121例多孔聚乙烯义眼座眶内植入的临床分析

The Porous Polyethylene （Medpor） Spherical Orbital implant： Experience with 121 Patients

目的评价高密度多孔聚乙烯义眼座（Medpor）眶内植入的疗效及其并发症。方法回顾分析2003年3月至2006年3月期间眶内植入多孔聚乙烯义眼座121例，男性91例，女性30例，平均年龄29岁（6～53岁）。其中眼球摘除术后Ⅰ期植入20例，眼球内容剜除术后Ⅰ期植入54例，Ⅱ期植入47例。结果随诊时间6～36个月，平均随访时间18个月。121例均取得满意效果，结膜创口愈合好，义眼座无脱出，无暴露及感染。义眼座植入眼眶后活动度较好，所配带的义眼外观满意。结论Medpor义眼座眶内植入可明显地矫正眼窝凹陷，可采用自体巩膜包裹或者直接眶内植入，术后义眼座活动度好，并发症少。是一种理想的眶内植入物材料。

Objective To assess the clinical effect and the complication of the porous polyethylene （PP） orbital implant （Medpor） in the reconstruction of the anopthalmia.Methods A retrospective analysis of cases series of 121 patients in whom a porous polyethylene was implanted after evisceration or unwrapped after nucleation between March 2003 and March 2006.Results There were 91 male and 30 female prtients studied. The average age of the patiengs was 29 years（range 6 to 53 years）. The mean follow-up was 18 months（range, 6 months to 36 months）. Implants were placed after evisceration in 54 cases with autologous sclera covering the anterior implant. PP implamts were placed unwrapped in 20 cases of enucleation and 47 cases of secondary implant. There was no case of conjunctiva dehiscence, implant exposure, implant extrusion or orbital cellulitis. Conclusion The results of this study show the PP orbital implant to provide excellent motility of the artificial eye and good cosmesis with a low rate of complications when used wrapped or unwrapped as a primary and as a secondary implant.
