The migration or passive intracranial translocation of microplates and screws in the pediatric craniofacial patient has been reported. A retrospective review was undertaken to clarify the incidence of microplate translocation and identify potential clinical implications. Computed tomographic imaging demonstrated internalization of microfixation in 14 of 27 pediatric patients. Statistically significant factors for microplate translocation include longer plates (p < 0.05) and those placed in the temporal region (p < 0.001). Younger patients and those with syndromic craniofacial dysostosis also had a higher incidence of translocation. Specific complications relating to the translocation of microplates were not found in any patient. The direct effects of translocated microplates and screws on the underlying brain and dura remain unclear.
小儿颅面患者中微型钢板和螺钉的移位或被动颅内移位已有报道。本研究进行了一项回顾性分析，以明确微型钢板移位的发生率，并确定其潜在的临床意义。计算机断层扫描成像显示，27例小儿患者中有14例微型内固定装置发生了内移。微型钢板移位的统计学显著因素包括钢板较长（p < 0.05）以及放置在颞部区域（p < 0.001）。年龄较小的患者以及患有综合征性颅面骨发育不全的患者移位发生率也较高。在任何患者中均未发现与微型钢板移位相关的特定并发症。移位的微型钢板和螺钉对其下方脑和硬脑膜的直接影响仍不清楚。
