This means acute inflammation of the middle ear.
Mostly the inflammation of the middle ear is an extension from the nose and throat via the Eustachian tube e.g. in rhinitis, sinusitis, tonsillitis and adenoiditis.
It is also common in swimmers and divers particularly if the swimming pool is infected.Injuries of the tympanic membrane and fractures of the skull involving the middle ear are causative in certain cases.
The main causative organisms are streptococci, some times staphylococci and pneumococci and rarely H.influenzae.
