The purpose of this study was to evaluate the expression of proinflammatory and immunoregulatory cytokines in chronic otitis media. The expression levels of TNF-alpha, IL-1alpha, IL-6 and IL-10 were determined by Western blot analysis of tissue samples obtained during ear surgery. The expression levels of TNF-alpha, IL-1alpha and IL-6 in cholesteatoma tissues were substantially higher compared to those determined in the granulation tissue. The highest levels of TNF-alpha, IL-1 and IL-6 proteins were observed in patients with bone destruction. There were no significant differences in the expression of IL-10 levels in cholesteatoma and normal skin, but in the granulation tissue its level was substantially higher. The level of IL-10 in cholesteatoma tissues inversely correlated with the expression of proinflammatory cytokines, the degree of bone destruction and cholesteatoma invasion. Increased expressions of TNF-alpha, IL-1alpha and IL-6 in chronic otitis media and a strong positive correlation between these cytokine levels and the degree of bone destruction indicate the destructive behavior of cholesteatoma or granulation tissue.
