OBJECTIVE
We sought to investigate the pattern, duration, and amplitude of nasal cycle and its response to nasal decongestant.
STUDY DESIGN AND SETTING
Ten adult volunteers attended 2 sessions (with and without nasal spray of 0.1% xylometazoline) for consecutive examinations by rhinomanometry and acoustic rhinometry every 10 minutes over 6 hours.
RESULTS
A spontaneous fluctuation in nasal minimum cross-sectional area, volume, and nasal resistances (inspiration and expiration) could be observed in every consecutive measurement. A significant negative correlation (r = -0.33 to -0.70, P < 0.05) between both nasal passages was shown in 5 subjects by rhinomanometry and in 2 subjects by acoustic rhinometry but was not detectable after nasal spray with 0.1% xylometazoline.
CONCLUSION
A spontaneous fluctuation in nasal patency can be documented every 10 minutes with irregular pattern, frequency, and amplitude. Classic nasal cycle is not a universal phenomenon, which can be abolished by the application of decongestant.
目的
我们试图研究鼻周期的模式、持续时间和幅度及其对鼻减充血剂的反应。
研究设计与设置
10名成年志愿者参加了2次检查（一次使用0.1%赛洛唑啉鼻喷雾剂，一次不使用），在6小时内每隔10分钟通过鼻阻力计和鼻声反射仪进行连续检查。
结果
在每次连续测量中，均可观察到鼻腔最小横截面积、容积和鼻阻力（吸气和呼气）的自发波动。通过鼻阻力计，5名受试者的双侧鼻腔之间显示出显著的负相关（r = -0.33至-0.70，P < 0.05）；通过鼻声反射仪，2名受试者显示出显著负相关，但在使用0.1%赛洛唑啉鼻喷雾剂后未检测到这种相关性。
结论
鼻腔通畅度每10分钟会出现一次自发波动，其模式、频率和幅度不规则。典型的鼻周期并非普遍现象，使用减充血剂可消除该现象。
