健康診断における鼻腔通気度測定

抄録

The result of rhinomanometry in 285 objects in physical examination is evaluated. We measured nasal resistance with the anterior method of rhinomanometry, observed the shape of their nasal cavities and asked the examinee the level of subjective nasal obstruction. We obtained the nasal resistance in every object in a limited time.
In many of them, the measured nasal resistance was different from that we had estimated from the shape of the nasal cavity. This suggests that it is difficult to estimate the actual nasal resistance by routine intranasal examination from the nostril. The rhinomanometry was useful to examine the shape of nasal cavity objectively in physical examination.
Our study indicated that a subject would complain of subjective nasal obstruction even when the measured nasal resistance was low when there was a greater difference in the values of nasal resistance between the two nasal cavities.
