羟基磷灰石(hydroxyapatite,HA)义眼座,是一种具有良好的生物相容性的人工合成生物材料,其成分与人类骨成分相似,内联多孔为纤维血管等软组织提供生长支架,与眶内软组织融为一体,具有对人体无毒、无排斥、无炎症反应和不被吸收等特点,其球体轻,可直接吸附软组织,有利于植入物的固定,作为一种新型眶内充填物,在眼球摘除或眼内容剜除术后眼窝重建中临床疗效显著,近年来得到广泛应用。HA在植入眼眶内2周后就有纤维血管长入,6-8周可达到完全血管化,一般在6个月左右就可以与周围组织形
Hydroxyapatite (HA) orbital implant is a good biocompatible synthetic biomaterial. Its composition is similar to that of human bone. Inline pore provides growth scaffolds for soft tissues such as fibers and blood vessels. It is integrated with orbital soft tissues and has no toxicity, rejection, inflammation and absorption to human body. As a new type of intraorbital filling, it has significant clinical effect in orbital reconstruction after eyeball extraction or enucleation, and has been widely used in recent years. After 2 weeks of HA implantation into the orbit, the fibers and blood vessels grow into the orbit, and complete vascularization can be achieved in 6-8 weeks. In general, it can be related to the surrounding tissue shape in about 6 months.
