OBJECTIVE
To explore the correlation between hyoid bone (HB) positions and facial growth patterns (facial patterns) in Chinese adults; to identify any significant difference in HB position among subjects with different facial patterns in various dental ages.
METHODS
Lateral cephalometric radiographs of 197 Chinese subjects were divided into nine groups based on their dental ages and facial patterns. Seven measurements were used to define HB position. Regression, correlation analyses, and one-way ANOVA were carried out.
RESULTS
Significant correlations were found between facial patterns and anteroposterior HB positions. The HB was more anterior in the horizontal group after mixed dentition and further away from the mandibular plane in the vertical group of adults. Vertical HB positions were insignificantly different in any stage.
CONCLUSION
HB position and facial patterns were correlated. There were significantly different HB positions among people with different facial patterns in various dental ages.
目的
探讨中国成年人舌骨（HB）位置与面型生长模式（面型）之间的相关性；确定不同牙龄不同面型受试者 HB 位置的差异。
方法
根据牙龄和面型将 197 名中国受试者的侧位头颅侧位片分为 9 组。采用 7 项测量指标来定义 HB 位置。进行回归、相关分析和单因素方差分析。
结果
面型与 HB 的前后位置存在显著相关性。混合牙列期水平组 HB 更靠前，成人垂直组 HB 距下颌平面更远。任何阶段垂直 HB 位置均无显著差异。
结论
HB 位置和面型相关。不同牙龄不同面型的人 HB 位置存在显著差异。
