Implementation of the Utrecht Cranial Shape Quantificator (UCSQ) classification method on 3D photogrammetry in patients with different types of craniosynostosis is the aim of the present study. Five children (age <1 year) of every group of the common craniosynostoses (scaphocephaly, brachycephaly, trigonocephaly, right-sided and left-sided anterior plagiocephaly) were randomly included. The program 3-Matic (v13.0) was used to import and analyze the included 3dMD photos. Three external landmarks were placed. Using the landmarks, a base plane was created, as well as a plane 4 cm superior to the base plane. Using UCSQ, we created sinusoid curves of the patients, the resulting curves were analyzed and values were extracted for calculations. Results per patient were run through a diagnostic flowchart in order to determine correctness of the flowchart when using 3D photogrammetry. Each of the patients (n=25) of the different craniosynostosis subgroups is diagnosed correctly based on the different steps in the flowchart. This study proposes and implements a diagnostic approach of craniosynostosis based on 3D photogrammetry. By using a diagnostic flowchart based on specific characteristics for every type of craniosynostosis related to specific skull deformities, diagnosis can be established. All variables are expressed in number and are therefore objective.
本研究的目的是在不同类型颅缝早闭患者中，将乌得勒支颅骨形状量化器（UCSQ）分类方法应用于三维摄影测量。每组常见颅缝早闭（舟状头、短头、三角头、右侧和左侧前斜头）随机纳入5名年龄小于1岁的儿童。使用3-Matic（v13.0）程序导入并分析纳入的3dMD照片。放置三个外部标志点。利用这些标志点创建一个基准平面，以及一个位于基准平面上方4厘米的平面。使用UCSQ，我们创建了患者的正弦曲线，对所得曲线进行分析并提取值进行计算。将每位患者的结果通过诊断流程图，以确定使用三维摄影测量时流程图的正确性。根据流程图中的不同步骤，不同颅缝早闭亚组的每位患者（n = 25）均被正确诊断。本研究提出并实施了一种基于三维摄影测量的颅缝早闭诊断方法。通过使用基于与特定颅骨畸形相关的每种颅缝早闭类型的特定特征的诊断流程图，可以建立诊断。所有变量均以数字表示，因此是客观的。
