The purpose of this study was to compare the difference of craniofacial morphology between oral and nasal breathing children, and discover the relationship between respiratory mode and craniofacial morphology.
Using the system for the simultaneous measurement of oral and nasal respiration, 34 oral breathing children and 34 nasal breathing children aged from 11 to 14 years were selected.
Compared with the nasal-breathing children, the oral-breathing children showed apparently vertical growth pattern. The mandibuler plane Angle of oral breathing children is 39.3, which is significant greater than that of nasal breathing children (P < 0.01). The jans, the oral-breathing children had shorter mandibular body, larger gonion angle, retrusive chin and face (P < 0.05). On the other hand, in the sagittal direction, the oral breathing children may display all kinds of skeletal facial types. There is no significant difference between the two groups.
Oral breathing is one of the factors related to the vertical over-development.
本研究旨在比较口呼吸儿童与鼻呼吸儿童颅面形态的差异，探讨呼吸模式与颅面形态之间的关系。
采用口鼻呼吸同步测量系统，选取34名11至14岁的口呼吸儿童和34名鼻呼吸儿童。
与鼻呼吸儿童相比，口呼吸儿童呈现出明显的垂直生长模式。口呼吸儿童的下颌平面角为39.3，显著大于鼻呼吸儿童（P < 0.01）。此外，口呼吸儿童的下颌体较短，下颌角较大，颏部后缩，面部后缩（P < 0.05）。另一方面，在矢状方向上，口呼吸儿童可能表现出各种骨骼面型。两组之间无显著差异。
口呼吸是导致垂直过度发育的相关因素之一。
