Craniosynostosis is usually diagnosed upon clinical judgment (medical history and physical examination, including anthropometry) and is confirmed by radiographic imaging.Ĭlassification of skull shape deformities is essential and could allow for type and severity to be classified and thus may aid in clinical as well as research applicability to evaluate presentation, development, and treatment. In craniosynostosis patients, one or more sutures have prematurely fused to form a solid bone connection, resulting in a restriction of expansion of the cranial vault, normal growth of the brain, and deformation of the calvaria. In normal skull development, the cranial sutures allow the brain to expand as the infant matures. Additionally, controls, scaphocephaly, and trigonocephaly have a high peak of the forehead scaphocephaly has the lowest troughs in brachycephaly, the width/frontal peak ratio has the highest value with a low frontal peak.Ĭonclusion: We introduced a preliminary study showing an objective and reproducible methodology using CT scans for the analysis of craniosynostosis and potential application of our method to 3D photogrammetry. In contrary, in anterior plagiocephaly, the peak is shifted (to the left of graph in right-sided and vice versa). ![]() Controls, scaphocephaly, trigonocephaly, and brachycephaly all have the peak of the forehead in the middle of the curve (180 °). All raters achieved excellent intraclass correlation scores (0.994–1.000) and interclass correlation scores (0.989–1.000) for identifying the external landmarks. We measured repeatability and reproducibility, and mean curves of groups were analyzed. These programs were used to identify chosen landmarks (porion and exocanthion), create a base plane and a plane at 4 cm, segment outlines, and plot resulting graphs. Our outline-based classification method is described, using the software programs OsiriX, MeVisLab, and Matlab. We included 5 children of every group of the common craniosynostoses (scaphocephaly, brachycephaly, trigonocephaly, and right- and left-sided anterior plagiocephaly) and additionally 5 controls. We present a novel technique for classification of skull deformities due to most common craniosynostosis. ![]()
