A craniometric study of the C. de Lange syndrome (CdLS).
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.
