摘　　要：为了解下颌前伸式止鼾器对阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)的治疗效果,通过CT影像数据建立OSAHS患者上气道三维模型。运用计算流体动力学方法对其上气道三维模型进行数值模拟仿真,分析OSAHS患者在佩戴止鼾器前后上气道内流体动力学的变化,利用CFD-post对仿真结果进行后处理。研究表明:在OSAHS患者佩戴止鼾器后,上气道结构形态发生变化,下颌前伸式止鼾器能够扩大OSAHS患者上气道体积,改变患者上气道内空气的流速与压力,对患者睡眠时的鼾声减小有一定帮助。To investigate the therapeutic effect of mandibular protrusive anti-snoring device on obstructive sleep apnea-hypopnea syndrome,a three-dimensional model of the upper airway of OSAHS patients is established based on CT images.Computational fluid dynamics method is employed to simulate the three-dimensional model of the upper airway,analyze the changes of fluid dynamics in the upper airway of OSAHS patients before and after using the anti-snoring device CFD-post is employed to post-process the simulation results.The research results show that the upper airway structures of OSAHS patients change after they wear anti-snoring devices,and the mandibular protrusive anti-snoring device can expand the upper airway volume of OSAHS patients,reduce the air flow rate and pressure in the upper airway,and help the patients to reduce their snoring.
