The variations of nasal resistance, after lateral right, lateral left and supine recumbency have been studied in 20 normal subjects. These variations were in order of constant succession by rhinomanometry. In lateral right recumbency (first recumbency), the mean increase of nasal resistance in lower nasal cavity was 35%; on the contrary in the following recumbency the increase was twice as large as the first one.

Abstract

The variations of nasal resistance, after lateral right, lateral left and supine recumbency have been studied in 20 normal subjects. These variations were in order of constant succession by rhinomanometry. In lateral right recumbency (first recumbency), the mean increase of nasal resistance in lower nasal cavity was 35%; on the contrary in the following recumbency the increase was twice as large as the first one. In supine recumbency the results were abnormal. In fact, with respect to the same nasal cavity, some of our subjects showed a congestion, while some showed a decongestion. It may be concluded that utilization of postural tests, like index vasomotor reactivity, must keep the increase of nasal resistance in normal subject, following postural variations in mind, in order to express a judgement of significative pathological difference.
