Question

During otitis media, large amounts of fluid or pus may accumulate in the tympanic cavity; the fluid is primarily ______.

Answer 1

Answer:

Interstitial fluid

Explanation:

Otitis media is an acute infection of the middle ear. It is caused mainly by bacteria and is associated with nose and throat infections. The causative bacteria pass into the auditory tube from the nasopharynx and cause infection in the middle ear. There is a build-up of a large amount of fluid interstitial fluid in the tympanic cavity resulting in reddening and bulging of the eardrum.  

Children have almost horizontal auditory tubes that decrease drainage and therefore, are most likely to become affected. To treat the condition, a small tube is inserted into the eardrum to provide a pathway for the drainage of the fluid.
