OBJECTIVETo explore the effects of allergic factors in chronic sinusitis and nasal polyps.

METHODEosinophil in nasal secretions and allergen skin test of 1882 patients with chronic sinusitis and nasal polyps were examined before endoscopic sinus surgery. The occurrence ratios of allergic symptoms and syndromes were analyzed and compared with clinical stages of chronic sinusitis and nasal polyps.

RESULTS(1) Allergic symptoms (or syndromes) were presented in 60.4% (1137 cases) of patients in different degrees, 25.3% (477 cases) patients suffered from allergic rhinitis, 2.1% (39 cases) patients had asthma; (2) The morbidities of allergic rhinitis and asthma, the positive rates of eosinophil and allergen skin test, the occurrence rates of allergic symptoms were rising with the clinical stages in type I and type II, especially in type II stage 3; (3) There were 42.2% (795 cases) positive patients in allergen skin test, among them, 94% were sensitive to perennial allergens; (4) Allergic symptoms appeared in 26.3% (495 cases) patients, among them, 99.8% attacked perennially; (5) Of all patients, there were 38.9% (732 cases) had been operated cases before, among them 38.3% (280 cases) with allergy rhinitis. In chronic sinusitis with allergy rhinitis patients, 58.7% (477 cases) were suffered from operation.

CONCLUSIONSAllergic factors,especially perennial allergic rhinitis, are relative to clinical stages of chronic sinusitis and nasal polyps. Allergic rhinitis is an important factors in recurrence.
