The purpose of this study was to establish the norms of soft-tissue profile analysis for a sample of Japanese-Brazilian adults.
Facial-profile photographs were taken of 60 Japanese-Brazilians (30 men, 30 women) with normal occlusions and balanced faces, ranging in age from 18 to 30 years. The facial-profile variables were measured by computerized means and compared with white norms by using the independent t test.
Statistically significant differences were found in the Japanese-Brazilian sample compared with the white norms. Japanese-Brazilian women had more anteriorly positioned glabellae, smaller nasal projections, and more opened nasolabial angles than white American women. Japanese-Brazilian men had more anteriorly positioned glabellae, smaller noses, larger protrusions of the upper and lower lips, less projected B'-points, and more obtuse nasolabial angles than white American men.
A single norm for facial-profile esthetics does not apply to all ethnic groups. The normative data for the Japanese population should be used as a guide for comparison during diagnosis, and the orthodontist and the maxillofacial surgeon should also consider each patient's perception of beauty, to establish an individualized treatment plan.
本研究的目的是为巴西日裔成年人样本建立软组织侧貌分析的标准。
对60名年龄在18至30岁之间、咬合正常且面部匀称的巴西日裔（30名男性，30名女性）拍摄面部侧貌照片。通过计算机手段测量面部侧貌变量，并使用独立t检验与白人标准进行比较。
与白人标准相比，巴西日裔样本存在统计学上的显著差异。巴西日裔女性的眉间位置比美国白人女性更靠前，鼻突更小，鼻唇角更开阔。巴西日裔男性的眉间位置比美国白人男性更靠前，鼻子更小，上下唇突出度更大，B'点突出度更小，鼻唇角更钝。
单一的面部侧貌美学标准并不适用于所有种族群体。日本人群的标准数据应作为诊断过程中比较的指导，正畸医生和颌面外科医生还应考虑每位患者的审美观念，以制定个性化的治疗方案。
