This study assessed the value of three-dimensional CT (3D CT) in the diagnosis of craniosynostosis, and correlated the cranial deformity with the presence of osseous defects in cranial vault's bones. One hundred and two children (55♀ and 47♂) with a clinical suspicion of craniosynostosis, underwent spiral computed tomography with 3D reconstruction using the shaded surface display (SSD) and volume rendering (VR) algorithms. We evaluated the presence of osseous defects in cranial bones in correlation with the type of craniosynostosis and the shape of the cranial vault. 3D CT allowed the evaluation of craniosynostosis in all patients. All patients had combined forms of craniosynostosis. Osseous defects in the bones of cranial vault were found in 56 patients of whom nine had scaphocephaly, eight plagiocephaly and one trigonocephaly. CT of the skull with three-dimensional reconstruction can safely and reliably identify craniosynostoses in children and could be used for the identification of osseous defects in the cranial vault.
本研究评估了三维CT（3D CT）在诊断颅缝早闭中的价值，并将颅骨畸形与颅顶骨骨质缺损情况进行关联分析。102例临床怀疑患有颅缝早闭的儿童（55例女性，47例男性）接受了螺旋计算机断层扫描，并使用表面阴影显示（SSD）和容积再现（VR）算法进行三维重建。我们评估了颅骨骨质缺损情况，并将其与颅缝早闭类型及颅顶形状相关联。3D CT能够对所有患者的颅缝早闭情况进行评估。所有患者均为复合形式的颅缝早闭。56例患者发现颅顶骨存在骨质缺损，其中9例为舟状头畸形，8例为斜头畸形，1例为三角头畸形。三维重建的头颅CT能够安全、可靠地识别儿童颅缝早闭情况，还可用于识别颅顶骨质缺损。
