There are three pathways for
pathogens to enter the ear;
through the eustachian
(auditory) tube, from the throat
and nasopharynx
from the external ear
via blood or lymph.
Usually, bacteria are trapped in
the middle ear when a bacterial
infection in the throat and
nasopharynx causes the
eustachian tube to close.
Infection of the middle ear.
