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.

不同种族人群正常咬合情况下呼吸道的头颅测量对比研究。

研究目的本研究旨在比较白人、黑人、日本人、日裔巴西人和黑人高加索人的鼻咽和口咽气道尺寸：将 216 例未经治疗的巴西年轻受试者（平均年龄 12.94 岁；SD 0.88）的侧位X光片样本分为五组：黑人高加索人、黑人、高加索人、日本人和日裔巴西人。侧位X光片用于测量口咽（从软腭中点到咽前壁最近点）和鼻咽（从舌后缘与下颌骨下缘交点到咽后壁最近点）。进行方差分析（ANOVA）和Tukey检验（P< 0.05）：结果：不同种族群体的口咽线性尺寸相似。高加索人的鼻咽线性维度明显大于高加索黑人和黑人：结论：所有群体的颊咽部数值相似。结论：所有群体的颊咽部数值相似，但高加索人的数值明显高于高加索黑人和黑人。
