Abstract

The Authors examined 55 patients divided into two groups, one of 30 vasomotor rhinopatic patients and the other of 25 normal subjects. The aim of the study was to set up an objective diagnostic rhinomanometer test through observation and evaluation of reaction brought about by physical exertion following an exertion test of 5 minutes which employed a computerized climb simulator. Nasal resistance was measure before and immediately after exertion and then at intervals of 10, 20 and 50 minutes. Our data reveal a noteworthy decrease in nasal resistance brought about by the sympathetic nervous system in normal and rhinopathic subjects. Return to pre-exertion values, however occurred difference in the two groups: in the control group nasal resistance returned to pre-exertion values slowly, while in the rhinopathic group, it decreased rapidly and a rebound effect was observed. In vasomotor rhinopathy the orthosympathetic system is overcome by the para sympathetic system with regard to nasal vascularization control and, therefore, in rhinopatic patients exertion stimulates efficacions activation of the orthosympathetic system a phenomenon which does not occur in healthy subject. On the basis of our results an intensive stimulus such as physical exertion seems to have a different effect on the two groups suggesting that the vessels of nasal mucosa do not always respond in the same way, and that in vasomotor patients there is an alternate reactivity of neural control of nasal mucosa. The rhinomanometric exercise test seems to be useful in revealing this phenomenon and to be diagnostically reliable. The method is easily reproducible, non-invasive and can be usefully applied in clinical practice associated with the normal rhinomanometric challenge test.
