Abstract

Cranioplasty is a surgical procedure that reconstructs the skull in cases of defects resulting from various causes, with a direct impact on brain protection and the patient's social reintegration. At the University Hospital of Western Paraná (HUOP), cranioplasty with polymethylmethacrylate (PMMA) is routine, but intraoperative manual molding can lead to unsatisfactory aesthetic results. However, there are financial limitations within the Brazilian Unified Health System (SUS) for the use of more sophisticated techniques, as the cost of industrial molds and ceramic or titanium prostheses can exceed R$ 100,000. Thus, there is a need to validate low-cost methodologies, ensuring anatomical precision. This work presents an experience report on the fabrication of a customized mold using a non-industrial 3D printer and the production of a prosthesis with PMMA. An 11-year-old male patient suffered severe traumatic brain injury in November 2021, requiring left decompressive hemicraniectomy, which resulted in a persistent bone defect in the cranial vault. After clinical stabilization and correction of complications, cranioplasty was indicated for brain protection and aesthetic correction. We used the patient's computed tomography images to create a virtual mold, which was 3D printed with biocompatible material, sterilized, and then used as a mold to create the PMMA prosthesis during surgery. The prosthesis was implanted and fixed to the skull according to the standard technique. We conclude that the described technique proved viable, allowing for a cost reduction to less than R$ 800.00, with satisfactory aesthetic results.
