Fifty-two methylmethacrylate cranioplasties were performed on forty-seven patients over a five year period. Two cranioplasties became infected and required removal. The overall infection rate for methylmethacrylate cranioplasty was thus 2/52 or 3.8%. Both of these patients had bifrontal cranioplasties involving both orbital rims and the frontal sinus. The infection rate for those cranioplasties involving the frontal sinus was 2 of 9 or 22%. None of the 43 cranioplasties not involving the frontal sinus became infected. Ten patients in this series had postoperative CT scans. Gas within the non-infected methylmethacrylate could simulate infection, making it difficult to diagnose cranioplasty infections by CT. Although certain CT changes, such as epidural air and soft tissue swelling, may be observed only with infected cranioplasties, the clinical picture is the only truly reliable indicator of infection.
在五年期间，对47例患者进行了52次甲基丙烯酸甲酯颅骨成形术。有2次颅骨成形术发生感染，需要取出植入物。因此，甲基丙烯酸甲酯颅骨成形术的总体感染率为2/52，即3.8%。这两名患者均为双侧额叶颅骨成形术，累及双侧眶缘和额窦。涉及额窦的颅骨成形术的感染率为2/9，即22%。其余43例未涉及额窦的颅骨成形术均未发生感染。本系列中有10例患者进行了术后CT扫描。未感染的甲基丙烯酸甲酯内的气体可能会模拟感染，使得通过CT诊断颅骨成形术感染变得困难。虽然某些CT变化，如硬膜外积气和软组织肿胀，可能仅在感染的颅骨成形术中观察到，但临床表现才是感染的唯一真正可靠指标。
