摘要： 目的 通过测定不同鼻通气量硬腭上表面的压强,分析口呼吸对腭盖下降及错𬌗畸形影响的机制。方法 利用锥形束计算机断层扫描（CBCT）数据和有限元相关软件重建1名健康志愿者的上气道及鼻腔三维模型,并修复空洞、平滑模型、网格划分后进行不同呼吸方式下的边界条件设定和数值模拟。结果 成功建立健康人鼻呼吸上气道模型及鼻腔模型,获取了鼻呼吸的吸、呼两相上气道及不同截面的压力云图和不同鼻通气量吸、呼两相压力云图,计算得到不同鼻通气量时硬腭上表面的压强。结论 随着鼻通气量的减小,吸气相气流对硬腭上表面压强逐渐增大,呼气相气流对硬腭上表面压强逐渐减小。二者均逐渐接近大气压。吸、呼两相鼻腔内压强梯度均逐渐减小。

Abstract: Objective This study aims to analyze the mechanism of the effect of mouth breathing on hard palate descent and malocclusion by measuring the pressure of the upper surface of the hard palate with different nasal ventilation.Methods The three-dimensional models of the upper airway and nasal cavity of the healthy volunteer were reconstruc-ted by using cone beam computed tomography data and finite element software. The boundary conditions and numerical simulations were set under different breathing patterns after repairing the cavities, smoothing the model, and meshing.Results The upper airway and nasal cavity models of the healthy volunteer were established. Moreover, the pressure distribution cloud maps of inspiratory and expiratory of nasal breathing at different cross-sections of the upper airway and those of different nasal ventilation were obtained. The pressure on the upper surface of the hard palate with different nasal ventilation was also calculated.Conclusion With the decrease of nasal ventilation, the pressure of inspiratory airflow on the upper surface of the hard palate increased gradually, whereas that of expiratory decreased gradually. Both were getting closer to atmospheric pressure. The pressure gradient in the nasal cavity of inspiratory and expiratory decreased gradually.
