Polymethylmethacrylate (PMMA) cranioplasty procedures were performed on 20 patients over a 2-year period. Nine of these patients had a total of 17 CT examinations, performed when clinically indicated. On 16 of the 17 CT scans, the appearance of the cranioplasty plate was characteristic of plates with gas bubbles. The appearance of these bubbles was stable over an extended period of time, ruling out clinical reasons for this appearance. The original interpretations of the CT scans were variable, inconclusive, or even erroneous. An understanding of the application of PMMA plates and their characteristics is necessary to accurately interpret the CT appearance of the PMMA cranioplasty plate.
在两年时间里，对20名患者实施了聚甲基丙烯酸甲酯（PMMA）颅骨成形术。其中9名患者在临床指征明确时共进行了17次CT检查。在这17次CT扫描中的16次中，颅骨成形板的外观具有含气泡板的特征。这些气泡的外观在很长一段时间内保持稳定，排除了出现这种外观的临床原因。CT扫描的最初解读各不相同、没有定论，甚至是错误的。要准确解读PMMA颅骨成形板的CT表现，必须了解PMMA板的应用及其特征。
