PURPOSE
The aim of this study was to evaluate the accuracy of resection templates in cranioplasties in order to facilitate a one-stage resection and cranial reconstruction.
PATIENTS AND METHODS
In three cases, cranial resections were combined with direct reconstructions using the principles of computer-aided design, manufacturing, and surgery. The precision of the resection template was evaluated through a distance map, comparing the planned and final result.
RESULTS
The mean absolute difference between the planned and actual reconstructed contour was less than 1.0 mm. After 3 years, no clinical signs of infection or rejection of the implants were present. The computed tomography scans showed no irregularities, and the aesthetic results remained satisfactory.
CONCLUSION
One-stage resection and cranial reconstruction using a resection template, control template, and a prefabricated patient-specific implant of poly(ether-ether-ketone) (PEEK) proved to be a viable and safe method.
目的
本研究旨在评估颅骨修复术中切除模板的准确性，以促进一期切除和颅重建。
患者和方法
在三例病例中，颅骨切除与直接重建相结合，采用计算机辅助设计、制造和手术的原则。通过距离图评估切除模板的精度，比较计划结果和最终结果。
结果
计划和实际重建轮廓之间的平均绝对差异小于 1.0 毫米。3 年后，未出现感染或植入物排斥的临床迹象。计算机断层扫描显示无不规则，美学效果仍然令人满意。
结论
使用切除模板、控制模板和预制患者特异性聚醚醚酮（PEEK）植入物进行一期切除和颅重建被证明是一种可行且安全的方法。
