目的：为了了解鼻峰值吸气流速和主观嗅觉是否与嗅觉thresholds.Study设计和设置有任何相关性：一个队列研究的186名正常志愿者之间的工作人员和游客在大学医院招募。检测每名受试者的嗅觉阈值（103名使用桉树脑，83名使用苯乙醇），沿着使用鼻峰吸气流量（PIFR）。主观嗅觉。沿着鼻部症状、情绪和警觉性，记录了视觉模拟评分.结果：嗅觉的主观感觉与嗅觉阈值检测无相关性（P = 0.4057），其他主观测量也无相关性。有一个显着的关系，PIFR阈值测试与苯乙醇组（P = 0.002）。结论：与鼻腔通畅的感觉，自我评估的主题的嗅觉与他们的实际嗅觉能力的相关性差。意义：病人的病史不能依赖于确定他们的嗅觉能力和正式的测试时，应进行。循证医学评级：A-1b（c）2006年美国耳鼻咽喉头颈外科基金会学会。All rights reserved.
OBJECTIVE: To see if nasal peak inspiratory flow rate and subjective sense of smell had any correlation with olfactory thresholds.STUDY DESIGN AND SETTING: A cohort study of 186 normal Volunteers was recruited from among staff and visitors at a university hospital. Olfactory thresholds were detected for each Subject (103 with eucalyptol and 83 with phenethyl alcohol,), along with nasal peak inspiratory flow (PIFR). Subjective sense of smell. along with nasal symptoms, mood, and alertness, were recorded oil visual analogue scores.RESULTS: Subjective perception of smell had no correlation with olfactory thresholds detected (P = 0.4057) and the other subjective measures also had no correlation. There was a significant relationship of PIFR to thresholds in the group tested with phenethyl alcohol (P = 0.002).CONCLUSION: As with the sensation of nasal patency, the self-assessment of a Subject's sense of smell has poor correlation with their actual olfactory ability.SIGNIFICANCE: A patient's history cannot be relied upon when determining their olfactory ability and formal testing should be performed.
