  • 简介:目的:眶颧复合体骨折后眼球内陷的手术矫正方法及其疗效。方法:回顾性分析1999.01/2006—05我院眼科收治的45例眶颧复合体骨折合并眼球内陷患者行骨折复位和眼眶重建的手术资料和随访结果。其中早期手术11例,晚期手术34例。通过眉弓外侧切口、下睑切口、前庭沟切口和冠状切口联合人路,在建立良好咬合关系的基础上,恢复和加强眶颧复合体正常解剖结构,微型钛板坚强内固定,Medpor充填修复眶壁骨折矫正眼球内陷。45例患者术后随访12~30mo。结果:所选45例患者术后外观获得显著改善,眼球内陷矫正,复视得到改善。早期手术病例组骨折复位和功能恢复均优于晚期组。结论:眶颌颧复合体骨折手术可以恢复正常面中部外形、矫正眼球内陷和改善复视症状。早期手术更容易达到解剖复位,提高疗效。

  • 简介:目的:观察早期衰老大鼠视网膜色素上皮-光感受器细胞复合体超微结构的变化。方法:取3月龄及12月龄大鼠视网膜,制成半薄切片,透射电镜下观察视网膜色素上皮-光感受器细胞复合体超微结构的变化。结果:12月龄大鼠视网膜中出现视网膜色素上皮细胞(retinalpigmentepithelium,RPE)凋亡和RPE-光感受器细胞复合体的退行性改变。结论:视网膜色素上皮-光感受器细胞复合体的退行性改变是视网膜衰老的早期表现。
