摘要目的 探讨脱细胞牛心包补片在义眼台置换术中应用的临床效果及安全性.方法 首先将32例(32眼)重度暴露的义眼台取出,将新的义眼台植入肌锥腔,义眼台表面覆盖脱细胞牛心包补片,4条眼外肌对称缝合于补片中央,分层缝合眼球筋膜及球结膜.结果 术后随访6~24个月,所有患眼结膜囊大小适中,无结膜裂开或义眼台暴露等并发症,义眼台位置居中,活动良好,定做义眼片后外观自然仿真. 结论 脱细胞牛心包补片材料取材方便,组织相容性好,免疫反应轻,有一定柔韧性,应用于义眼台置换术安全可靠,效果良好,为义眼台暴露的治疗提供了较好的材料.

abstractsObjective To investigate the clinical application efficacy and safety of bovine pericardium patch in the exchange surgery for exposure of hydroxyapatite implant.Methods The data of 32 eyes of 32 cases with severe exposure of hydroxyapatite implant were taken out of the introrbital implantation firstly and exchanged a new hydroxyapatite implant in the muscle cone cavity.The anterior surface of hydroxyapatite implants were covered by bovine pericardium patch.Four rectuses were stitched to the center of the external patch,then layered suture of fascia bulbi and conjunctiva.Results The follow up time was 6-24 months.No infection,exposure or dislocation occurred.The cosmetic appearance and the pseudo-ophthalmic mobility were excellent.Conclusion Bovine pericardium patch has good histocompatibility and low immunological activity.It is a safe and effective material in hydroxyapatite implant surgery.
