切取颅骨的技术可分为断层外板(部分外层皮质)、外板(全厚外层皮质)、断层双皮质块和全层双皮质块。骨块的大小可不相同,但切取大块颅骨因技术困难和并发症而常出现问题。切取长于5～6cm、或宽于1.5～2cm的骨块通常不易,有时会发生骨块折裂或穿透颅骨肉板。作者介绍一种使用线锯(Gigli Saw)截取大块、全厚颅骨外板的技术。 Skull removal technology can be divided into the outer panel (part of the outer cortex), the outer plate (full thickness outer cortex), double cortical and full-thickness cortical block. The size of the bone can be different, but cutting large skull due to technical difficulties and complications often appear problems. It is usually not easy to cut a bone longer than 5 ~ 6cm, or wider than 1.5 ~ 2cm, and fracture or penetrating skull plate sometimes occurs. The authors describe a technique for using Gigli Saw to intercept large, full-thickness skull plates.
