由于外伤、眶骨膜炎、肿瘤切除等原因,常造成眶骨缺损,轻者眶部皮肤与眶骨形成粘连,造成睑外翻、睑皮塌陷,重者可使眼球向内或下移位。对此常需做眶成形术——眶骨移植或植入充填物。充填材料最初多为自身肋骨、耳软骨、髂前棘、阔筋膜,其后则多用医用高分子化合物,如聚甲基丙烯酸羟乙酯。著者70年代曾多次使用婴儿胸骨及肋软骨,均获良效,但取材受限。1986年后 Due to trauma, orbital periostitis, tumor resection and other reasons, often caused by orbital bone defects, light orbital skin and orbital bone adhesions, resulting in eyelid eversion, eyelid collapse, severe eyeball can be shifted inwards or inwards. For this often need to do orbital angioplasty - orbital bone implantation or implant filling. Most of the initial filling materials for their own ribs, ear cartilage, anterior iliac spine, fascia lata, followed by the use of medical polymers, such as polyhydroxyethyl methacrylate. The author repeatedly used in the 70s sternal and costal sternal cartilage, were good, but drawn limited. After 1986
