OBJECTIVE
To evaluate the craniofacial characteristics of the Class II malocclusion patients with mouth-breating by posteroanterior cephalometry.
METHODS
To measure craniofacial width of the 12 Class II malocclusion patients with mouth-breathing, and to compared these measures with corresponding measures in a group of normal children.
RESULTS
The width of the maxillary base bone (J-J) was less than that in normal children significantly (P < 0.01). The mouth-breathing children's upper and lower arch width (at first molar and cuspid) were comparatively narrower, and lateronasal width (Lap-Lap) was narrower too.
CONCLUSION
Mouth breathing may lead to craniofacial morphological abnormal development in craniofacial transverse structures.
目的
通过头影测量法评估Ⅱ类错牙合伴口呼吸患者的颅面特征。
方法
测量12例Ⅱ类错牙合伴口呼吸患者的颅面宽度，并与一组正常儿童的相应测量值进行比较。
结果
上颌基骨宽度（J-J）明显小于正常儿童（P<0.01）。口呼吸儿童的上下牙弓宽度（第一磨牙和尖牙处）相对较窄，鼻外侧宽度（Lap-Lap）也较窄。
结论
口呼吸可能导致颅面横向结构的形态异常发育。
