Abstract
There are many papers concerned with nerve in the nasal cavity. In 1985, Kayser reported a moderate cycle in the nasal cavity due to vasodilation and vasoconstriction.

In the nasal cavity, nasal airway resistance is easily affected not only by autonomic nerve regulation, but also by outside circumstances and psychological effects. These facts tell us, that the nasal cavity as an entrance of air, works as a sensitive barrier for human beings to regulate our autonomic nerve system. We thought, that regarding autonomic nerve regulation in the middle ear, Eustachian tube system, the tubal orifices followed a cycle similar to that of the nasal cavity. We were able to examine the validity, of these hypothesis by studying the following two clinical facts.
