| 中文摘要:目的探讨鼻声反射（AR）用于鼻腔截面积测量的准确性。方法对10例(20侧)成人正常鼻腔行螺旋CT和鼻声反射检测，CT重建层面与鼻腔声波传导弧线垂直。比较两种检测方法的面积－距离曲线，并进行统计学分析。结果CT和鼻声反射对鼻瓣区检测结果直线相关和回归分析r＝0.885（P＜0.01，CT＝0.17＋0.82AR）。距前鼻孔6.0cm内的相关性（r＝0827，P＜0.01）比6.0cm以后（r＝0.352，P＜0.01）高。距前鼻孔6.0cm以后至鼻咽部，鼻声反射对截面积评测过高。结论鼻声反射测量能准确提供距前鼻孔6.0cm内的距离－面积信息，对距前鼻孔6.0cm以后评测过高，更适用于距前鼻孔60cm内的测量。 |

| Abstract:ObjectiveTo evaluate the accuracy of acoustic rhinometry(AR) in estimating nasal airway cross-sectional areas by computed tomography (CT). MethodsTwenty normal nasal passages of 10 adults were examined by AR and CT. Actual cross-sectional areas of the nasal cavity were determined from CT sections perpendicular to the curved acoustic axis of the nasal passage. The area-distance curves derived from both methods were compared. ResultsLinear regression analysis revealed a reasonable agreement of AR and CT in the nasal valve（ r＝0.885，P＜0.01，CT＝0.17＋0.82AR）. The correlation between AR and CT in the anterior part of the nasal cavity below 6.0cm distance from the nostrils（r＝0.827，P＜0.01）revealed a better reasonable agreement than in the posterior part（r＝0.352，P＜0.01）. Beyond 6.0cm to choana, AR overestimated cross-sectional area. ConclusionAR is a reasonably accurate method for measuring area-distance in the anterior part of the nasal cavity，and the overestimation of cross-sectional area occurs in the posterior nose. |
