👂E.N.T DISORDERS👂
👂OTITIS MEDIA👂
👂DEFINITION:-
It is an inflammation of middle ear or infection of middle ear caused by
entrance of pathogenic organisms.
👂TYPES:-
It is mainly of three types:
●Acute O.M. (Suppurative otitis media)
●Serous O.M.
●Chronic O.M.
- Acute O.M.: It is an acute infection of middle ear, usually lasting less than 6
weeks.
- Serous O.M.: It means accumulation of serous fluid in middle ear without
evidence of active infection, but fluids results from a negative pressure in the
middle ear caused by Eustachian tube obstruction.
- Chronic O.M.: It is the result of repeated episodes of acute O.M. causing
irreversible tissue pathology and persistent perforation of tympanic
membrane.
It also leads to mastoid bone infection.
👂CAUSES:-
■ Pathogenic infections:
●Bacteria (streptococcus pneumonia)
●Virus
●Upper respiratory infection, e.g., sinusitis.
●Allergic reaction
■Entrance of foreign body in ear.
■Inadequate treatment of acute otitis media.
