目的:探讨16层螺旋 CT 在骨性泪道骨折诊断中的应用价值。方法:回顾分析经临床证实的65例骨性泪道骨折患者的16层螺旋 CT 图像。采用美国 GE 公司 AW 4.1工作站对图像进行后处理,行多平面重建术(MPR),比较薄层横断面与多平面重组图像的诊断结果。结果:16层螺旋 CT 图像能清晰显示泪囊窝、鼻泪管骨折,65例患者共计75处骨折,均为复合性骨折,多为鼻眶筛区域骨折,其中上颌骨额突骨折45例(70%),泪骨骨折30例(46%),伴发筛板骨折40例(62%),鼻骨骨折32例(49%),额骨鼻突骨折13例(20%),鼻颌缝分离23例(36%),鼻额缝分离17例(26%),额颌缝分离20例(30%),泪颌缝分离50例(78%),鼻骨间缝分离26例(40%)。薄层横断面与多平面重组图像对骨性泪道骨折的诊断准确性无显著差异。结论:16层螺旋 CT 能准确、细致地显示骨性泪道骨折的部位、程度及伴发改变。
目的:探討16層螺鏇 CT 在骨性淚道骨摺診斷中的應用價值。方法:迴顧分析經臨床證實的65例骨性淚道骨摺患者的16層螺鏇 CT 圖像。採用美國 GE 公司 AW 4.1工作站對圖像進行後處理,行多平麵重建術(MPR),比較薄層橫斷麵與多平麵重組圖像的診斷結果。結果:16層螺鏇 CT 圖像能清晰顯示淚囊窩、鼻淚管骨摺,65例患者共計75處骨摺,均為複閤性骨摺,多為鼻眶篩區域骨摺,其中上頜骨額突骨摺45例(70%),淚骨骨摺30例(46%),伴髮篩闆骨摺40例(62%),鼻骨骨摺32例(49%),額骨鼻突骨摺13例(20%),鼻頜縫分離23例(36%),鼻額縫分離17例(26%),額頜縫分離20例(30%),淚頜縫分離50例(78%),鼻骨間縫分離26例(40%)。薄層橫斷麵與多平麵重組圖像對骨性淚道骨摺的診斷準確性無顯著差異。結論:16層螺鏇 CT 能準確、細緻地顯示骨性淚道骨摺的部位、程度及伴髮改變。

Objective:To explore the clinical value of 16-slice spiral CT in diagnosing bony lacrimal passage fracture.Methods:16-slice spiral CT images of 65 patients,which were clinically proved as bony lacrimal passage fractures,were analyzed retro-spectively.Postprocessing of images was performed by GE AW 4.1.Multi planar reconstruction(MPR).The thin-thick axial images were compared with the MPR.Results:16-slice spiral CT showed clearly the fractures of lacrimal sac fossa and nasolac-rimal duct.All the 65 cases were compound fracture,most of which were naso-orbital-ethmoid fracture,including 45 cases of fractures of the frontal process of the maxilla,30 cases of the lacrimal bone fractures,40 cases of ethmoid bone fractures on the medial orbital wall,32 cases of nasal bone fractures,13 cases of the nasal process fractures of frontal bone,23 cases with naso-maxillary suture separations,17 cases with naso-frontal suture separations,20 cases with frontal-maxillary suture separations, 50 cases with lacrimo-maxillary suture separations,26 cases with internasal suture separations.There was no significant difference between the thin-thick axial images and the MPR in diagnosing bony lacrimal passage fracture.Conclusions:16-slice spiral CT can accurately display the location,extent and secondary changes of bony lacrimal passage fracture in detail.
