title: [Interaction between asthma and maxillary sinusitis].
abstract: We have studied atopic status and respiratory function in 69 asthmatics in relation to possible radiological changes in the sinuses. These alterations were classified under four headings: normal, mucosal thickening (greater than 3 mm), polyp or opaque films. The bronchial obstruction, evaluated by FEV1/FVC ratio was compared in the 4 groups. The reversibility of airflow obstruction by beta-2-sympathomimetics (Fenoterol) was the same with or without changes in the sinuses. The atopic trait (RAST or immediate prick tests) or non-atopic asthma was not associated with any sinus abnormalities. In conclusion, if a close association between asthma and radiological disease of the sinuses exists (60% of cases), it does not seem that chronic sinusitis worsens bronchial obstruction or reduces sensitivity to beta-2-sympathomimetics. The changes in the sinus mucosa may be induced by the same aetiologic agent (allergic or non allergic) as asthma.
