After a short review of our method, we compared the results of the radiographs of 18 cases of CdLS to the results of our normal material. All of our normal statistical data was obtained from AP and lateral view radiographs at a distance of 1 m, in the prevailing conditions of everyday practice in a radiological department. We studied quantitative changes such as microcephaly and brachycephaly, and for the first time we introduced qualitative changes such as occipital rotation and the study of obliquity of the foramen magnum (line BAO). We found microcephaly in all our cases of CdLS and brachycephaly in only 72%. Furthermore, we found a lack of positive occipital rotation in all our cases of CdLS and the line BAO turned posteriorly with O higher than BA. The same conditions were observed on our normal material only in an early postnatal stage.
在简要回顾我们的方法之后，我们将18例CdLS患者的X光片结果与我们正常样本的结果进行了比较。我们所有的正常统计数据均来自放射科日常工作中在1米距离处拍摄的前后位和侧位X光片。我们研究了小头畸形和短头畸形等定量变化，并且首次引入了枕骨旋转和枕骨大孔倾斜度（BAO线）研究等定性变化。我们发现所有CdLS病例均存在小头畸形，而短头畸形仅占72%。此外，我们发现所有CdLS病例均缺乏枕骨正向旋转，且BAO线向后扭转，O高于BA。仅在出生后早期阶段，我们的正常样本中观察到了相同情况。
