摘要
目的探讨螺旋CT及多种后处理技术对眼眶壁骨折患者的诊断及骨折修复术中的指导价值。方法回顾性分析2010年10月至2013年11月河南省焦作市人民医院眼科收治的86例(86只眼)眶内壁骨折患者的临床资料。采用64层螺旋CT机对患者进行薄层扫描,并利用容积再现技术和多平面重建技术对眶内骨折患者进行重建诊断,以MEDPOR及羟基磷灰石人工骨片为填充材料,对86例眼眶骨折患者实施眶壁骨折整复术。结果多平面重建技术能清晰显示眶内软组织嵌顿及疝出状态,容积再现技术可显示眶壁骨折空间立体结构。经过3个月至2年的术后随访,52例眼球内陷的患者中眼球内陷完全矫正者45例(86.5%),眼球内陷部分矫正者7例(13.5%)。62例复视患者中,复视完全消失者39例(62.9%),复视基本消失者20例(32.2%),较术前加重者3例(4.9%)。结论螺旋CT及多种后处理技术能帮助医生在术前全面了解患者眶内骨折的位置和范围,有助于更好地诊断和治疗眶内骨折。
Objective To evaluate the clinical significance of spiral CT and post-processing techniques in the diagnosis and prosthesis of orbital wall fracture caused by ocular trauma.Methods The clinical data of 86 patients ( 86 eyes ) with orbital wall fracture who received care in the Department of Ophthalmology,the People′s Hospital of Jiaozuo,Henan,China between October 2010 and November 2011 were retrospectively analyzed.All patients underwent surgical repair of orbital wall fracture with microporous high-density polyethylene implant ( MEDPOR ) filled with hydroxyapatite after 64-thin slice spiral CT scanning and the reconstructive diagnosis through the volume rendering technique and multi-planar reconstruction ( MPR) technique.Results The MPR image clearly revealed the soft tissue incarceration and the status of hernia on the orbital floor,and the volume rendering technique adequately showed the three-dimensional structure of the orbital fracture.During the postoperative follow-up ( range from 3 months to 2 years), 45 (86.5%) injured eyes were completely corrected and 7 (13.5%) were partly corrected.In the 62 patients with diplopia, 39 ( 62.9%) achieved an excellent outcome ( complete disappearance of diplopia) ,20 ( 32.2%) achieved a good outcome ( almost complete disappearance of diplopia ) , but 3 (4.9%)experienced a significant lesion aggravation,after operation.Conclusion Spiral CT and the various available post-processing techniques are very helpful to ophthalmologists in the preoperative investigations of the location and extent of orbital wall fracture and thereby may significantly impact the diagnosis and treatment of orbital wall fracture.
