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. Our outline-based classification method is described, using the software programs OsiriX, MeVisLab, and Matlab. These programs were used to identify chosen landmarks (porion and exocanthion), create a base plane and a plane at 4\u00a0cm, segment outlines, and plot resulting graphs. We measured repeatability and reproducibility, and mean curves of groups were analyzed. All raters achieved excellent intraclass correlation scores (0.994\u20131.000) and interclass correlation scores (0.989\u20131.000) for identifying the external landmarks. Controls, scaphocephaly, trigonocephaly, and brachycephaly all have the peak of the forehead in the middle of the curve (180<jats:italic>\u00b0<\/jats:italic>). In contrary, in anterior plagiocephaly, the peak is shifted (to the left of graph in right-sided and vice versa). 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.<\/jats:p><jats:p><jats:italic>Conclusion<\/jats:italic>: 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.<jats:table-wrap><jats:table><jats:tbody>\n<jats:tr>\n<jats:td colspan=\"2\"><jats:bold>What is Known:<\/jats:bold><jats:italic>\u2022 Diagnosis of craniosynostosis is relatively simple; however, classification of craniosynostosis is difficult and current techniques are not widely applicable.<\/jats:italic><\/jats:td>\n<\/jats:tr>\n<jats:tr>\n<jats:td colspan=\"2\"><jats:bold>What is New:<\/jats:bold><jats:italic>\u2022 We introduce a novel technique for classification of skull deformities due to craniosynostosis, an objective and reproducible methodology using CT scans resulting in characteristic curves.
