Biological Mediators of Inflammation in Middle Ear Effusions

Abstract

Four biological mediators of inflammation have been found in middle ear effusions from patients with otitis media with effusion. They are chemotactic factor(s), macrophage inhibition factor(s), activated complement and prostaglandins. The potential role of these mediators has been discussed in relation to their potential for maintaining inflammation in the middle ear cleft after Eustachian tube dysfunction.
