The nasal cycle has been demonstrated in man using several techniques, including magnetic resonance imaging, anterior rhinoscopy, rhinomanometry, all of which have limitations due to expense, discomfort, limited scope or poor reproducibility. Acoustic rhinometry is a new technique which analyses nasal geometry throughout the nasal cavity, not just at the flow-limiting segment. Six adult volunteers were examined at 15-to 30-min intervals using acoustic rhinometry. The classical alternating cycle was seen in three subjects, a non-classical cycle was seen in two, and no cycle seen in one subject. Changes occurred throughout the nasal cavity and corresponded with fluctuations in subjective scores of obstruction and, in one case, with nasal resistance measurements. Acoustic rhinometry is a rapid, reproducible and non-invasive technique. This pilot study demonstrates that it has potential for studying in detail the physiology of the nasal cycle.
利用多种技术已在人体中证实了鼻周期，这些技术包括磁共振成像、前鼻镜检查、鼻阻力测量法，但所有这些技术都因费用、不适、范围有限或重复性差而存在局限性。声反射鼻测量法是一种新技术，它可分析整个鼻腔的鼻道形态，而不仅仅是在气流受限段。六名成年志愿者每隔15至30分钟接受一次声反射鼻测量法检查。三名受试者出现了典型的交替周期，两名受试者出现了非典型周期，一名受试者未出现周期。整个鼻腔都发生了变化，这与阻塞主观评分的波动相对应，在一个病例中还与鼻阻力测量结果相对应。声反射鼻测量法是一种快速、可重复且无创的技术。这项初步研究表明，它有潜力详细研究鼻周期的生理学。
