摘要
比较用巩膜包裹羟基磷灰石 ( hydroxyapatite,HA)义眼台和不用巩膜包裹的带线 HA义眼台在眼球摘除术后眼眶内植入的疗效。方法 :共眶内植入 HA义眼台 2 32例 ,其中用同种异体巩膜包裹 HA义眼台 48例 ,自体巩膜包裹义眼台 8例 ,带线义眼台 1 76例 ,随诊 5月～ 4年。结果 :共 2 9例 (占 1 2 .5 % )发生与义眼台有关的并发症 ,主要是义眼台暴露 ( 2 5例 ) ,其他为义眼台暴露后合并眶内感染 ( 2例 )、球结膜变薄 ( 2例 )、义眼台植入位置异常 ( 2例 )。异体巩膜包裹义眼台暴露发生率为 1 8.8% ( 9/ 48例 ) ,多数病例暴露范围在 1 0 mm以上 ,须手术处理。而带线义眼台暴露发生率为 8.0 % ( 1 4/ 1 76例 ) ,显著低于异体巩膜包裹义眼台 ( P<0 .0 1 ) ,且暴露范围多在 5 mm内和 6～ 1 0 mm,多可自愈或手术处理容易。结论 :HA义眼台植入术后主要并发症是义眼台暴露 。
To evalute the clinical application and complications of hydroxypatite(HA)orbital implant warpped in sclera or unwarpped Methods:A total of 232 cases receiving the HA orbital implants were observed and follow up from five months to three years 48 were warpped in homologous sclera,8 were warpped in autologous sclera,and 176 were unwarpped which the HA implant with suture were used Results:25 of 232 cases had implant exposure,other complication included 2 cases of infection associted with implant exposure,2 cases of implant malposition,and 2 cases of conjunctival thinning 9 of 48 HA implant warpped in homologous sclera became exposure(18 8%),1 of 8 HA implant warpped in autologous sclera became exposure(12 5%) Most exposure with implant warpped in sclera had large(>10mm)defects and often required surgical intervention 14 of 176 HA implant with suture became exposure(8 0%),and all exposure were small(<5mm)or medium (6～10mm) and often healed spontaneously Conclusion:The main complications of HA implant were implant exposure,using the HA implant with the suture may reduce most exposure
