摘　　要：目的 :探讨用羟基磷灰石材料 (Hydroxyapatite,HA)行眶颧再造的效果。方法 :2 2例外伤或幼年眼球摘除及放射治疗后导致的眶颧塌陷畸形 ,采用羟基磷灰石板块状多孔材料充填再造 ,术前参照健侧眶颧形状预制HA植入块 ,切口设计为颞侧发际内的隐蔽皮肤切口。HA块充填并以颞浅筋膜瓣覆盖HA块。结果 :眶颧充填再造术 2 2例 ,平均随访 15 4个月 ,未见植入物移位、变形或脱出。结论Objective:To evaluate the effect of orbitozygomatic reconstruction with coral porous hydroxyapatite (CHA).Methods:22 cases of orbitozygomatic defect caused by trauma,enucleation of eye ball or radiotherapy at early age were treated with CHA,which is a plate form mass with an interconnected system of canals of approximately 200 μm in size.According to the shape of the contralateral normal orbit and zygoma,a rubber putty model was made before operation.Incision was designed at the temple region.A correctly molded CHA implant was inserted as a bone graft substitute to enlarge the orbitozygomatic region and covered with temporoparietal fascia with vascular pedicle.Results:The orbitozygomatic defect in 22 cases was successfully treated with CHA.During a follow up of 6～48 months,there was no extrusion or migration of the implant.Conclusion:The procedure of orbitozygomatic reconstruction with CHA is effective and safe.
