IntroductionBiocompatible computer-assisted design implants for cranioplasty are associated with high costs and considerable waiting time. We present the results of the first cranioplasty experience in our country using polymethylmethacrylate (PMMA) with customized 3D molds of the cranial defect. ObjectivesTo demonstrate the cost-effectiveness of cranioplasty with PMMA using customized 3D molds, compared with computer-assisted design implants. We also describe 3D planning, operative technique, and clinical evolution utilizing this procedure. Materials and MethodsWe present a case series describing five patients with extensive cranial defects who underwent cranioplasty with PMMA using customized 3D molds. From tomographic studies, a bone implant model for the cranial defect was virtually designed and a mold was built according to the specifications of the defect. The mold was printed in 3D using acrylonitrile-butadiene-styrene (ABS). With the sterile mold, the implant could be designed intraoperatively with PMMA to perform the cranioplasty. The evolution, complications, and cost of the implant were evaluated. ResultsNo postoperative complications were observed. Good aesthetic and functional results were achieved in all patients. The cost of the implant per patient using our technique was approximately $350 USD. In our country, the cost of computer-assisted designed implants varies between $10000 and $20000 USD. ConclusionsCranioplasty with PMMA and 3D custom mold is a safe and low-cost technique that would benefit patients in middle- and low-income countries. Compared to computer-assisted designed implants, the cost was reduced by 95-97%. This technique can be implemented on a large scale with remarkable benefits in low- and middle-income countries.
