Final answer:
Middle ear effusions, also known as otitis media with effusion (OME), occur when fluid becomes trapped and accumulates in the middle ear due to blockage of the eustachian tubes. This can lead to recurring and chronic earaches, especially in young children.
Step-by-step explanation:
Middle ear effusions, also known as otitis media with effusion (OME), occur when fluid becomes trapped and accumulates in the middle ear due to blockage of the eustachian tubes. This can lead to recurring and chronic earaches, especially in young children. Factors that contribute to the higher incidence of OME in children include more upper respiratory infections, shorter and shallower eustachian tubes, and spending more time lying down. Bottle feeding while lying down also increases the risk of OME. Infections that cause fluid buildup can result in increased pressure on the eardrum and may lead to complications.
