Eosinophilia in the Ethmoid Mucosa and Its Relationship to the Severity of Inflammation in Chronic Rhinosinusitis

Abstract

Eosinophilic mucosal inflammation represents the most severe inflammatory changes of the mucosa. Twenty to forty percent of the patients with chronic rhinosinusitis had no eosinophilic inflammation of the mucosa. The CT-staging system of Lund-Mackay correlated with the extent of mucosal inflammation.
