Relação entre métrica e beleza na cirurgia plástica – revisão sistemática sobre a proporção áurea na face

Abstract

RELATION BETWEEN METRICS AND BEAUTY IN PLASTIC SURGERY – SYSTEMATIC REVIEW OF THE FACIAL GOLDEN PROPORTION Beauty has a fundamental importance in cosmetic plastic surgery. To evaluate an individual's facial beauty, we most take into account aspects like: the psychosocial context in which he is inserted and the face harmony, that relies on the metric relationship between your main elements. Among the ratios, we will study the golden proportion, that is a association between three points considered by many as the mathematical representation of beauty and harmony. The objective of this study is to analyze the association between the existence of golden proportion in facial measures and its relationship with beauty perception. This systematic review was made through the data collected from scientific papers published on national and international journals, without year restriction, written in portuguese and english. The articles were found through the following search engines: PUBMed, Science Direct, Google Scholar, Scielo and BVS, using the keyword, in portuguese and english, connected with the boolean operators "and" and "or". The search was made by two researchers and the results were analyzed for verification of the relevance through the abstracts and the full text. After the exclusion,16 articles remained to be included in this study. Accordingly to theirs results, the studies evaluated a variety of populations, including the evaluation of 61 countries by only one article. However, it was noted a preference for the feminine faces, being studied 881 women and only 474 men, despite the importance of an equal evaluation between the genders; besides a lack of padronization of the facial landmarks used in each article, making it difficult to compare the obtained results. Concerning golden proportion and its relationship with beauty, this review sorted the articles in two groups: the first with the studies that sorted the faces in attractives and not attractives, comparing the presence of the golden proportion, being more important than the second group, that only analyzed the presence of this ratio in the attractive faces. As conclusion, even without the agreement between the articles, most of then didn't find a relationship between facial beauty and the golden proportion.
