The human ear is made up of two chambers. The inner ear and the middle ear. The middle
ear is sealed off from the outside environment by the tympanic membrane - or eardrum. In
a healthy ear, this membrane acts to protect the delicate interior of the ear from contamination.
Occasionally, however, allergy, infection, or other irritation can cause a buildup of
pus, blood and other fluids within the middle ear. In these cases, the seal created by the
eardrum acts to prevent proper drainage and can actually pose a health risk.
Symptoms can include pain - caused by the buildup of pressure - and even hearing loss.
If left untreated the buildup of fluid can damage the delicate structures located behind
the eardrum - leading to temporary or even permanent hearing loss.
A myringotomy is a simple procedure in which a small tube is inserted into the eardrum
in order to allow fluids to drain out of the middle, reducing pressure and allowing any
infection to be treated with antibiotics.
Your Procedure:
On the day of your operation, you will be asked to put on a surgical gown.
You may receive a sedative by mouth and an intravenous line may be put in.
You will then be transferred to the operating table.
The surgeon will apply an antiseptic solution to the skin on the interior of the ear canal
and will then swab the area around the eardrum with a local anesthetic.
While the anesthetic is taking effect, the surgeon will position a microscope in front
of the ear. When the operative field is numb,
the surgeon will use the microscope to help make a very small incision in the lower part
of the ear drum so that the fluid can drain harmlessly away.
In most cases, one or more drainage tubes are left in place to continue to allow fluid
to escape during healing.
Sutures are not required, as the ear drum will heal naturally. And the drainage tube
will either fall out by itself - or it will removed by the surgeon, one to three weeks
later.
