下颌前伸矫治器对阻塞性睡眠呼吸暂停综合征患者的上气道影响

目的 :探讨二种不同体位下 ,下颌前伸矫治器对阻塞性睡眠呼吸暂停综合征患者的上气道影响。 方法 :经多导睡眠仪监测确诊的 10例OSAS患者戴矫治器前后分别拍摄坐位及仰卧位的头影测量侧位片。 结果 :10例OSAS患者戴入矫治器后 ,下颌骨前伸 ,咽腔结构及周围软硬组织的位置关系均发生相应改变。经多导睡眠仪监测 ,暂停 /低通气指数 (AHI)明显下降 ,从 ( 10 74± 4 3 2 )次 /小时降至 ( 3 65± 3 45 )次 /小时。 结论 :下颌前伸矫治器是治疗轻度OSAS的有效治疗方法 ,在不同体位下均可改变口咽通气道。

The effects on the upper airway of mandibular advancement device treating for obstructive sleep apnea syndrome

Objective:To investigate the feasibility of mandibular advancement device for the treatment of obstructive sleep apnea syndrome (OSAS) and the effects of two body position on the upper airway. Methods: Ten cases with OSAS were diagnosed by overnight polysomnographic and aphalometric analysis with mandibular advancement device in different postures. Results: Following the treatment with mandibular advancement device, the position of mandibular was changed to protrusive one, with corresponding changes in the shape of pharyngeal cavity and the positional relation of it with surrounding soft tissues, among all the 10 cases. Conclusions: Mandibular advancement device is effective for the treatment of OSAS. The dimension of airway was changed by mandibular advancement device in two postures.
