新生大鼠的双侧咬肌切除术会导致颅骨重量和尺寸减小。这种减少对面部骨骼的总体影响程度比对脑壳的影响更大，尽管在每个区域中，长度尺寸比高度或宽度受到更大程度的影响。这种对比不依赖于体重的变化。
去除两侧颞肌（咀嚼肌肉组织的较小组成部分）除了增加脑壳宽度外，颅骨比例几乎没有变化。
这些发现首先可能与脑壳和面部骨骼生长时间的对比有关，其次与肌肉功能下降的程度有关。
Bilateral masseterectomy in newly-born rats results in a diminution in cranial weight and size. Such reduction affects the facial skeleton to a greater overall extent than the braincase, although in each region it is the dimensions of length that are affected to a greater extent that are those of height or width. Such contrasts are not dependent upon changes in body weight.
Removal of both temporal muscles—a smaller component of the masticatory musculature—results in little change in cranial proportions other than an increase in width of the braincase.
Such findings can be related, first, to contrasts in the timing of growth in the braincase and facial skeleton and, second, to the extent to which muscular function is reduced.
