本研究旨在评价成人面部不对称的颅底和上下颌结构的形态特征，以确定下颌不对称是由原始下颌畸形还是受颅底畸形的影响。42例成人牙面畸形患者根据下颌偏斜度分为两组：不对称组(n=24)和非不对称组(n=18)。将它们与使用3D可视化和分析程序的三维(3D)CT重新格式化图像进行比较。对两组间的差异、颅底不对称与上颌骨不对称的相关性进行统计学评价，不对称组与非不对称组颅底不对称程度无统计学差异。研究发现，不对称的髁状突位置与颅底特征有关。然而，髁突和颅底的3D位置与下颌不对称并不密切相关。结果表明，颅骨测量变量并不是决定面部不对称程度的主导因素，下颌骨本身的功能或内在的不对称生长潜能可能补偿或加剧了生长期内颅骨不对称的影响。
This study intended to evaluate the morphological characteristics of the cranial base and maxillomandibular structures of facial asymmetry in adult patients, so as to determine whether mandibular asymmetry is a result of primary mandibular deformity or if it is influenced by cranial base deformity.Forty-two adult patients with dentofacial deformity were placed into two groups according to the deviation of the chin: Asymmetry group (n = 24) and Non-asymmetry group (n = 18). They were compared with three-dimensional (3D) CT reformatted images using a 3D visualization and analyzing program. The differences between the two groups, the correlation between the cranial base and maxillomandibular asymmetry were evaluated statistically.The degree of cranial base asymmetry in the Asymmetry group was not statistically different from the Non-asymmetry group. The asymmetric condyle position was found to be associated with skull base characteristics. The 3D position of the condyle and cranial base, however, was not closely related with mandibular asymmetry. The results showed that the cranial measurement variables were not the dominant factors that determined the degree of facial asymmetry.It seems that the mandibular skeletal factors itself, functional or intrinsic asymmetric growth potential, compensate or aggravate the influence of cranial asymmetry during the growth period.
