Abstract/OtherAbstract:
BACKGROUND: The sensitivity of the human nasal cavity mucosa to touch is not well understood. The site of receptors and mode of action responsible for the sensation of the nasal airflow is a topic of controversy. Previous studies have suggested that the skin-lined nasal vestibule is more sensitive to airflow than the mucosa of the nasal cavity. A possible decline in nasal sensitivity to airflow in older subjects has not been studied. METHODS: The threshold of the mucosal sensitivity to jets of air was assessed in 76 subjects with healthy nasal cavities. A total of 141 nostrils were tested, 67 in younger patients and 74 in older patients. RESULTS: Statistically significant (p < 0.001) increases in thresholds were found for all points tested for older patients compared with the younger patients. In general, the more sensitive locations were in the nasal vestibule. The nasal cavity mucosa in the inferior meatus was slightly more sensitive than the middle meatus. CONCLUSION: We have measured the threshold to touch (air jet sensitivity) in nine places in each of 141 nasal cavities and determined that the variability and sensitivity of these measurements among people varies by age and the distance from the nostril. Older subjects were found to have a higher threshold for the sensation of airflow, and the nasal vestibule was found to be more sensitive than the rest of the nasal cavity mucosa with the inferior meatus slightly more sensitive then the middle meatus.
