This study introduces a new method for creating custom cranial implants using 3D-printed molds and polymethyl-methacrylate (PMMA). This technique effectively reconstructs large skull defects, offering excellent cosmetic and functional outcomes.

Area of Science:

  • Neurosurgery
  • Biomedical Engineering
  • Materials Science

Background:

  • Intra-operative molding of custom cranioplastic implants presents significant challenges.
  • Prefabrication of implants aims to improve accuracy and reduce operative time.

Purpose of the Study:

  • To present a novel technique for prefabricating custom cranioplasty implants using 3D printing and PMMA casting.
  • To evaluate the efficacy and outcomes of this technique in patients with large cranial defects.

Main Methods:

  • Utilized 3D printing to create molds for polymethyl-methacrylate (PMMA) implants.
  • Employed computed tomography (CT) scans and digital imaging for precise implant design.
  • Performed cranioplasty on 16 patients with large skull defects (>100 cm²).
