The results of manometric study on the permeability of the Eustachian tube after a crisis has been produced by exposing 26 cases of perennial nasal atopy to the threshold-dose of the responsible allergen are reported. In 73% of the cases a reduction of the permeability (16 cases) or a stenosis (4 cases) of the ipsilateral tube were found. The importance of inquiring and specifically treating a nasal allergy in patients suffering from secretory otitis is underlined.

Rhino-rheo-manometric (R.R.M.) nasal provocation test.

The nasal provocation test--which has been considered till now too much time-consuming and troublesome for the patient--becomes rapid and simple by the use of the rhino-rheo-manometry. It is possible, by this method, to evaluate the conductance of a single nasal fossa and its reduction after allergen challenge. The results of test performed in patients suffering from extrinsic perennial nasal atopy by Dermatophagoides pt. have proved that the test becomes rapid and not troublesome by using the rhino-rheo-manometry. This method, giving a provocation threshold, may be used both in diagnosis and control of specific immunotherapy.
