目的探讨羟基磷灰石义眼座植入后义眼座暴露的原因。方法历例义眼座暴露分别进行B超检查、CT扫描、手术治疗及术后病理检查。结果16例义服座暴露中,眼眶恶性肿瘤1例,炎性假瘤2例,视网膜母细胞瘤术后局部放疗3例,灭性向芽组织增生10例。结论羟基磷灰石义眼座植入后义眼座暴露的发生宰较低。羟基磷灰石义服座是矫正无眼球眶上区凹陷的一种理想的生物材料。
Objective To investigate the causes of hydroxyapatite orbital implants after implantation. Methods Eyelid exposures were performed B-ultrasound, CT scan, surgical treatment and postoperative pathological examination. Results Among the 16 volunteers, there were 1 orbital malignant tumor, 2 inflammatory pseudotumor, 3 postoperative local radiotherapy of retinoblastoma, and 10 exudative bud buds. Conclusion Hydroxyapatite orbital implants have a lower mortality after implantation. Hydroxyapatite prosthesis is to correct non-eyeball supraorbital depression a kind of ideal biological material.
