what causes it?
treatment=
oitis media(infeection)
m
foreign bodies in the external acoustic meatus
excessive pressure (e.g. during
scuba diving, although this is usually secondary to infection)
Most ruptures tend to heal spontaneously, but surgical intervention may be necessary if the tear is large. Occasionally it may be
necessary to surgically enter the middle ear through the tympanic membrane (myringotomy), e.g. to
release pus from a middle ear abscess. As the chorda tympani nerve, blood vessels and the ossicles are
associated with the upper half of the tympanic membrane, incisions are usually made posteroinferiorly
