BACKGROUND
We studied the affect of an adhesive external nasal dilator strip (ENDS) on the inspiratory nasal airflow. A prospective study was performed.
METHODS
Twenty-two healthy volunteers were enrolled in the study. All volunteers analyzed the inspiratory nasal sound samples before and while wearing a commercially available ENDS. This nasal sound analysis includes the spectral analysis and average sound intensities in low frequency (Lf), medium frequency (Mf), and high frequency (Hf).
RESULTS
In the sound analyses, an increase was found in sound intensity at Hf when the nasal strips were not worn whereas a decrease was found in sound intensity at Hf when the nasal strips were on.
CONCLUSION
Changes in the nasal geometry of the anterior part of the nose by wearing nasal strips affects the pattern of nasal airflow and transforms it into a laminar pattern.
背景
我们研究了一种粘性外鼻扩张器（ENDS）对吸气性鼻气流的影响。进行了一项前瞻性研究。
方法
研究纳入了 22 名健康志愿者。所有志愿者在佩戴市售 ENDS 前后分析吸气性鼻音样本。这种鼻音分析包括频谱分析以及低频（Lf）、中频（Mf）和高频（Hf）的平均声音强度。
结果
在声音分析中，当不佩戴鼻夹时，Hf 处的声音强度增加，而当佩戴鼻夹时，Hf 处的声音强度降低。
结论
通过佩戴鼻夹改变鼻前部的鼻腔几何形状会影响鼻气流模式，并将其转变为层流模式。
