The general skull morphology of the head of the Cavalier King Charles Spaniel (CKCS) was examined and compared with cephalometric indices of brachycephalic, mesaticephalic, and dolichocephalic heads. Measurements were taken from computed tomography images. Defined landmarks for linear measurements of were identified using three-dimensional (3D) models. The calculated parameters of the CKCS were different from all parameters of mesaticephalic dogs but were the same as parameters from brachycephalic dogs. However, the CKCS had a wider braincase in relation to length than in other brachycephalic breeds. Studies of the etiology of the chiari-like malformation in the CKCS should therefore focus on brachycephalic control groups. As Chari-like malformation has only been reported in brachycephalic breeds, its etiology could be associated with a higher grade of brachycephaly, meaning a shorter longitudinal extension of the skull. This has been suggested for other breeds.
对骑士查理王小猎犬（CKCS）头部的一般颅骨形态进行了检查，并与短头型、中头型和长头型头部的头影测量指标进行了比较。测量取自计算机断层扫描图像。使用三维（3D）模型确定了用于线性测量的明确地标。CKCS的计算参数与中头型犬的所有参数不同，但与短头型犬的参数相同。然而，CKCS的脑壳相对于长度比其他短头型品种更宽。因此，对CKCS中类似Chiari畸形病因的研究应集中在短头型对照组。由于类似Chiari畸形仅在短头型品种中报道过，其病因可能与更高等级的短头畸形有关，即颅骨的纵向延伸较短。其他品种也有过这样的推测。
