We describe a patient who sustained a blowout fracture of the superior orbital roof without an orbital rim fracture. The initial CT study (obtained with 10-mm-thick sections) did not show herniation of the intraorbital fat into the anterior cranial fossa; however, thin (3-mm-thick) direct orbital sections showed a fracture of the midportion of the superomedial orbital roof with displacement of the fracture fragment into the anterior cranial fossa.
我们描述了一名患者,其发生了眶顶上方爆裂性骨折,而眶缘无骨折。最初的CT检查(采用10毫米厚的层面)未显示眶内脂肪疝入前颅窝;然而,薄层(3毫米厚)直接眼眶层面显示眶顶内上中部骨折,骨折碎片移位至前颅窝。
