阻鼾器治疗轻中度阻塞性睡眠呼吸暂停综合征前后上气道CT的研究

目的通过计算机体层摄影(CT)观察轻、中度阻塞性睡眠呼吸暂停综合征(OSAS)患者戴用阻鼾器前后上气道形态的变化,并与正常对照组比较,探讨阻鼾器治疗OSAS的机制。方法经夜间多导睡眠仪(PSG)监测确诊为OSAS的轻、中度患者20例,患者正常戴用阻鼾器1～3个月后分别行未戴阻鼾器时和戴着阻鼾器时CT扫描,并对对照组行CT扫描,获取资料。结果OSAS患者上气道腔比对照组狭窄,戴用阻鼾器后各层面径线、面积均增大。结论OSAS患者上气道腔存在结构性狭窄,戴用阻鼾器后使其上气道结构趋于正常。

Computed tomography study on upper airway before and after treatment of light or mild obstructive sleep apnea syndrome by snoreguard

Objective To study the upper airway structural change of snoreguard for obstructive sleep apnea syndrome(OSAS) by computed tomography.Methods 20 cases of light or mild OSAS were treated with snoreguard.After 1-3 months,CT examinations were conducted for the patients,with and without the snoreguard respectively.And CT examinations were conducted for the comparing groups.Results The OSAS patients' upper airway was stricturer than that of the comparing groups.After wearing the snoreguard,the section areas and the distances of the airway were increased.Conclusion Structural stricture exists in the cavity of the upper airway of the OSAS patients,and the upper airway structure became normal after wearing snoreguard.
