title: Distribution of eosinophils in the nose in patients with perennial rhinitis.
abstract: The traditional method of classifying perennial rhinitis into eosinophilic and non-eosinophilic is by taking a single nasal smear from one nostril. In the light of personal experience it was felt that this method of sampling may be inadequate. The present study included 20 patients with perennial rhinitis undergoing nasal surgery. Serum total IgE levels were taken and those above 40 IU/ml had allergen specific IgE measured. Nasal smears and biopsies were taken from 5 sites on each side of the nose; middle and inferior turbinates and post nasal space. The smears significantly correlated with the biopsies (rs = 0.446, P < 0.001). The distribution of eosinophils between and within nasal cavities was found to differ. Representative sampling of the nose is important for accurate eosinophil expression. The definition of an eosinophil rich and poor nose requires greater clarification as it has great clinical relevance regarding management.
