目的

探讨应用个体化模板提供外科设计及术中精确导向定位的临床意义。

方法

选择单侧颧眶颌骨折患者25例,通过术前三维CT扫描,对颅颌骨进行重建。采用计算机辅助设计(CAD)及相应快速成形技术(RP)在健侧的颅面中部骨结构CT数据上制作患侧面中部骨表面的多块(3 ~ 4块)个体化模板,利用模板作为术中导向,精确复位颧眶颌复合体(ZOMC)骨折。

结果

所有患者中,由健侧面中部骨结构CT数据重建的患侧虚拟面中部骨结构继之形成的表面外形模板,均能很好的应用于骨折复位中,各标志点术后水平非对称率均小于3%,单侧ZOMC骨折均获得对称性的复位。

结论

应用CAD和RP联合设计,制作多块个体化模板,通过导向定位精确复位ZOMC骨折,是ZOMC骨折复位重建的新的成功应用。

Objective

To use the individual surface templates of craniomaxillofacial bone in accurate reduction and reconstruction of zygomatic-orbital-maxillar bone fracture.

Methods

Twenty-five cases of unilateral zygomatic-orbital-maxillar bone fracture were observed in this study. Preoperatively, craniomaxillofacial bones were scanned by CT and 3D surface reconstruction of skulls were performed. Then, 3D reconstructions of skull were performed through CT scans. Individual surface templates of fractured side craniomaxillofacial bone, made by technology of electronic computer-aided design (CAD) and rapid prototyping (RP) base on the CT data of unfractured side, were used to guide reduction and reposition of fractured and migrated zygomatic-orbital-maxillar complex (ZOMC) .

Results

Among all cases, the individual CAD templates, were well manipulated in surgery, guiding perfectly reposition and reconstruction of ZOMC. The postoperative horizontal asymmetric rates of each landmark are less than 3%.

Conclusion

On the basis of CAD and RP treatment, the individual templates can be perfectly applied to guide reposition and reconstruction of ZOMC.
