咀嚼肌功能与颅面生长发育之间存在着相互作用，这一观点已被广泛接受。在成年人中，面部尺寸和下颌肌横截面积之间以及面部尺寸和咬肌厚度之间存在相关性。人类咀嚼肌在不同年龄阶段的生长及其与面部尺寸的关系尚不清楚。在329个克里克人，年龄7-22岁，咬肌厚度测量超声。肌肉厚度与年龄、身高、体重和面部尺寸有关，这些都是通过人类学卡尺测量的。将男性和女性分为三个年龄组后，通过单变量方差分析对肌肉厚度进行统计学评估。通过多变量方差分析评估面部尺寸，年龄被认为是协变量。肌肉厚度与面部尺寸的关系进行逐步多元回归分析。咬肌厚度随着年龄的增长，在两种性别。左侧和右侧之间没有发现差异。对于每个年龄组（并校正身高和体重），男性的咬肌明显比女性厚（p < 0.01）。肌肉大小和面部尺寸的变化主要与年龄、身高和体重的变化一致。肌肉厚度与前面部高度、下颌骨长度呈显著负相关，与下颌骨间隙宽度、颧面部宽度呈显著正相关。版权所有（C）1996 Elsevier Science Ltd.
It is widely accepted that an interaction exists between masticatory muscle function and craniofacial growth. In adults, correlations have been found between facial dimensions and jaw-muscle cross-sectional area, and between facial dimensions and masseter muscle thickness. Little is known about growth of the human masticatory muscles and its relation with facial dimensions at different ages. In 329 Creek individuals, aged 7-22 yr, masseter muscle thickness was measured by ultrasonography. Muscle thickness was related to age, stature and weight, and to facial dimensions, measured by means of anthropological calipers. Muscle thickness was statistically assessed by univariate analysis of variance, after the males and females had been divided into three age groups. Facial dimensions were assessed by multivariate analysis of variance, age being considered as a covariate. The relation between muscle thickness and facial dimensions was subjected to stepwise multiple regression analysis. Masseter muscle thickness increased with age in both sexes. No differences were found between the left- and right-hand side. For each age group (and corrected for stature and weight), males had significantly thicker masseters than females (p < 0.01). Variation in muscle size and facial dimensions mainly coincided with variation in age, stature and weight. Apart from these, muscle thickness showed a significantly negative relation with anterior facial height and mandibular length, and a significantly positive relation with intergonial width and bizygomatic facial width.
