纤维喉镜下müller's检查在OSAHS诊断中的价值

The value of computer fiber optic pharygoscopy with Muller's maneuver in diagnosis of obstructive sleep apnea hypopnea syndrome

目的通过计算机纤维喉镜下mller's检查上气道阻塞平面的结果与多导睡眠监测指标进行相关性分析,评价纤维喉镜在OSAHS定位诊断中的应用价值。方法对52例OSAHS患者及15名正常人分别进行多导睡眠监测(PSG)及计算机纤维喉镜下mller's检查;将52例OSAHS患者与正常人mller's检查结果进行比较,同时将52例OSAHS患者mller's检查的咽腔塌陷度与其PSG检查指标AHI、LSaO2进行相关分析。结果OSAHS患者和正常人腭咽最小截面积差异有统计学意义(P<0.05),而舌咽最小截面积无统计学意义(P>0.05);但腭、舌咽塌陷度在两组间有差异。mller's检查的咽腔塌陷度与呼吸紊乱指数AHI呈正相关,即咽腔最大程度塌陷时截面积越小,塌陷度越大,则AHI越高,呼吸紊乱程度越严重,而咽腔塌陷度与最低血氧饱和度LSaO2尚无明显相关关系。结论纤维喉镜下mller's检查法不仅可以反应OSAHS的严重程度,还可以直观地观察到上气道塌陷的部位和程度,为外科手术的选择提供依据。

Objective analyze the correlation between the obstructive abnormalities of upper airway that examined by computer fiber optic pharygoscopy with Muller＇s maneuver（CFPMM） and outcomes of polysomnography （PSG）. Methods fifty-six patients with obstructive sleep apnea hypopnea syndrome（OSHAS） and fifteen patients without it both underwent the examination of CFPMM and PSG, compare the outcomes of each group, meanwhile studied tbe correlation between the pharyngeal collapsibility of fifty-six patients with OS-AHS and PSG outcomes that included apnea and hypopnea index（ AHI）, SpO2, etc. Results pharyngeal collapsibility, which examined by CFPMM were associated with increased rates of AHI（ P 〈 0. 05 ）. Conclusion CFPMM not only can reflect the severity of OSAHS, but also directly observe the content and location of pharyngeal eollapsibility.
