Why do the craniofacial bones grow asymmetrically in patients with plagiocephaly (unilateral coronal synostosis)? We obtained three-dimensional skeletal replicas of two patients with the condition and analysed the deformities of the facial bones. From this analysis we deduced that the asymmetric deformation of the facial bones in these patients was caused by a combination of three rotations: rotation of the calvaria toward the affected side because of premature synostosis of the coronal and sphenofrontal sutures; rotation of the facial bones on the horizontal plane toward the unaffected side caused by anterior displacement of the TM (temporomandibular)-joint on the affected side; and downward rotation of the facial bones toward the unaffected side caused by inferior displacement of the TM-joint on the affected side.
为什么斜头畸形（单侧冠状缝早闭）患者的颅面骨会不对称生长？我们获取了两名患有该病症患者的三维骨骼复制品，并分析了面部骨骼的畸形情况。通过该分析我们推断，这些患者面部骨骼的不对称变形是由三种旋转的组合引起的：由于冠状缝和蝶额缝过早闭合，颅骨向患侧旋转；患侧颞下颌关节向前移位导致面部骨骼在水平面上向未受影响侧旋转；患侧颞下颌关节向下移位导致面部骨骼向未受影响侧向下旋转。
