Application of polyester fiber heart patches to secondary intraorbital implantation of hydroxyapatite spheres

观察采用涤纶心脏补片包裹羟基磷灰石（ＨＡ）义眼座置入的效果。方法 对已行眼球摘除的患者根据肌肉收缩点寻找直肌并制做４条直肌瓣，然后行ＨＡ义眼座眶内置入术。结果 本组共１３例，１１例一期愈合，２例前部球结膜和筋膜局部愈合不良，其中１例经单纯修复后愈合，另１例未经特殊治疗自行愈合。结论 用涤纶心脏补片包裹ＨＡ义眼座行二期眶内置入效果肯定，安全可靠、使用方便、价格便宜易得。

Objective To observe the effect of intraorbital implantation of hydroxyapatite spheres wrapped with polyester fiber heart patches. Method According to the rectus contraction points four rectus were found and the rectus valves were created in anophthalmos. Then the hydroxyapatite sphere wrapped by the polyester fiber heart patch was inserted in the orbit. Result There were 13 cases in this group. Of them 11 patients showed very good operative results, Local poor healing of bulbar conjunctiva and fascia occurred in 2 patients. The wound in One patient healed very well after a simple repairing operation and in the other the wound healed spontaneously without any special treatments. Conclusion The effect of secondary intraorbital implantation of hydroxyapatite spheres wrapped by polyester fiber heart patches is positive. The polyester fiber heart patch is safe, reliable, cheap, very convenient in use and easy to obtain. It is a better substitute for sclera which is used to wrap the HA sphere.
