It shows how the normal ear functions and sound is heard by us.
When the eustachian tube is affected due to inflammation or obstruction fluid can accumulate in the middle ear. This can happen suddenly or slowly over time.In acute cases as following a cold bacterial infection leads to the condition called ASOM or Acute suppurative Otitis media which is a painful condition requiring treatment.This often resovles well with therapy and rarely only requires more advacned treatements.In NSOM or Nonsuppurative Otitis media or Glue ear the fluid is often viscous and due to the dysfunction eustachian tube the fluid does not resorb by itslef and may require a myringotomy grommet as depicted in the animation.The purpose of this procedure is to drain the fluid and restore ventillation to the middle ear and to restore the normal hearing mechanism.
