方法：从2009-01/2012-06用三维CT影像技术及计算机数控成型技术，制作个体化EH复合材料定制体，对35例额眶部骨缺损患者进行手术修复，随访6～24mo。

结果：额眶部形态恢复效果满意，有2例术后发现皮下积液，经针刺抽吸清除及加压包扎后消失。无排异感染等并发症。

结论：个体化EH复合材料具有良好的生物相容性，操作方便，外形满意，术后并发症较少，是一种比较理想的额眶部骨缺损修复材料。

METHODS: Spiral cranial CT and CAD three-dimensional reconstruction imaging were done to declinate the shape and contour of skull defect. The bone defect was repaired by the individual EH compound implants in 35 patients with cranial bone defect due to craniectomy from different disease. The patients were followed up for 6-24 months to evaluate the operation effect.

RESULTS:Postoperative following-up showed that the looks of the patients receiving EH implants successfully were satisfactory and repairing effects were good. Mild collection of the fluid under the scalp was found in 2 cases and disappeared after suction and pressure dressing. No other frequent complications were observed after cranioplasty.

CONCLUSION:Individual prefabricated EH implant is an ideal material of repairing cranial bone because the looks are satisfactory and there are few postoperative complications in the patients with cranial bone defect repaired by the EH implants.
