OBJECTIVE
The number of patients who need cranioplasty after decompressive craniectomy has increased. In most cases, autologous bone flaps are used for cranioplasty, and there have been reports of the complication of bone flap resorption. Based on these facts, we analysed patients who underwent cranioplasty in our institution to learn about potential risk factors of cranioplasty.
METHODS AND RESULTS
We performed a retrospective study and analysed 58 patients who underwent cranioplasty between 2006 and 2013. We found that patients with a defect size >120cm(2) whose reimplantation was delayed tended to have a risk of bone flap resorption.
CONCLUSION
Patients with delayed reimplantation and a defect size >120cm(2) show a tendency of aseptic bone flap resorption. In these cases, a patient-specific implant (PSI) could be the first choice material for this procedure to reduce the rate of this complication.
目的
减压性颅骨切除术后需要进行颅骨成形术的患者数量有所增加。在大多数情况下，自体骨瓣用于颅骨成形术，并且有骨瓣吸收并发症的报道。基于这些事实，我们分析了在本机构接受颅骨成形术的患者，以了解颅骨成形术的潜在风险因素。
方法与结果
我们进行了一项回顾性研究，分析了2006年至2013年间接受颅骨成形术的58例患者。我们发现，缺损面积>120平方厘米且再植入延迟的患者往往有骨瓣吸收的风险。
结论
再植入延迟且缺损面积>120平方厘米的患者表现出无菌性骨瓣吸收的倾向。在这些情况下，定制植入物（PSI）可能是该手术的首选材料，以降低这种并发症的发生率。
