Effusion Right Ans - There is fluid in the middle ear behind the tympanic
membrane. There is no infection there is just fluid. It will not be red and
bulging
Otitis media with effusion Right Ans - OME differs from AOM in that there
are no signs of acute infection
There is an accumulation of fluid behind the tympanic membrane
The tympanic membrane appears retracted and either dull gray or yellow, and
an air-fluid level
