Acoustic rhinometry is used to objectively measure the minimal cross sectional area and volumes of nasal cavities. However, no data for healthy subjects has been reported in Macedonia. Therefore, we wanted to establish the normal range among healthy adults and to evaluate the changes after nasal decongestion.
We included 50 males and 50 females in this study (mean age: 23.2 years; age range: 19 to 40 years). An acoustic rhinometer was used to evaluate the first minimal cross-sectional area (MCA1), the distance from the tip of the probe to the first minimal cross-sectional area (D1), the second minimal cross sectional area (MCA2), the distance from the tip of the probe to the second minimal cross sectional area (D2), the volume between the tip of the nosepiece and 3 cm into the nasal cavity (V03), the volume of the nasal cavity between 2 to 5 cm from the tip of the nosepiece (V25), the volume of the nasal cavity between 4 to 7 cm from the tip of the nosepiece (V47), and the volume between the tip of the nosepiece and 7 cm into the nasal cavity (V07). These measurements were taken before and after nasal decongestion.
Data acquired from the male group before decongestion were as follows: MCA1 L: 0.71+/-0.07 (cm2); D1 L: 0.34+/-0.05 (cm); MCA2 L: 0.46+/-0.13 (cm2); D2 L: 2.46+/-0.11 (cm); MCA1 R: 0.73+/-0.06 (cm2); D1 R: 0.35+/-0.05 (cm); MCA2 R: 0.47+/-0.11 (cm2); D2 R: 2.41+/-0.18 (cm); V03 L 2.59+/-0.82 (cm3); V25 L; 4.83+/-1.93 (cm3); V47 L; 7.82+/-2.94 (cm3); V07 L: 11.48+/-4.23 (cm3); V03 R 2.55+/-0.72 (cm3); V25 R; 4.71+/-1.76 (cm3); V47 R; 7.60+/-2.30 (cm3); V07 R: 12.03+/-3.65 (cm3); data acquired from the female group before decongestion were: MCA1 L: 0.65+/-0.12 (cm2); D1 L: 0.35+/-0.05 (cm); MCA2 L: 0.50+/-0.12 (cm2); D2 L: 2.36+/-0.15 (cm); MCA1 R: 0.65+/-0.11 (cm2); D1 R: 0.35+/-0.04 (cm); MCA2 R: 0.49+/-0.13 (cm2); D2 R: 2.41+/-0.13 (cm); V03 L 2.64+/-0.58 (cm3); V25 L; 5.11+/-1.17 (cm3); V47 L; 8.30+/-2.20 (cm3); V07 L: 12.38+/-3.19 (cm3); V03 R 2.42+/-0.56 (cm3); V25 R; 4.43+/-1.34 (cm3); V47 R; 7.35+/-2.29 (cm3); V07 R: 11.06+/-3.19 (cm3) The increase in MCA1 and MCA2 after nasal decongestion was significant (p<0.001), both in females and males. The increases in V03, V25, V47 and V07 after nasal decongestion were statistically significant both in the female and male groups as well (p<0.001).
Acoustic rhinometry is a convenient method for assessing the geometry of the nasal cavity. The maximal effect of decongestion is found in the anterior and middle parts of the nasal cavity, at the level of the inferior and middle turbinates.
鼻声反射测量法用于客观测量鼻腔的最小横截面积和容积。然而，马其顿尚未有关于健康受试者的数据报道。因此，我们希望确定健康成年人的正常范围，并评估鼻减充血后的变化。
本研究纳入50名男性和50名女性（平均年龄：23.2岁；年龄范围：19至40岁）。使用鼻声反射仪评估第一个最小横截面积（MCA1）、探头尖端到第一个最小横截面积的距离（D1）、第二个最小横截面积（MCA2）、探头尖端到第二个最小横截面积的距离（D2）、鼻托尖端到鼻腔内3厘米处的容积（V03）、鼻托尖端2至5厘米之间的鼻腔容积（V25）、鼻托尖端4至7厘米之间的鼻腔容积（V47）以及鼻托尖端到鼻腔内7厘米处的容积（V07）。这些测量在鼻减充血前后进行。
男性组减充血前的数据如下：左MCA1：0.71±0.07（平方厘米）；左D1：0.34±0.05（厘米）；左MCA2：0.46±0.13（平方厘米）；左D2：2.46±0.11（厘米）；右MCA1：0.73±0.06（平方厘米）；右D1：0.35±0.05（厘米）；右MCA2：0.47±0.11（平方厘米）；右D2：2.41±0.18（厘米）；左V03：2.59±0.82（立方厘米）；左V25：4.83±1.93（立方厘米）；左V47：7.82±2.94（立方厘米）；左V07：11.48±4.23（立方厘米）；右V03：2.55±0.72（立方厘米）；右V25：4.71±1.76（立方厘米）；右V47：7.60±2.30（立方厘米）；右V07：12.03±3.65（立方厘米）；女性组减充血前的数据为：左MCA1：0.65±0.12（平方厘米）；左D1：0.35±0.05（厘米）；左MCA2：0.50±0.12（平方厘米）；左D2：2.36±0.15（厘米）；右MCA1：0.65±0.11（平方厘米）；右D1：0.35±0.04（厘米）；右MCA2：0.49±0.13（平方厘米）；右D2：2.41±0.13（厘米）；左V03：2.64±0.58（立方厘米）；左V25：5.11±1.17（立方厘米）；左V47：8.30±2.20（立方厘米）；左V07：12.38±3.19（立方厘米）；右V：2.42±0.56（立方厘米）；右V25：4.43±1.34（立方厘米）；右V47：7.35±2.29（立方厘米）；右V07：11.06±3.19（立方厘米）。鼻减充血后，女性和男性的MCA1和MCA2均显著增加（p<0.001）。鼻减充血后，女性和男性组的V03、V25、V47和V07增加也具有统计学意义（p<0.001）。
鼻声反射测量法是评估鼻腔几何形态的便捷方法。减充血的最大效果出现在鼻腔的前部和中部，即下鼻甲和中鼻甲水平。
