羟基磷灰石眼台在眼窝重建中的应用

目的探讨羟基磷灰石眼台在眼窝重建中的应用。方法统计分析羟基磷灰石眼台植入501例501眼,局麻或全麻下Ⅰ期植入307例,Ⅱ期植入194例,年龄最大82岁,最小2.5岁。结果480例疗效满意,并发症21例,占4.18%。主要有①眼台暴露18例,10例取出,②结膜切口裂开11例,7例,自行愈合,4例,第二次缝合愈合。结论羟基磷灰石是人体骨组织的主要无机成分,无毒且无抗原性,可安全使用。

The clinical application of hydroxyapatite prosthesis in orbital reconstruction

Objective To evaluate the clinical application of hydroxyapatite prosthesis in orbital reconstruction. Methods The effect of hydroxyapatite prosthesis implantation was analyzed retrospectively in 501 patients with ocular socket sunken. Under local or general anesthesia, 307 cases were implanted at stage Ⅰ, and 194 cases were implanted at stage Ⅱ. The patients ranged in age from 2.5 to 82 years. Results The curative effects of 480 patients were satisfying. Postoperative complications occurred only in 21 patients （4. 18%）, which included implant exposure in 18 patients （implants were extracted in 10 cases） and conjunctival wound dehiscence in 11 patients （7 cases healed spontaneously and 4 cases were managed by secondary suture）. Conclusion Without toxicity and antigenicity, hydroxyapatite is a safe material for prosthesis in orbital reconstruction.
