Medpor板修复眼眶骨折合并眼球内陷的临床观察

目的：观察高密度多孔聚乙烯( Medpor )板在眼眶骨折合并眼球内陷修复术中的应用效果。
　　方法：对因眼眶骨折致眼球内陷患者17例17眼,采用Medpor板进行眶壁骨折修复手术。术后随访6mo,观察眼球突出度、眼球运动及复视等变化。
　　结果：术前患眼较对侧平均内陷(3.4±1.5) mm,术后6mo有2例残存眼球内陷1mm,其余15例眼球突出度与健眼差值小于1 mm。术前17例均存在眼球运动受限并伴有不同程度复视,术后6mo,16例患者眼球运动受限治愈,复视消失,1例患眼轻度外展受限并残存外侧水平复视。术后随访期间未见Medpor板的脱出、排斥、感染或其他不良反应。
　　结论：Medpor板可有效补充眼眶容积,修复眼球内陷等眼眶骨折并发症。

Clinical observation of Medpor porous polyethylene implants in treatment of enophthalmos combined with orbital fracture

AIM: To observe the efficacy of Medpor porous polyethylene implants in treatment of enophthalmos combined with orbital fracture.

METHODS: Seventeen cases(17 eyes)with enophthalmos caused by orbital fracture underwent surgical treatment with Medpor porous polyethylene implants. All accepted a 6-mo follow-up and the data of enophthalmos, eyeball movement and diplopia were collected.

RESULTS: The average difference of exophthalmos between damaged eyes and undamaged eyes was(3.4±1.5)mm preoperatively, two cases had residual 1mm enophthalmos 6mo after surgery, while other 15 cases were completely corrected. Seventeen cases suffered from eyeball movement restriction and diplopia preoperatively, 16 cases had normal eyeball movement without diplopia 6mo after surgery, 1 case with limitation of abduction and horizontal diplopia. There was no extrusion, rejection, infection or other complications occurred during follow-up.

CONCLUSION: Medpor porous polyethylene implants can effectively improve the orbit volume to repair enophthalmos caused by orbital fracture.
