眼球异位是外伤后眶壁骨折畸形的常见后遗症 ,眼球复位对患者视觉功能及外观的改善有重要意义。自 1997年 10月以来 ,应用多孔聚乙烯外科种植材料行眶内填充矫正眶周骨折后眼球异位畸形 9例 ,手术效果良好 ,术后 6个月随访无排异 ,吸收 ,移位等情况。该材料组织相容性好 ,术中能根据临床要求塑形 ,机体组织能长入其多孔间隙中增加材料稳定性 ,与以往多种眶内填充材料相比具有多种优点
Ocular ectopic is a common sequelae of traumatic orbital fracture deformity. Reoperation of eyeball is important to the improvement of visual function and appearance of patients. Since October 1997, 9 cases of ocular malformation after periorbital fractures were treated with porous polyethylene surgical implants, and the results were good. No abnormality, absorption and displacement were observed after 6 months of follow-up . The material has good histocompatibility and can be shaped according to clinical requirements during operation. The body tissue can grow into the porous space to increase the material stability, and has many advantages compared with the conventional multiple orbital filling materials
