The position of hyoid bone and atlas vertebra in 29 established mouth breathers (17 boys and 12 girls) in the age group of 10-14 years were cephalometrically evaluated and compared with 23 nose breathers (11 boys and 12 girls). The children of both the groups were selected on the basis of history and clinical examination. The comparisons were made using univariate analysis for male and female groups separately as well as combined. It was observed that mouth breathers do maintain an extended head posture, which was evident from a decrease in distance between the occiput and dorsal arch of atlas vertebra. However the results of the present study did not reveal any distinct characteristics of hyoid bone and atlas vertebra that can be used to predict or associate the craniofacial pattern of mouth breathers.
对29名年龄在10至14岁的已确诊口呼吸者（17名男孩和12名女孩）的舌骨和寰椎位置进行了头影测量评估，并与23名鼻呼吸者（11名男孩和12名女孩）进行了比较。两组儿童均根据病史和临床检查进行选择。分别对男性和女性组以及合并组进行单变量分析以进行比较。观察到口呼吸者确实保持头部伸展姿势，这从枕骨与寰椎背弓之间距离的减小可以明显看出。然而，本研究结果并未揭示舌骨和寰椎的任何明显特征可用于预测或关联口呼吸者的颅面模式。
