羟基磷灰石义眼座二期植入矫正眼窝凹陷

Coralline Hydroxyapatite Spheres as Secondary Orbital Implant in Anophthalmos

目的 探讨羟基磷灰石 (HA)义眼座矫正眼窝凹陷二期植入术的方法和疗效。方法 应用美国产HA义眼座为 4 7例单侧丧失眼球者进行二期植入 ,手术分为 3种 :植入物更换术、眼球摘除后二期植入术及眼内容剜出后二期植入术。结果 所有患者的眼窝凹陷均得到了有效矫正 ,配戴合适义眼片后外观对称 ,联动式义眼片活动度在 15°～ 35° ,非联动式义眼片 10°～ 2 5° ,手术并发症少。结论 HA义眼座是目前较为理想的眶内二期植入材料。

Objective To detect the methods and curative effect of secondary HA orbital implants to rehabilitate the anophthalmis socket.Method HA orbital implants (made in America) were used as secondary orbital implants in 47 unilateral enucleation patients.All patients were divided into three groups:①implants replacing surgery;②secondary implantation after enucleation;③secondary implantation after evisceration.Result All patients attained improved prosthesis apparence with few complications.Motility of integrated orbital implants is in 15°to 35°and Motility of non-integrated orbital implants is in 10°to 25°.Conclusion HA orbital implant is ideal material for secondary orbital implantation.
