Changes in nasal airflow caused by varying intranasal volumes and cross-sectional areas affect the contact between air and surrounding mucosa entailing alterations in nasal air conditioning. This study evaluates the correlation between nasal air conditioning and the volumes of the inferior and middle turbinates as measured by magnetic resonance imaging (MRI).
Fourteen healthy volunteers were enrolled. Each volunteer had been examined by rhinomanometry, acoustic rhinometry, intranasal air temperature, and humidity measurements at defined intranasal sites as well as MRI of the nasal cavity and the paranasal sinuses. The volumetric data of the turbinates was based on the volumetric software Amira.
Comparable results were obtained regarding absolute humidity values and temperature values within the nasal valve area and middle turbinate area for both the right and the left side of the nasal cavity. No statistically significant differences were found in the rhinomanometric values and the acoustic rhinometry results of both sides (p > 0.05). No statistical correlations were found between the volumes of the inferior (mean, 6.1 cm3) and middle turbinate (mean, 1.8 cm3) and the corresponding humidity and temperature values. Additionally, the air temperature and humidity values did not correlate with the rhinometrical endonasal volumes (0-20 mm and 20-50 mm from the nasal entrance).
The normal range of volumes of the inferior and middle turbinate does not seem to have a significant impact on intranasal air conditioning in healthy subjects. The exact limits where alterations of the turbinate volume negatively affect nasal air conditioning are still unknown.
鼻内体积和横截面积的变化所引起的鼻气流改变，会影响空气与周围黏膜之间的接触，进而导致鼻腔空气调节功能的改变。本研究评估通过磁共振成像（MRI）测量的下鼻甲和中鼻甲体积与鼻腔空气调节之间的相关性。
招募了14名健康志愿者。每位志愿者均接受了鼻阻力测量、鼻声反射测量、特定鼻内部位的鼻内空气温度和湿度测量，以及鼻腔和鼻窦的MRI检查。鼻甲的体积数据基于容积软件Amira。
鼻腔左右两侧的鼻瓣区和中鼻甲区域内的绝对湿度值和温度值得到了相似的结果。两侧的鼻阻力测量值和鼻声反射测量结果均未发现统计学上的显著差异（p>0.05）。下鼻甲（平均6.1 cm³）和中鼻甲（平均1.8 cm³）的体积与相应的湿度和温度值之间未发现统计学相关性。此外，空气温度和湿度值与鼻阻力测量的鼻内体积（距鼻入口0-20 mm和20-50 mm）也没有相关性。
在健康受试者中，下鼻甲和中鼻甲的正常体积范围似乎对鼻腔空气调节没有显著影响。鼻甲体积改变对鼻腔空气调节产生负面影响的确切界限仍不清楚。
