[Anterior rhinomanometry and intranasal challenge tests. Technique and results in 270 cases. Usefulness for the aetiological diagnosis of vasomotor rhinitis (author's transl)].

Nasal response to a large number of stimuli is almost invariably the same, with sneezing, watery rhinorrhoea and nasal obstruction constituting the three major conventional symptoms of the so-called vasomotor (autonomic) rhinitis. These symptoms are not specific to allergic reactions but can be seen in viral infections, sudden changes in temperature, inhalation of irritant fumes or of certain smells. The aetiological diagnosis of vasomotor rhinitis therefore is sometimes very difficult but seems to be greatly facilitated by intranasal challenge tests associated with anterior rhinomanometry.
