人脐带在眼眶植入术中的应用

Application of human umbilical cord in the orbital implantation

采用正常人脐带组织包裹羟基磷灰石（HA）填充球用于无眼球畸形眼眶修复15例（15眼）。追踪观察14～18月，平均16月，除3例结膜裂开，其余均无明显并发症，全部安装义眼，外观满意。术前术后外周免疫球蛋白IgG、IgA、IgM和补体C3检测值无显著差别。脐带为胎儿纤维结缔组织，抗原性小，不影响机体免疫系统，可作为眼眶植入体的包裹材料应用于眼眶植入手术中。

Human umbilical cord as a wrapping material wrapped HA globe, 15 cases(15 eyes)with Sockets implanted.Followed up these cases for 14－18 monthes（mean 16 monthes）．There was no special compliction after operation，except 3 cases having conjunctival dehiscences．All 15 cases have got a beter appearance and have been fitted with prosthesis .Immune globulin test examined before and after operation,there were no obvious differences for IgG、IgA、IgM and C3.Umbilical coal is the fetal fibro-ornnective tissue.It has a weak antigenicity,There is no reject rection in the implanting body.So it can be used as wrapping material for orbit implant.
