Advance in the pathogenesis of otitis media with effusion induced by platelet-activating factor.

Abstract

A non-suppurative inflammatory disease of the middle ear with middle ear effusion and conductive hearing loss is called otitis media with effusion. Poor eustachian tube function, immunological factors, viral factors, and other factors are primarily involved in its pathophysiology, which has not yet been completely understood. Several researcher scholars have recently studied platelet-activating factor and they found that platelet-activating factor is closely associated to the occurrence, development, and outcome of otitis media with effusion. Platelet-activating factor is a significant element contributing to the extension of otitis media with effusion. In order to give a reference for further investigation into the mechanism and clinical management of this illness, the research status of platelet-activating factor and otitis media with effusion during the past two decades is reviewed in this study, along with the mechanisms of otitis media with effusion leading to otitis media with effusion.
