阻塞性睡眠呼吸暂停低通气综合征上气道舌骨位置改变的研究

摘要

Objective To discuss the clinical diagnostic and guiding treatment value of changed positions of hyoid bonein the upper airway of patients with obstructive sleep apnea hypopnea syndrome. Methods 128-slice computed tomography was performed for 52 patients with severe OSAHS and 32normal healthy people to measure thehyoid bone in the upper airway in sober state and Muller maneuver. The correlationsbetweenthese indexes were analyzed under linear relation. Results (1)In comparison of the Muller maneuver with sober state , chinnodules and palatal plane to the hyoid in the OSAHS group were statistically higher than the healthy controlgroup (P < 0.001). (2)The distance of hyoid to chinnodules in the OSAHS group was significantlylonger and greater than that of the healthy control group (P < 0.001).(3)The distance of palatal plane to the hyoid was positively correlated with AHI , while thedistances of palatal plane andchinnodules to the hyoidwere both negatively correlated with MSaO2. Conclusion The changes ofhyoid positionare indicative for the clinical diagnosis and is helpful for the guidance of clinical treatment of OSAHS.%目的：探讨阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者舌骨位置的变化对该病发病机制的影响及指导治疗的价值。方法：采用128层螺旋CT分别对52例重度OSAHS 成年男性行清醒和Muller 试验状态及32例正常人行清醒状态上气道扫描，分别测量舌骨位置，进行统计学分析，并与 AHI、MSaO2进行线性相关分析。结果：与正常组相比，清醒状态OSAHS组颏结节、硬腭平面至舌骨距离较长，差异具有统计学意义（P ＜0．001）。与清醒期相比，Muller状态下OSAHS组颏结节至舌骨距离增加，差异具有统计学意义（P ＜0．001）。硬腭平面至舌骨距离与AHI呈正相关；硬腭平面、颏结节至舌骨距离与MSaO2呈负相关。结论：舌骨位置的改变对OSAHS的发病及病情严重程度具有重要影响，对指导临床治疗有重要意义。
