Cranioplasty is a common neurosurgical procedure which makes use of autologous bone or alloplastic material for cranial defect reconstruction. Alloplastic reconstruction is routinely done in cases where viable autologous bone is not available due to various reasons. Hydroxyapatite implants, patient-specific titanium and PEEK are widely employed materials due to their biocompatibility, durability, and high adaptation accuracy. However, their high cost and limited availability make them a less viable option for the common man. Polymethyl methacrylate (PMMA) is one of the commonly used alloplastic material for cranioplasty. This note presents a novel, economic, patient-specific, 3D printing-assisted and heat polymerized PMMA cranioplast fabrication technique with an accuracy comparable to that of patient-specific titanium and PEEK cranioplast.
