Aim:
This study analyses pathomorphological and physiological head shapes and classifies the path morphology in positional plagiocephaly and brachycephaly.
目的:
分析病理学形态和生理学头部形态,并将病理学形态分为位置性斜头和短头。


Patients and methods:
78 infants with a positional plagiocephaly (5.99 months) and 32 infants with a positional brachycephaly (6.53 months) with a Cephalic index>94% were investigated in this study and compared to a matched control group of 35 infants. The head shapes were analyzed by stereophotogrammetry 3D data.
病患与方法:
这项研究中调查78个婴儿:位置性偏头(平均月龄:5.99个月)和32个婴儿的位置短头(平均月龄:6.53个月),头颅指数(CI)>94%,并与匹配的对照组35个婴儿进行比较。采用三维立体摄影测量数据分析头部形状,生成了每个婴儿整个头部的3D数据。

Results:
The cephalic index, the total width, and coronal circumference were the highest values in patients with brachycephaly and the lowest values in the control group. The asymmetry of the head showed that the diagonal difference in brachycephalic patients more than doubled, and in patients with plagiocephaly almost tripled compared to the controls. A significantly higher total volume and vertex height was found for the patients with plagiocephaly and the patients with brachycephaly compared to the controls.
结果:
短头症患者的头颅指数、总宽度和冠状缝围度值最高,对照组最低。头部的不对称表明,短头症患者的对角线差异是对照组的两倍多,斜头症患者的对角线差异几乎是对照组的三倍。与对照组相比,斜头畸形患者和短头畸形患者的总容积和顶高明显更高。


Conclusion:
The cephalic index is a valuable and reliable parameter in order to differentiate positional deformities from unaffected skulls. Path morphology of a plagiocephaly is associated with the most severe asymmetry of the head. Plagiocephaly and brachycephaly overlap in several criteria. Therefore it seems justified to speak of a continuum rather than to differentiate between plagiocephaly and brachycephaly.
结论:
我们的三维分析表明,当用于区分位置性畸形和未受影响的颅骨时,头指数是一个有价值和可靠的参数。斜头畸形的病理形态学与头部最严重的不对称有关,斜头畸形和短头畸形在几个标准上有重叠。因此,讨论他们的关系性更为合理,而不是区分斜头畸形和短头畸形。

相关研究论点:
1、在研究中,采用3D扫描仪,利用五台基于立体摄影测量方法的同步摄像机获取虚拟数据集,只需扫描一次即可生成360°无创数据。
2、在本文中,孩子6个月大时,研究中系统地评估了不同形式的体位畸形,这些畸形是在出生后的第一个月内获得的,并对它们进行了比较。生长相关参数在以前的报告中,短头状头部形状被定义为CI>92%或93%(Hutchison等人,2005年;Schaaf等人,2010年)。结果表明,CI可以作为一个变量来量化正常范围以外的短头头部形状。
