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.
颅骨成形术是一种常见的神经外科手术，它利用自体骨或异体材料进行颅骨缺损修复。由于各种原因无法获得可用的自体骨时，通常会进行异体材料修复。羟基磷灰石植入物、定制钛和聚醚醚酮（PEEK）因其生物相容性、耐用性和高适配精度而被广泛应用。然而，它们的高成本和有限的可及性使其对普通人来说不太可行。聚甲基丙烯酸甲酯（PMMA）是颅骨成形术中常用的异体材料之一。本报告介绍了一种新颖、经济、定制、3D打印辅助且热聚合的PMMA颅骨修复体制造技术，其精度与定制钛和PEEK颅骨修复体相当。
