项目摘要

The aim of this study was to evaluate whether substantial airflow changes occur by changing both jaw position and body posture in normal subjects and patients with obstructive sleep apnea (OSA).15 normal controls (9 males and 6 females) and 15 male OSA patients participated in this study. All subjects were measured their maximum forced inspiratory flow (FIF_<25-75>) curve in seven positions as follows; a.0% jaw forward-upright position, b. 0% jaw forward-supine position, c.50% jaw forward-supine position, d.75% jaw forward-supine position, e.0% jaw forward-lateral position, f.50% jaw forward-lateral position, g.75% jaw forward-lateral position.Although FIF_<25-75> was increased by changing the body posture from supine to lateral in normal subjects, it wasn't increased by increasing the jaw forward position of them. On the other hand, the more jaw position forward, the more FIF_<25-75> increased in OSA patients. But it wasn't increased by changing the body posture of them. There were no significant differences between 50% forward and 75% forward jaw position in both groups.In normal subjects, change of jaw position was more effective than that of body posture for FIF_<25-75>. However in OSA patients, change of body posture was more effective than that of jaw position for FIF_<25-75>. It was suggested that the treatment effect in 50% forward position was similar in 75% forward position.

本研究的目的是评估正常受试者和阻塞性睡眠呼吸暂停 (OSA) 患者的下颌位置和身体姿势的改变是否会发生显着的气流变化。 15 名正常对照者（9 名男性和 6 名女性）和 15 名男性 OSA 患者参与在这项研究中。所有受试者均在以下七个位置测量了最大用力吸气流量（FIF_<25-75>）曲线； a.0% 下巴向前直立位置，b. 0% 下巴前倾仰卧位，c.50% 下巴前倾仰卧位，d.75% 下巴前倾仰卧位，e.0% 下巴前倾侧向位置，f.50% 下巴前向侧向位置，g. 75% 下颌前倾-侧卧位置。虽然正常受试者将身体姿势从仰卧改为侧卧会增加 FIF_<25-75>，但增加下颌前倾位置并不会增加 FIF_<25-75>。另一方面，OSA患者下颌位置越前倾，FIF_<25-75>增加得越多。但它并没有通过改变他们的身体姿势而增加。两组下颌位置50%前倾和75%前倾之间无显着差异。在正常受试者中，下颌位置的改变比身体姿势的改变对FIF_<25-75>更有效。然而，在 OSA 患者中，对于 FIF_<25-75>，改变身体姿势比改变下颌位置更有效。研究表明，50%前倾位的治疗效果与75%前倾位的治疗效果相似。
