SJD Barcelona Youngsters’s Hospital makes use of 3D printing to resect tumor

The pediatric maxillofacial surgical procedure crew on the SJD Barcelona Youngsters’s Hospital (SJD) has used BCN3D’s 3D printing know-how to efficiently carry out an advanced operation to resect a malignant tumor in an 11-year-old boy. The medical crew led by Dr. Josep Rubio, head of the maxillofacial surgical procedure unit at SJD Barcelona Youngsters’s Hospital, determined to hold out preoperative planning and simulation utilizing BCN3D’s 3D printed know-how and three-dimensional anatomical fashions of the components of the affected person’s cranium, given the complexity of the operation.

The planning consisted of the 3D design of the anatomy of the bounds of the resection to be carried out within the subsequent intervention, creating a picture of the cranium and the affected person’s little one’s tumor, which was then 3D printed within the hospital’s 3D printing laboratory.

The medical crew and the radiologists managed to print each items due to BCN3D’s W27 3D printer from the Epsilon collection – which, with its double extruder head and the supplies (ABS), offered the required realism for the docs to plan the precise surgical intervention based mostly on the precise resection of everything of the kid’s eye tumor (a facial osteosarcoma).

“The purpose of the surgical procedure was to take away a baby’s tumor situated in his cheekbone and to take away the tumor with protected margins. To do that we used 3D planning to delimit the bounds of the resection. These days, 3D planning on the SJD Barcelona Youngsters’s Hospital is commonplace follow in maxillofacial surgical procedure, particularly in very complicated circumstances such because the one we handled on this little one. We needed to create chopping and positioning guides to switch the digital planning from the pc to the working theatre. This has allowed us to execute what we designed just about with precision to have the ability to extract the protection margins subsequent to the tumor as beforehand designed,” defined Dr. Josep Rubio.

The intention of the surgical procedure was to take away Andres’ tumor, which was lodged within the cheekbone, and to take away it with protected margins – which is the place 3D printing know-how got here into play, to plan the operation and precisely delineate the tumor within the cheekbone eye.

“3D printing helped us keep away from potential postoperative issues and improved the standard for each the affected person and the surgical course of. After weeks of surgical planning, we have been in a position to carry out a whole resection of the lesion and in addition protect the affected person’s imaginative and prescient,” mentioned Dr. Adaia Valls, maxillofacial surgeon at SJD Barcelona Youngsters’s Hospital.

Andrés was recognized with retinoblastoma when he was 11 months outdated. When his mother and father determined to have him handled at SJD Barcelona Youngsters’s Hospital in 2016, the medical crew determined to alter his prosthesis in his proper eyeball.

After two years of therapy to deal with the primary tumor, he recovered with a selected therapy. Nevertheless, as Andrés was a service of a germline gene, the docs advised his mother and father that the boy may undergo a sort of most cancers in his bone system, one thing that occurred years later when he developed a facial osteosarcoma.

The oncology crew’s therapy plan was to hold out chemotherapy for 3 months, after which the crew got here to a elementary a part of the therapy – guaranteeing native management of the lesion. For this, it was important to acquire a whole part of the tumor. Different native therapies, comparable to radiotherapy, for such a tumor usually are not as efficient. Along with this – this affected person had already had a radio-induced tumor.

The SJD Barcelona Youngsters’s Hospital is a pioneer in Spain, and Europe, within the analysis and implementation of recent applied sciences. A lot in order that it makes use of 3D printing in additional than 200 surgical procedures a 12 months. Within the hospital’s additive manufacturing service, they’ve, amongst others, BCN3D 3D printers from the Epsilon W27 and W50 collection.

3D printing and planning made its debut at this heart in 2013, after a physician particularly requested a biomodel to enhance the planning of a fancy oncological case. Since then, the usage of this know-how has expanded exponentially, resulting in the creation of a multidisciplinary group of 9 totally different specialties that profit from this know-how.

“We determined to work with BCN3D 3D printers as a result of they’re the machines we often use for planning anatomical bone fashions in maxillofacial surgical procedure and complicated surgical procedure or trauma circumstances. We use supplies that outline glorious chromatic tonalities, accuracy within the printed items, and we receive the most effective outcomes with the effectivity of its double extruder system, printing very practical items,” mentioned Arnau Valls, innovation engineer for the 3D printing service of the SJD Barcelona Youngsters’s Hospital.

Biomodels function a visible help, portraying the anatomical relationships and the connection of the tumor with the totally different anatomical components. They perform as a pre-surgical simulation mannequin, aiding the follow of the cuts to be made by the surgeon. 3D printing helps to customise surgical interventions for every affected person, accelerating the technology of help and steering instruments for the surgeon – comparable to chopping guides and implant positioning, enhancing the precision and security of the surgical procedure. Moreover, the crew on the SJD Barcelona Youngsters’s Hospital 3D planning unit has open strains of analysis to enhance the printed fashions and obtain, by analysis into mechanical properties, colours, and textures, a greater imitation of residing tissues.
