摘　　要：【目的】分析多孔羟基磷灰石 (HA)义眼台眶内植入后的并发症并探讨其原因。【方法】回顾眶内植入羟基磷灰石义眼台 32 0例 ,随诊 6月～ 4年。【结果】 32 0例中发生并发症的有 46例 (14 4% ) ,其中义眼台暴露 41例 (12 8% ) ,义眼台位置异常 2例 ,其它并发症包括义眼台慢性感染、结膜肉芽肿等。义眼台暴露的发生时间为术后 7d～ 6月 ,范围为 2～ 15mm。【结论】羟基磷灰石义眼台眶内植入最常见的并发症是义眼台暴露 ,并发症的发生原因与多种因素有关 ,包括术前眼病史、包裹义眼台的异体巩膜的排斥溶解、义眼台的选择、缝合技术、术后眼眶的放射治疗等。Objective To analyse the complications of porous hydroxyapatite orbital implants and the causes leading to the development of these complications. Method A total of 320 cases of hydroxyapatite sphere orbital implantation were reviewed retrospectively, and follow up from six months to four years. Results Forty six of them developed complications (14 4%), of which forty-one cases had implant exposure, two cases had implant malposition, other complications included chronic implant infection, conjunctival granuloma and conjunctival thinning. Exposure of the implant occurred from 7 days to 6 months after surgery. The size of exposure ranged from 2 mm to 15mm. Conclusion The most frequent complication of hydroxyapatite sphere orbital implantation is implant exposure. Several factors, which affect the occurrence of complications, include previous ocular history, exclusion and dissolution of the homologous sclera wrapping implant, surgical technique and radiation after implantation.
