From Superhero Mask to New Face and New Life Thanks to 3D-Printed CMF Implants
Imagine being called a freak all throughout your life. It’s exactly what happened to Carlos Askew. Born with hemi-facial microsomia, the 21-year-old Kiwi never fit in, no matter how hard he tried. Growing up, the youngster preferred hiding behind the mask of his favorite superheroes instead. Until consultant maxillofacial surgeon Dr. Derek Goodisson (New Zealand) used TruMatch® CMF 3D-printed patient-specific titanium implants to mitigate his facial deformity. This pioneering operation was a first in New Zealand and, more importantly, enabled Carlos to face the world anew.
The congenital disorder hemi-facial microsomia (HMF) is caused by an in utero vascular malfunction that results in an underdevelopment of structures related to the affected artery. In Carlos’s case, HMF manifested itself in facial asymmetry and left him partially deaf. If that wasn’t enough of a rough start, Carlos was placed in state care, shunted from family to family, and abused until he arrived on the doorstep of his current foster family, the Askews.
Now 21, Carlos wants what most young people his age want: a social circle, a job, and someone special in his life. But for him, his asymmetrical face remains the biggest obstacle to achieving this ‘normal’ life. An obstacle that made him feel worthless to a point where he contemplated suicide.
CMF implants designed to fit
Thanks to 3D Planning and Printing, Carlos can finally start building the life he has been dreaming of. To achieve this milestone, consultant maxillofacial surgeon Dr. Derek Goodisson worked in close collaboration with DePuy Synthes and Materialise engineers to design the patient-specific titanium implants that would mirror the non-affected bones, ultimately giving Carlos a more symmetric face. This complex surgery required a high level of accuracy, which is exactly where the ProPlan CMF® planning software played such a key role: this virtual planning and design process enabled the creation of tailor-made implants, as well as a predictable outcome from the start.
Additionally, Materialise provided patient-specific drilling and cutting guides to predrill the screw holes for the implants and to mark the vertical portions of the sagittal split osteotomy.
A new face, a new start
This also reduced the operation time as the preoperative plan facilitated an accurate position of the 3D-printed implants, and, consequently, helped save time in the operating room. Once the patient-specific implants had been designed, approved, and 3D printed, Carlos Askew was ready to undergo the makeover of a lifetime. Maxillofacial surgeon Dr. Derek Goodisson and his team worked nine hours to separate and to shift the upper jaw and mandible into a central position, before inserting the customized titanium implants – an absolute first in New Zealand.
Carlos Askew’s story showcases the true potential of 3D Planning and Printing. The ProPlan CMF® software enabled the creation of detailed preoperative plans, allowed for the design of patient-specific implants, reduced the number of intraoperative decisions as well as the turnaround time, and facilitated a more predictable outcome. The customized fit helped restore the symmetry of Carlos’s face. But more than anything, this pioneering surgery improved Carlos’s quality of life significantly.
