Eustachian tube permeability during the nasal provocation test

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.
