In 17 cases of nasal allergy (8 cases untreated, 9 cases receiving specific hyposensitization) nasal resistance was measured by rhinomanometry (16 cases by the anterior method, one case by the oscillation method).Nasal resistance was measured before, at the end of and 60 min. after nasal provocation. During provocation resistance was also determined before and after nose, blowing if the patient complained of nasal obstruction.Serous nasal secretion due to provocation was found to be an important factor in the increased resistance and a sensation of nasal obstruction based on reactive swelling of the turbinates. In unilateral provocation (10 cases), serous nasal discharge and increased nasal resistance appeared on the opposite side. In bilateral provocation (6 cases), a significant increase in nasal resistance was recognized on the narrower side.
