儿童呼吸方式与颅面、气道、牙形态的相关性研究

目的研究儿童呼吸方式与颅面、气道、牙形态的相关性。方法选择72例11～14岁的正畸科初诊患者,使用口鼻气流同步测量仪测量其口、鼻气流比例并计算口呼吸比例,在X线头影测量片和牙模型上测量颅面、气道、牙的形态学指标86项,通过t检验筛选出16项有统计学意义及临床意义的指标,进行多元回归分析(向后法)和简单直线回归分析。结果下面高与全面高之比(ANS-Me/N-Me)、下颌角(Ar-Go-Me)、扁桃体或舌根后缘与咽后壁的最小距离(P-T)、上颌基骨宽度(SHJK)与口呼吸比例的密切程度逐渐降低(P<0.05),多元回归系数分别为3.359,0.012,-0.013,-0.021。结论儿童呼吸方式与颅面形态具有一定相关性。

Correlation between oral airflow ratio and craniofacial, airway and dental morphology

Objective To investigate the correlation between airflow ratio and craniofacial, airway and dental morphology. Methods Seventy-two subjects aged 11 to 14 years were selected. The airflow ratio was measured by the system for the simultaneous measurement of oral and nasal respiration.Eighty-six variables of craniofacial, airway and dental morphology were acquired based on cephalometric films and models, from which 16 significant variables were selected. Multiple regression analysis (backward) and linear regression analysis were carried out in order to acquire morphological variables that had closer correlation with the airflow ratio. Results Four variables were found to have closer correlated association with the airflow ratio (P<0.05), which were ANS-Me/N-Me,Ar-Go-Me,P-T,SHJK orderly and the coefficients were 3.359, 0.012, -0.013 and -0.021 ,respectively. Conclusions Craniofacial morphology was related to the respiratory mode.
