There have been a lot of news stories lately about advanced 3D modeling software and 3D printing technology being used to aid doctors with surgical pre-planning or to help them understand the nature of a specific patient’s needs. 3D printed hearts, 3D printed livers and even a highly realistic 3D printed brain have all been found to be invaluable in helping doctors make difficult or complex surgeries faster, safer and more precise. But 3D printing isn’t just a useful surgical pre-planning tool; it is also a great way for doctors to help their patients understand how exactly they are planning to help them.
Depending on the procedure, it is often quite common for many patients to have very little idea of what exactly is going to be done to them. Not only is it difficult to explain complicated surgeries to patients who may not have a full understanding of how the body works, but many doctors, while quite talented surgeons, simply may not have the ability to clearly explain the problems that they are facing during the process in a way that the patient can understand. This is often a source of anxiety for many people, and it could potentially lead them to make medical decisions that may not be in their best interest.
But a pair of doctors from Australia’s Peninsula Health have been exploring ways to better help their patients understand the nature of their injuries or health issues by using 3D printed models as visual aids. The idea is a simple one: when a patient may have trouble understanding what exactly is wrong with them, and how it needs to be fixed the doctors can use MRI and CT scan data to 3D print exact copies of their tumors or even detailed recreations of their broken bones before they have surgery. 3D printing can also help patients understand what happens after the surgery, for instance if they have a tumor on their jawbone, the doctors can print that and then use software to remove the tumor and print a second jawbone that can be compared to the first.
“If you can print them you can hold them and turn them around in your hand … it’s an exact model — it’s less than 1 per cent off and that’s not clinically relevant. We can subtract (the tumour off) and it leaves you with the underlying jaw without the tumour … for patient education and pre-operative planning it’s really good,” director of surgical research Associate Professor Hunter-Smith explained to the Herald Sun.
Amusingly, Hunter-Smith and a junior doctor at the hospital, Michael Chae, weren’t even in the same room when they both had the idea at the same time. Both doctors were looking through a medical catalog and stumbled on an ad for a discounted 3D printer that would allow them to create visual aids for their patients. So with the approval of Hunter-Smith, the 26-year-old Dr. Chae has taken the lead in helping expand the hospital’s use of 3D printing for not only research, but improving overall patient care.
“Myself and Professor Hunter-Smith read an advert that there was a 3D printer on the market for only $1400 … then the emails started. Our focus of research here at Peninsula Health in Frankston is multifold — but the main point of our work is to make this technology available at the bedside. We’ve shown that 3D printing is helping for planning surgeries and for education. Hopefully it will translate into better outcomes for patients but we don’t know that yet — it’s bit early,” said Dr Chae.
Helping patients better visualize the procedure that they will be having done to them will hopefully help them make better, more informed medical decisions. But patients aren’t the only ones who benefit from these types of 3D visualizations. Doctors for instance, can 3D print broken or even shattered bones and practice reconstructing them before they ever open the patient up. Not only does it give them a better idea of how to put the bones back together, but it reduces the amount of time they need to do so, as well as potentially preventing further surgeries.
