Abstract

Polymethylmethacrylate (PMMA) is a self-curing acrylic resin that can be used in the repair of cranial defects. It is available in three forms: PMMA without mesh, PMMA reinforced with mesh, and PMMA preformed to fit a defect. In cranioplasty, the size and location of the defects provide the selection criteria for the use of PMMA. PMMA without mesh is ideal for small defects (5 cm2-15 cm2). PMMA reinforced with mesh is used for moderate sized defects (16 cm2-49 cm2). For very large defects (> or = 50 cm2), a CT scan guided mold is recommended because it provides the ideal contour and shape that simulates the normal skull.

摘要

聚甲基丙烯酸甲酯（PMMA）是一种可用于修复颅骨缺损的自固化丙烯酸树脂。它有三种形式：无网孔的PMMA、带网孔增强的PMMA以及预成型以适配缺损的PMMA。在颅骨成形术中，缺损的大小和位置为PMMA的使用提供了选择标准。无网孔的PMMA适用于小缺损（5平方厘米至15平方厘米）。带网孔增强的PMMA用于中等大小的缺损（16平方厘米至49平方厘米）。对于非常大的缺损（≥50平方厘米），建议使用CT扫描引导的模具，因为它能提供模拟正常颅骨的理想轮廓和形状。
