眼眶骨折眼球内陷功能性复位手术的临床观察

目的：研究眼眶骨折眼球内陷手术复位的方法和手术最佳时期，探讨手术前后视功能变化。方法：应用螺旋CT影像和视觉电生理检查技术对100例施行眼眶重建和眼球复位手术的患者进行观察研究。结果：在早期手术的40例患者中，28例眼球内陷完全复位，12例改善；60例晚期手术中，32例完全复位，28例得到部分改善；手术前后视网膜电流图（F—ERG）和视觉诱发电位（P-VEP）无显著性差异。结论：采用人工材料行眼眶重建和眶内充填技术手术治疗眼球内陷可获得满意的疗效，早期手术效果优于晚期手术，手术创伤对视功能无明显影响，眼眶重建和眼球复位手术是安全可行的。

Clinic studies on functional repositioning operation of enophthalmos of orbital fractures

Objective To studay the best time and method of reconstruction of orbit and enophthalmos,and the influence on visual fuction. Methods 100 cases with enophthalmos and orbital fracture were operated,and examinated by using the computed tomography (CT),flash electroretinogram(F-ERG) and pattern visual evoked potentials (P-VEP) before and after operation. Results 28 cases was completely recoveried in 40 early cases,12 cases had improved. In late cases,32 of 60 cases was completely recoveried,28 cases had improved. No significant difference was found in examination of F-ERG and P-VEP before and after operation. Conclution Rconstruction of the orbit and repositioning of enophthalmos of orbital fractures can obtain satisfactory result,and early repairing is better than late repairing. There is no impairment in reconstrction of the orbit and reposition of enophthalmos of orbital fractures,which is an safe and effective surgical technique.
