Abstract：
OBJECTIVE: This study aimed to compare the nasopharynx and oropharynx airway dimensions of Caucasians, Blacks, Japanese, Japanese Brazilians, and Black Caucasians.
METHODS: A sample of 216 lateral radiographs of untreated young Brazilian subjects (mean age of 12.94 years; SD 0.88) were divided into five groups: Black Caucasian, Black, Caucasian, Japanese, and Japanese Brazilian. Lateral radiographs were used to measure the oropharynx (from the midpoint on the soft palate to the closest point on the anterior pharyngeal wall) and the nasopharynx (from the intersection of the posterior border of the tongue and the inferior border of the mandible to the closest point on the posterior pharyngeal wall). Analyses of variance (ANOVA) and Tukey\'s test were performed (p< 0.05).
RESULTS: The linear dimension of the oropharynx was similar among the different ethnic groups. Caucasian individuals presented a significantly greater linear dimension of the nasopharynx than Black Caucasian and Black individuals.
CONCLUSIONS: All the groups had similar buccopharyngeal values. However, Caucasian individuals had significantly higher values when compared to Black Caucasians and Black individuals.

摘要：
目的：本研究旨在比较高加索人的鼻咽和口咽气道尺寸，黑人,日本人,日本巴西人,黑人高加索人
方法：未经治疗的年轻巴西受试者（平均年龄为12.94岁；SD0.88）的216张侧位照片样本分为五组：黑人高加索人，黑色,高加索人,日本人,日本巴西侧位X线片用于测量口咽（从软腭的中点到咽前壁上的最近点）和鼻咽（从舌头的后边界和下颌骨的下边界的交点到咽后壁上的最近点）。进行方差分析(ANOVA)和Tukey检验(p<0.05)。
结果：不同种族之间口咽的线性尺寸相似。高加索人的鼻咽部线性尺寸明显大于黑人和黑人。
结论：所有组的颊咽值相似。然而,与黑人白种人和黑人个体相比，白种人个体的价值明显更高。
