摘要目的 探讨在鼻内镜下,高密度多聚乙烯(Medpor)植入板联合羟基磷灰石(HA)义眼座植入治疗眼眶骨折眼球摘除后眼窝凹陷的临床效果.方法 对眼眶骨折眼球缺失后眼窝凹陷的156例先行HA义眼座Ⅰ期或Ⅱ期植入,后根据眶骨缺损情况在鼻内镜引导下以Medpor植入板填充修补.结果 156例均获良好效果,可见双眼外观基本对称,上眶区饱满无凹陷,患侧眶缘连续,外形良好.Medpor植入板植入后对义眼座活动度有显著性影响.结论 Medpor植入板眼眶填充联合HA义眼座眶内植入治疗合并眼眶骨折的眼窝凹陷效果良好；尤其是在鼻内镜引导下手术,更能使骨折断端达到完美的结合,并能避免损伤周围正常组织.

abstractsObjective To evaluate the clinical effect of the reconstruction of orbital socket with Medpor implant plate for the treatment of hollow eye socket after enucleation of eyeball and orbital fracture under endoscope.Methods 156 cases with hollow eye socket and orbital fracture had been implanted primarily or secondarily with Hydroxyapatite (HA) prosthesis under endoscope.Medpor implant plate reconstruction had been done according to the defection of the orbital bone.Results The results of 156 cases were satisfied,Both sides of the orbit were symmetric on appearance.Superior orbit was full and no depression.The hollow degree of the implants was also symmetric with the other eye.The orbital rims of the affected eye were continuous and in good shape,During the implantation of Medpor implant plate,it would owing significant effect to the motility of HA prosthesis.Conclusion Medpor implant plate should be good material for substitution of the bone,which has good tissue compatability,easy for shape and vascularization and much more better than other materials.Orbital socket reconstration by prosthesis implantation with hydroxyapatite prosthesis combine with Medpor implant plate for the treatment of hollow eye socket and orbital fracture has good effect under Endoscope.
