The aim of this work was to perform a cephalometric analysis of the craniofacial parameters and natural head posture of mouth-breathers compared with control subjects, and to study the relationship between nose-breathing and the vertical dimension.
The headfilms taken at start of treatment of 53 cases (28 girls, 25 boys) aged 9 to 30 who consulted the dento-facial orthopedic department of the Ibn Rochd Casablanca dental consultation and treatment center were studied.
Among the mouth-breathers, we noted mandibular retrusion (SNB) in association with posterior rotation and more pronounced tilt of the mandibular plane (PP-MP) compared with the controls (P<0.05), a disproportionate increase in anterior face height and a lessening of posterior face height (hyperdivergence). These increases in anterior face height are often associated with retrognathism (and open bite).
Our study has shown that there are cephalometric differences between mouth-breathers and nose-breathers. There are several studies in the literature with results that support ours. Collaboration between the pediatric dentist, the orthodontist and the ENT specialist is important so as to establish an early diagnosis of mouth-breathing in children and initiate appropriate treatment to recreate the best conditions for harmonious development.
本研究旨在对口呼吸者的颅面参数和自然头位进行头影测量分析，并与对照组进行比较，同时研究鼻呼吸与垂直维度之间的关系。
对伊本·鲁西德卡萨布兰卡牙科咨询与治疗中心牙颌面正畸科就诊的53例年龄在9至30岁之间的患者（28名女孩，25名男孩）治疗开始时拍摄的头颅侧位片进行研究。
与对照组相比，口呼吸者中我们发现下颌后缩（SNB），伴有下颌平面后旋及更明显的倾斜（PP-MP）（P<0.05），前牙面高不成比例增加而后牙面高减小（高度离散）。这些前牙面高的增加常与下颌后缩（及开咬）相关。
我们的研究表明，口呼吸者与鼻呼吸者在头影测量上存在差异。文献中有多项研究结果支持我们的结论。儿科牙医、正畸医生和耳鼻喉科专家之间的合作对于早期诊断儿童口呼吸并开展适当治疗以创造和谐发育的最佳条件非常重要。
