Abstract
Abstract Introduction Providing timely and appropriate pressure to prevent/address hypertrophic scarring for burn survivors is an ongoing challenge. From time of measurement to obtaining a custom compression garment can be several weeks requiring creative solutions to providing interim pressure, particularly in the pediatric population and even more challenging for a facial burn scar. Historically, fabric custom garments were ordered, then with the advancement of silicone lined materials, clear facial masks could be fabricated. This process started with taking a plaster cast of the survivors’ face, frequently using sedation to allow for optimal fitting, but sedation can change the tone of the facial muscles adding to the challenge. With the advancements in technology, less invasive, more accurate, and more timely fabrication of face masks is possible. Methods A 3D picture was taken of a 14-month-old pediatric burn survivor with hypertrophic scarring on the face. This image was uploaded to a 3D printer and a positive print (facial surface down) was completed. The positive print was used to make an alginate mask and plaster was poured to create a casting of the positive printed face. A check mask was pulled from this positive plaster cast (+ mask). This check mask was too large for the patient’s face. To have a better fitting mask, another approach to the mask fabrication was completed. From the same 3D picture, a negative print (facial surface up) was completed. Plaster was poured directly into this negative print to create a casting of the negative printed face. A check mask was pulled from this negative plaster cast (- mask). Both check masks were fit to the patient to assess for accuracy of fit and estimation of required adjustments for optimal fit. Results There was a significant difference in the fit of the two masks created from the same 3D picture. The mask pulled on the positive casting was too large. The required adjustments to have the mask fit properly to provide appropriate compression to the hypertrophic scarring on the face would have been extremely difficult and time consuming to complete. The mask pulled on the negative casting fit well and only required small adjustments to ensure adequate pressure would be provided to the focused areas of hypertrophic scars on the face. Conclusions With advances in technology, 3D photography partnered with 3D printing allow for significant improvement in the accuracy of fitting facial masks, improve timeliness of compression, and improve the patient experience in the process of obtaining a facial mask. Applicability of Research to Practice The availability of technology can allow burn survivors to receive compression for facial scars in a faster, more accurate, and patient friendly manner to allow for early intervention to prevent and/or improve facial hypertrophic scarring. From the 3D picture to mask fitting can be as little as 48–72° as compared to several weeks with historical methods.
