This study evaluates the use of a new calvarial bone graft-harvesting device (BHD).
A total of 18 calvarial bone grafts (CBGs) were harvested from 9 cadavers with the BHD. The recorded parameters included drilling time, graft harvest time, graft size, graft integrity, and violation of the calvarial inner table. Five CBGs were subsequently harvested in vivo and used for 2 nasal reconstructions and 3 orbital reconstructions.
The CBG dimensions ranged from 1.25 to 2.5 cm in width and 3.0 to 16.0 cm in length. Graft harvest time ranged from 5 minutes, 55 seconds to 25 minutes, 30 seconds (mean 13 minutes, 7 seconds). There were no fractured grafts. The cadaveric inner table was violated twice with a cutting burr, and 1 dural exposure occurred in the clinical study.
Although caution must be used with all CBGs, the BHD appears to be safe and more efficient than osteotomes or oscillating saws.
本研究评估一种新型颅骨骨移植采集装置（BHD）的使用情况。
使用BHD从9具尸体上共采集了18块颅骨骨移植（CBG）。记录的参数包括钻孔时间、移植采集时间、移植尺寸、移植完整性以及颅骨内板的破损情况。随后在活体上采集了5块CBG，并用于2例鼻再造和3例眼眶再造。
CBG的尺寸宽度为1.25至2.5厘米，长度为3.0至16.0厘米。移植采集时间从5分55秒至25分30秒不等（平均13分7秒）。没有移植骨骨折。尸体的内板有两次被切割钻侵犯，临床研究中有1次发生硬脑膜暴露。
尽管使用所有CBG时都必须谨慎，但BHD似乎比骨凿或摆动锯更安全、更高效。
