It has been suggested that asymmetries in the morphological properties of the face contribute to or produce asymmetries in facial emotional expression. Over 50 years of research on hard tissue, soft tissue, and facial surface asymmetries is reviewed here. Generally, it appears that if consistent asymmetry characterizes facial morphology, it is extremely small in magnitude or characterizes regions yet to be examined. In contrast, marked homology and asymmetry in regional size and area has been noted often. At present, it does not appear that asymmetry in facial morphology is associated with facial expressive asymmetry, with the latter more likely to be an outcome of functional brain asymmetry.
有人提出，面部形态特征的不对称会导致或产生面部表情的不对称。本文回顾了50多年来关于硬组织、软组织和面部表面不对称性的研究。一般来说，如果面部形态存在一致的不对称性，其程度极小，或者仅存在于有待研究的区域。相比之下，区域大小和面积的显著同源性和不对称性却经常被提及。目前，面部形态的不对称似乎与面部表情的不对称并无关联，后者更有可能是大脑功能不对称的结果。
