摘要
目的：探讨对中重度阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者上气道阻塞部位简便、准确的定位方法,以指导手术治疗。方法：采用Eccovision型鼻、咽声反射测量仪,对50例经PSG监测确诊为OSAHS的患者进行测试,记录鼻腔最小横截面积（NMCA）、鼻腔最小横截面积至前鼻孔的距离（DCAN）、下鼻甲前端截面积（MCA）、鼻阻力（NR）和由鼻前孔向后6 cm内鼻腔容积（NCV）,以及4.8~15.0 cm区段内咽腔的平均截面积和容积;结合影像学和内镜检查,对比分析鼻、咽声反射对判定阻塞部位的阳性率和敏感度。结果：50例中重度OSAHS患者NMCA、DCAN、MCA、NCV、NR依次为（0.61±0.35）cm2、（2.06±0.12）cm、（0.87±0.12）cm2、（9.24±2.31）cm3和（0.51±0.32）kPa/（L.min）;咽部平均截面积和容积明显小于对照组,差异有统计学意义（P〈0.01）。Ⅰ、Ⅱ、Ⅲ型患者最小截面积与前鼻孔的距离分别为（2.06±0.12）cm、（9.50±4.08）cm和（13.10±2.52）cm,与对照组相比差异有统计学意义。结论：鼻、咽声反射测试可以对OSAHS发生的阻塞平面进行简便、准确的判断和分型,以指导手术治疗。
Objective：To explore a simple and accurate method for localization of upper airway obstruction in patients with obstructive sleep apnea-hypopnea syndrome（OSAHS）and provide instructions for surgical treatment.Method：Fifty OSAHS patients confirmed by PSG underwent acoustic rhinometric and pharyngometric assessment by Eccovision.The parameters were recorded,including nasal minimal cross-sectional area（NMCA）,distance of MCA from the nostril（DCAN）,minimum cross-sectional area at the nasal valve（MCA）,nasal resistance（NR） and nasal volume from 0 to 6 cm from the nostril（NCV）,as well as pharyngeal cross-sectional area（CSA）and volume from 4.8 to 15.0 cm.The sensitivity and specitivity of acoustic rhinometry and pharyngometry on localization of airway obstruction was determined by a comprehensive imaging and endoscopic study.Result：In 50 cases with severe OSAHS,NMCA,DCAN,MCA,NCV,NR were（0.61±0.35）cm2,（2.06±0.12）cm,（0.87±0.12）cm2,（9.24±2.31）cm3 and（0.51±0.32）kPa/（L·min）,respectively.Pharyngeal CSA and volume were statistically significantly lower than that in control group（P0.01）.The value of DCAN was（2.06±0.12）cm,（9.50±4.08）cm,（13.10±2.52）cm in typeⅠⅡ,Ⅲ patient,respectively.Compared with the control group,the difference was statistically significant.Conclusion：Acoustic rhinometry and pharyngometry is a simple and safe method in localization of airway obstruction in patients with OSAHS.
