Good results were achieved in Ⅰ8 cases of cranioplasty in which a new meterial of medical polymer had been used. The properties of the material and the operation method are also described in this paper, The advantages of the new matiral become more obvious, in comparison with other methods which are usually used in cranioplasty.
目的:探讨儿童颅骨生长性骨折(GSF)的形成机制,诊断和治疗。方法:对我院15例GSF患儿的临床资料进行回顾性分析。结果:15例患儿均有颅脑外伤史,致颅骨线性骨折,骨折线进行性增宽,颅骨缺损,术中均发现有硬脑膜破裂。15例患儿均行手术治疗,3例患儿手术后出现脑积水并予脑室-腹腔(V-P)分流术。结论:颅骨骨折和硬脑膜破裂是发生GSF最重要的因素;患儿发生颅骨线性骨折后应定期复查头部CT,一旦确诊为GSF须行颅骨成形手术治疗;儿童GSF手术后出现的脑积水行V-P分流术治疗效果较好。
As a worldwide challenge in the field of neurosurgery, there is no effective treatment method for pediatric skull defects repair in clinic. Currently clinical used cranioplasty materials couldn’t undergo adjustment in response to skull growth and deformation. An ideal material for pediatric cranioplasty should fulfill the requirements of achieving complete closure, good osseointegration, biodegradability and conformability, sufficient cerebral protection and optimal aesthetic, and functional restoration of calvaria. Biomimetic mineralized collagen-based bone material is a kind of material that simulates the microstructural unit of natural bone on the nanometer scale. Because of its high osteogenic activity, it is widely used in repair of all kinds of bone defects. Recently, the biomimetic mineralized collagen-based bone materials have successfully been applied for cranial regeneration and repair with satisfactory results. This review mainly introduces the characteristics of the biomimetic mineralized collagen-based bone materials, the advantages for the repair of pediatric skull defects, and the related progresses.
