内联多孔羟基磷灰石在眼部整形术中的应用

Application of internal linking porous hydroxyapatite in eye plastic surgery

目的 探讨羟基磷灰石在眼部整形中的作用。方法 用国产及进口内联多孔羟基磷灰石包埋入眼眶塌陷处、自体或异体巩膜壳内，置入眼肌锥内。Ⅱ期手术时需将眼外肌缝于相应的异体巩膜壳上，制成可转动的义眼座。保留原眼球外形及眼外肌的生理功能，术后安装义眼片。结果 患者外形矫正满意，义眼活动自如，改善了眼部外观。随访２～１５ｍ ｏ，未见严重并发症、后遗症，术后效果良好。结论 羟基磷灰石是目前眼部整形术中首选、效果最好的材料之一。

Objective To research the role of hydroxyapatite in ocular plastic surgery. Methods Internal linking porous hydroxyapatite was wrapped up in the place of orbital collapse, autogenous or heterogenous scleral shell and implanted in oculus musculi cone. Extraocular muscles were sutured on homologus heterogenous scleral shell as a motiliting integrated pseudoophthalmic implant during the second operation. Outer structure and the physical function of the extraocular muscles were retained in the operation. Pseudoophthalmic was installed after the operation. Results The patients with ocular deformities were corrected very well and the pseudoophthalmic mobility and the cosmetic appearance were excellent. In the follow up of 2～15 months postoperatively, no complication or sequel occured. The effect of the operation was good. Conclusion At present, internal linking porous hydroxyapatite is one of the best materials in occular plastic surgery.
