We reviewed the present status of our understanding of the relationship between eustachian tube function and otitis media with effusion.The eustachian tube has essentially two physiologic functions with respect to the middle ear:ventilation in the middle ear with atmospheric pressure and clearance into the nasopharynx of secretions produced within the middle ear. Abnormality of these function has been considered the most important factor in the pathogenesis of otitis media with effusion. Several studies have reported a marked reduction in the ability to reduce applied negative pressure by swallowing, which is considered one of factor of otitis media with effusion. However, there is no conclusive evidence that abnormal clearance function is a primary factor, or a secondary effect of otitis media with effusion.
