心脏涤纶补片修复义眼台暴露的临床观察

Clinical observation on exposure of orbital implant repaired by heart dacron graft

目的观察心脏涤纶补片修复中重度义眼台暴露的临床效果及安全性。方法对36例羟基磷灰石义眼台植入术后发生中、重度义眼台暴露进行义眼台修复，用钻磨器等将暴露的义眼台打磨平滑，将直径为20mm的心脏涤纶补片覆盖于表面，修补缺损筋膜结膜缺损区，术后随访6～24个月。结果36例中34例一期愈合，2例结膜愈合不良，经保守治疗，1个月后结膜愈合。无义眼台暴露复发，义眼活动良好。结论心脏涤纶补片是修复义眼台暴露的有效方法。

Objective To observe the clinical efficacy and safety of moderate to severe exposure of orbital implant repaired by heart dacron graft. Methods Thirty-six cases after surgery hydroxyapatite orbital implantation with moderate to severe exposure of orbital implant were repaired. The surface of the exposed hydroxyapatite implant was smoothed by powered grader and covered with a diameter of 20 mm heart polyester patch, to repair the defect of fascia and conjunctiva. The follow-up time was 6-24 months. Results In 36 cases,34 cases were primary healing except 2 cases of poor conjunctival healing. After 1 month conservative treatment,the conjunctiva healed. No orbital implant exposure recurrented. The artificial eyes moved well. Conclusion Application of heart dacron graft is an effective method for repairing of orbital implant exposure.
