Abstract
Objective To investigate the features of upper airway appearance and the position of hyoid bone in mixed dentition children with skeletal class Ⅲ malocclusion.Methods Thirty children in mixed dentition (cervical vertebral maturation 7-11 years) with skeletal class Ⅲ malocclusion,and 30 normal children were included in this study.Cephalometric radiographs were taken for the children.The width of the upper airway and the position of the hyoid bone were measured by using Winceph 8.0 software.The width of each part airway and the position of hyoid bone between the two groups were compared.Results Compared with normal children,the width of each part upper airway in skeletal class Ⅲ malocclusion ones was markedly narrowed (t =2.035-4.578,P＜0.05),the width of the soft palate increased (t =2.389,P＜0.05),and the position of hyoid bone located more anteriorly (t=2.583,2.696;P＜0.05).Conclusion There are characteristic changes in the appearance of upper airway and the position of hyoid bone in mixed dentition children with skeletal class Ⅲ malocclusion.关键词
