高密度多孔聚乙烯结合自体颅骨外板在眶颧骨折继发畸形修复中的应用

Medpor combined with autogenous outer table of calvarial in management of deformities secondary to orbitozygomatic fracture

目的探讨高密度多孔聚乙烯材料（Medpor）结合自体颅骨外板在眶颧骨折继发畸形修复重建术中的应用。方法将骨折错位愈合的眶颧骨截骨复位进行可靠的内固定后．采用Medpor填充缩孔扩大的眶腔容积，治疗复视，利用自体颅骨外板修复眶罐及眶周的骨质缺损区，恢复眶区外形。结果向2007年1月至2010年12月，共收治眶颧骨折13例。扩大的眶容积得到缩小．眶下缘抬高至对侧水平．眼球内陷叫显改善．复视消失或减轻．面部畸形明显好转．自体颅骨外板及Medpor应用无并发症发乍。结论在复杂眶颧骨折中联合应用Medpor及自体颅骨外板可修复大部分眶颧骨折后继发畸形．尤其是合并骨质缺损患者．可有效解决眶内容物移位、复视．减少自体组织再损伤及排异反应。

Objective To study Medpor combined with autogenous outer table of calvarial in management of deformities secondary to orbilozygomatic fracture. Methods In the reconstruction of the orhimzygomatic fracture, we firstly did the operation of osteotomies to reset reliable internal fixa- tion, then Medpor combined with autogenous outer table of calvarial was used to repair wall and in correction of depressed orbitozygomatic region. Results From January 2007 lo December 2010, 13 cases of deformities secondary to orbitozygomatic fracture were repaired. The enlarged orbital volume was reduced, enophthalmos and facial asymmetry were corrected or improved. Facial deformity was significantly improved and no eomplicalions occurred. Conclusions Medpor combined with autogenous outer lable of calvarial is benefit to most of secondary deformities to orbitozygomatic fracture. It is an effective solution to the orbital content shift and double vision problem, and it also can reduce the autologous damage and foreign Body rejection.
