To investigate effects of the nose dilating devices on nasal anatomy and breathing in healthy subjects.
27 healthy subjects were tested when using the Breathe Right nasal strip or the Nozovent dilator. Posterior rhinomanometry, acoustic rhinometry, and a subjective evaluation were used as methods.
Both devices significantly increased the minimum cross-sectional area of the nasal valve and decreased nasal resistance. The Nozovent dilator proved to be significantly more effective in reducing nasal resistance than the Breathe Right nasal strip.
Nose dilating devices, the Breathe Right nasal strip and the Nozovent dilator, can be used to reduce nasal resistance. More studies are needed to evaluate the usefulness of the devices for patients with chronic obstruction for any reason in the valve area.
研究扩鼻装置对健康受试者鼻腔解剖结构和呼吸的影响。
27名健康受试者在使用畅呼吸鼻贴或诺佐文特扩张器时接受测试。采用后鼻测压法、鼻声反射法和主观评估作为检测方法。
两种装置均显著增加了鼻瓣膜的最小横截面积并降低了鼻腔阻力。事实证明，诺佐文特扩张器在降低鼻腔阻力方面比畅呼吸鼻贴更有效。
扩鼻装置，即畅呼吸鼻贴和诺佐文特扩张器，可用于降低鼻腔阻力。对于因任何原因导致瓣膜区慢性阻塞的患者，还需要更多研究来评估这些装置的实用性。
