【摘要】 目的:观察肥厚性鼻炎患者鼻声反射参数:鼻腔最小横截面积(NMCA)、鼻腔容积(NCV)、鼻腔最小横截面积至前鼻孔的距离(DCAN)和鼻阻力(NR)的改变。方法:应用声反射鼻测量计(eccovision型)对30例主诉有鼻阻塞的肥厚性鼻炎患者及10例前鼻镜检查正常的志愿受试者进行测试。结果:DCAN:试验组:1.52±0.07cm,对照组:2.13±0.09cm两者之间有显著性差异(P<0.05);NMCA:试验组:0.39±0.06cm2,对照组:0.62±0.13cm2两者之间有极显著性差异(P<0.01);NCV:试验组:13.12±2.17cm3,对照组:15.10±0.35cm3两者之间有显著性差异(P<0.05);NR:试验组:5.83±1.24cmH2O/L/Min,对照组:1.18±0.55cmH2O/L/Min,两者之间有极显著性差异(P<0.01)。结论:NMCA对鼻气道阻力的产生具有明显影响,可作为判断鼻腔通畅度、鼻甲肥厚程度,手术部位及手术疗效提供参考依据。更多还原

【Abstract】 Objective:To observing the site of nasal parameters:nasal minimal cross-sectional area(NMCA),nasal cavity volume(NCV),distance of the minimal cross-section area to the notril(DCAN) and nasal resistance(NR).Method:30 cases of hypertrophic rhinitis with nasal obstraction and 10 cases normal volunteer were tested by eccovision acoustic rhinometry.Result:DCAN:Testing group:1.52±0.07cm,Contrast:2.13±0.09cm,P<0.05;NMCA:Testing group:0.39±0.06cm2,Contrast:0.62±0.13 cm2,P<0.01;NCV:Testing group:13.12±2.17cm3,Contrast:15.10±0.35 cm3P<0.05;NR:Testing group:5.83±1.24 cmH2O/L/Min,Contrast:1.18 ±0.55 cmH2O/L/Min,P<0.01.Conclusion:NMCA had an effect to NR,it could be judged the degree of nasal unobstructed and the thicking of nasal turbinate,and it could be based on operational locus and effect.更多还原
