The relationships between thermograms and the physiological nasal conditions were inverstigated by thermography which indicates the temperature distribution of the body surface. It was cleared that the nasal thermogram indicated low temperature in subjects without nasal obstruction, on the contrary in those with nasal obstruction high temperature was indicated.
To clear such phenomenon, the naris was plugged with a cotton ball, and the nasal respiration was loaded. From the results, the temperature on thermogram was increased. This change was greater in hyperesthetic rhinitis than normal.
The nasal thermogram was rapidly creased after stimulation to hands with cold water and increased gradually until slightly over than before the stimulation and recovered in normal subjects. In hyperesthetic rhinitis, the patterns were divided into three types; unstabilized luctuation of temperature at 5-10 minutes after stimulation and followed by increased of temper ature (Type 1), no change of temperature (Type 2), decreased of temperature (Type 3).
From these results, it was cleared that the nasal thermogram was closely related with nasal obstruction, and with the autonomic nervous system which controlled the current of blood at nasal mucous membrane, because the fluctuation of nasal thermogram with stimulation of cold water and the fluctuation of the current of blood at nasal mucous membrane with same stimulation seemed identical.
Therefore, the techniques of nasal thermography seemed the useful method to clear the autonomic nervous system in the nasal cavity.
