like dinosaurs compared to what we can do now with all this advanced technology," Dr. David Baskin, professor of Neurosurgery at Houston Methodist Hospital, said.

Baskin said now a patient is cosmetically perfect after the reconstruction.

"If you have a bad stroke, have a lot of brain swelling, we actually remove a piece of the skull so there's room for the brain to swell out. It actually saves lives. The only problem is, after it's all over, you've got a big defect, a big hole in your skull. The skull is no longer available, it's been discarded or let's suppose you had a gunshot wound to the head with a patient where their skull was shattered, now you're walking around with a caved-in skull, and the challenges to produce a new skull that will fit perfectly in place," Baskin said. "No matter how good you are, it's very hard for you to contour the exact shape of the skull. But now with computers and 3D printing, we make a CAT scan and the computer reconstructs the way your skull should look and makes a new skull ... and this thing fits like a glove."
