1. Otitis media
may be caused by an obstructed Eustachian Tube which connects the middle ear to the nasopharynx
2. A 5 year old child may also have Adenoid
Hypertrophy which may also lead to infection travelling to the middle ear via the Eustachian Tube giving rise to otitis media. The Adenoids
are a collection of lymphoid tissue (like the tonsils) situated in the nasopharynx (behind the nose) in between the openings of the Eustachian Tube.
3. Otitis media is a common problem in childhood.
