目的通过计算机纤维喉镜下mller’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mller’s检查;将52例OSAHS患者与正常人mller’s检查结果进行比较,同时将52例OSAHS患者mller’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。mller’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mller’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 To evaluate the value of fiberopharyngoscopy in the diagnosis of OSAHS by analyzing the correlation between the results of mller’s examining the upper airway obstruction plane and the indexes of polysomnography. Methods Fifty-two patients with OSAHS and 15 normal subjects underwent polysomnography (PSG) and mller’s examination under computerized fiberoptic laryngoscopy. Fifty-two patients with OSAHS were compared with mller’s test results of normal subjects and 52 Cases of OSAHS patients mller’s examination of pharyngeal cavity collapse degree and its PSG test indicators AHI, LSaO2 correlation analysis. Results There was significant difference in the minimum cross-sectional area of the velopharyngeal between OSAHS patients and normal controls (P <0.05), while the smallest cross-sectional area of the glossopharynx was not statistically significant (P> 0.05). However, difference. m ller’s check pharyngeal cavity collapse degree and respiratory disturbance index AHI was positively correlated, that is, the maximum collapse of the pharynx, the smaller the cross-sectional area, the greater the collapse, the higher the AHI, the more severe respiratory disorders, and pharyngeal collapse And the lowest oxygen saturation LSaO2 no significant correlation. Conclusion The mller’s method under fibrolaryngoscope can not only reflect the severity of OSAHS, but also intuitively observe the location and degree of upper airway collapse, providing the basis for the selection of surgical procedures.
