This paper describes the effects that nasal dilators have on olfactory ability. Experimental results demonstrate that nasal dilators increase odorant identification, lower odorant threshold, and increase perceptual odorant intensity. In other experiments, magnetic resonance imaging (MRI) data demonstrates that the size of the nasal cavity especially around the region of the nasal valve is increased when nasal dilators are worn. Additionally, pneumotachograph data demonstrates that during a sniff, the peak flow, maximum flow rate, volume, and duration are all increased when nasal dilators are worn. Taken together, the increase in olfactory ability can most easily be explained by an increase in both the amount and the proportion of inspired odorant molecules that are directed to the olfactory mucosa and are, therefore, available for odorant perception.
本文描述了鼻扩张器对嗅觉能力的影响。实验结果表明，鼻扩张器可提高气味识别能力，降低气味阈值，并增强气味感知强度。在其他实验中，磁共振成像（MRI）数据表明，佩戴鼻扩张器时鼻腔大小尤其是鼻瓣膜区域周围会增大。此外，呼吸流速描记器数据表明，在吸气过程中，佩戴鼻扩张器时峰值流量、最大流速、容积和持续时间均会增加。综合来看，嗅觉能力的提高最容易通过吸入的气味分子数量和比例的增加来解释，这些分子被导向嗅觉黏膜，因此可用于气味感知。
