Segment:1 Interview with David Dunaway (Great Ormond Street Hospital; London, UK).

DAVID DUNAWAY: I'm David Dunaway. I'm a Consultant Craniofacial Surgeon at Great Ormond Street Hospital and Professor of Craniofacial Surgery at the UCL Institute of Child Health. I'm a plastic surgeon by training, but also trained as a dentist. For most of my working career as a consultant, I've been at Great Ormond Street Hospital with an interest in treating children with congenital facial deformities.
Segment:2 3D technologies at Great Ormond Street Hospital.
DAVID DUNAWAY: 3D technologies are really important to us from the point of view of analyzing the very complex cases we have. Those started off with simple imaging, but now we're moving into printing. We're using printing and milling 3D shapes in lots of different ways, so for making models that help us understand the anatomy of bones and blood vessels. We also use those for patient education. We're using 3D printing for surgical guides that help us perform surgery more accurately, and we're also using materials that are printed and milled as patient-specific devices, so implants, for example, that help us with our reconstructions.
DAVID DUNAWAY: I think 3D technologies are really important for modern-day craniofacial surgery because they help us to understand. For us, with our most complex cases, we often use those technologies to help us interpret the information we have because, with modern imaging technologies, you get so much data that, in many ways, we've got data overload. So it's very, very difficult for us to understand all the information we have. By 3D printing things, it simplifies the data. It gives you something that you can pick up and hold, and it gives that data a very human aspect because I guess, when it comes down to it, surgeons, to an extent, are craftsmen. To be able to pick things up and practice what you're going to do I think is really important for us delivering good care for our patients.
Segment:3 3D printing for complex cases.
DAVID DUNAWAY: So I think, for our most complex anatomical cases, 3D printing is becoming very much a standard. For those rare cases, which we see infrequently, we would usually not consider doing them unless we had a 3D-printed model. I think, to demonstrate that, the best case is perhaps the separation of the conjoined twins that was recently published. So these were two twins, Safa and Marwa, who were joined at the head. They had a very complex arrangement of the way their heads were joined together, the alignment of their brains inside their heads, and very, very complex vascular anatomy, the shape of the blood vessels. In fact, I think they were by far the most complex set of conjoined twins that we've seen in a craniofacial unit. Those 3D-printing technologies allowed us to sort of engage with the information we have, make roadmaps for dividing the blood vessels. They guided our bony reconstruction and helped us to plan the skin reconstruction in a good way. And, actually, I think, without those 3D technologies, we wouldn't have been as successful as we have been in separating them. In fact, I think it may not have been possible.
Segment:4 Embedding 3D printing at the point of care.
DAVID DUNAWAY: So I think 3D technologies are going to become more and more important. On a simple level, I think access to 3D models is becoming so much more routine. 5 or 10 years ago, you would have to apply for funding to get them printed and they would take weeks to print, whereas now we have our own in-house 3D facility, and we're printing our own models, and they've become very routine. And that's made them so much more useful for us because not only are we able to get them for more patients, but that's allowed us to learn how to use them.
Segment:5 The future of 3D printing technologies for surgery.
DAVID DUNAWAY: The 3D technologies, though, I think will really take off in different ways. So the way I see things going is that now we have these models, and we interact with them before surgery. But it won't be long before the information we gain from them is loaded into augmented reality, and we will be using neuronavigation equipment in the theater so that, actually, the information that's contained within the models will be visible on the patient. I think that allows you to see what's going on in the layers deep and hidden from you and would, I think, allow us to undertake our surgery in a much more precise and effective way. In addition, I think, as biomaterials become more printable, more millable, we're going to see 3D-printed technologies in reconstruction. So now, for example, we use titanium and PEEK implants to make reconstructions, but, as these things get more sophisticated, the materials become more biocompatible, I think they are going to become a routine in these complex and maybe simpler reconstructions as well.
