摘　　要：面部对称性评价是正畸、口腔、整形外科等研究颜面部美观相关学科所关注的热点。尽管国内外学者借助各种新兴技术与手段开展了很多有关颜面对称性评价的研究,但由于其内容和方法的复杂性以及个人评价的主观性,目前颜面不对称的评判仍尚未建立统一的标准。颜面不对称涉及面部长宽高三个方向的改变,属复杂的牙颌面畸形,其早期发现及精确评价尤为重要,临床上除了必要的牙颌面检查,还需配合相应的辅助手段来评价颜面不对称。本文通过对目前常用的三维评价方法进行总结归纳,按照评价手段将颜面不对称评价方法分为三维测量的定性分析、定量分析、动态分析、数理分析、人工智能分析等5大类方法。通过分析总结各类方法的临床应用特点、优势及局限性,发现虽然每种方法的精确度、评价范围、诊断性质、计算方法等均有不同,但随着三维测量技术的不断发展,三维评价方法将会越来越客观、精准、便捷,成为评价颜面部不对称的主流方法。Facial symmetry evaluation has always been a hot topic of concern for doctors who engage in the study of facial beauty disciplines such as orthodontics,dentistry,and plastic surgery.Although scholars at home and abroad have carried out much research on the evaluation of facial symmetry with a variety of emerging technologies and methods,there is still a lack of unified standards for the evaluation of facial asymmetry due to the complexity of the content and methods and individual subjectivity.Facial asymmetry involves changes in the length,width and height of the face.It is a complex dental and maxillofacial malformation whose early identification and accurate evaluation are particularly im⁃portant.Clinically,in addition to the necessary dental and maxillofacial examinations,it is also necessary to evaluate fa⁃cial asymmetry with the help of corresponding auxiliary methods.This paper gives a summary of the commonly used three⁃dimensional evaluation methods.The evaluation methods of facial asymmetry can be divided into 5 categories:qualitative analysis,quantitative analysis,dynamic analysis,mathematical analysis,and artificial intelligence analysis.After the analysis and summarization of the characteristics,advantages and limitations of each method in clinical appli⁃cations,it is found that although these methods vary in accuracy,evaluation scope,diagnosis nature and calculation method,etc.,the three⁃dimensional evaluation methods are more objective,more accurate and more convenient and will become the mainstream evaluation method for facial asymmetry with further development of three⁃dimensional measure⁃ment technologies.
