Abstract
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.
