目的探讨多层螺旋CT对眼眶内侧壁(主要是筛骨纸样板)骨折的临床应用价值。方法对52例筛骨纸板骨折的病例进行回顾性分析,行轴位CT容积扫描并多轴面重建。结果纸样板内陷40例,纸样板断裂并内陷20例,成角错位5例,断裂但仍保持弧形形态2例,合并内直肌肿胀增粗20例,眶内脂肪疝入23例,眶内积气17例,筛窦积液38例。结论多层螺旋CT能准确显示筛骨纸样板骨折的直接和间接征象,并能根据具体影像学表现对其进一步分型,了解周围软组织结构的情况,对配合临床的治疗有极大诊断学意义。
Objective To investigate the clinical value of multi-slice spiral CT in the diagnosis of fractures of medial orbital wall (mainly stencil paper). Methods Fifty-two cases of fracture of ethmoidal cartilage were retrospectively analyzed. Axial CT volume scanning and multiaxial reconstruction were performed. Results The paper sample was invaded in 40 cases. The paper sample was ruptured and invaded in 20 cases. There were 5 cases of angular dislocation, 2 cases of fracture but still in arc shape, 20 cases of rectus abdominis swelling and thickening, 23 cases of orbital fat hernia , Orbital pneumothorax in 17 cases, 38 cases of ethmoid effusion. Conclusion MSCT can accurately show the direct and indirect signs of fracture of the ethmoid mesh model, and can be further subdivided according to the specific imaging findings to understand the surrounding soft tissue structure, with the clinical diagnosis of great diagnostic significance .
