Cerumen impaction refers to the buildup of layers of earwax within the ear canal to the point of blocking the canal and putting pressure on the eardrum.
Cerumen impaction develops when earwax accumulates in the inner part of the ear canal and blocks the eardrum.
Cerumen traps sand or dust particles before they reach the eardrum.
The pain is caused by the pressure of several layers of impacted earwax against the eardrum.Advertisement
In children younger than one year, cerumen impaction is sometimes discovered during a routine check-up when the doctor finds that the earwax is blocking his or her view of the eardrum.
The diagnosis of impacted cerumen is usually made by examining the ear canal and eardrum with an otoscope, an instrument with a light attached that allows the doctor to look into the canal.
Although some doctors use Water Piks to remove cerumen, most do not recommend them because the stream of water is too forceful and may damage the eardrum.

Sometimes if there is an excessive build up of wax in the ear, the doctor or nurse will remove some of it so that the eardrum can be seen more clearly.
This process can irritate an infected external ear canal and can rupture an eardrum if performed improperly or if the patient moves suddenly.
Sound waves enter the ear canal and cause the eardrum to vibrate.

Myringotomy is a surgical procedure in which a small incision is made in the eardrum (the tympanic membrane), usually in both ears.
The ear is washed, a small incision made in the eardrum, the fluid sucked out, a tube inserted, and the ear packed with cotton to control bleeding.
Water should be kept out of the ear canal until the eardrum is intact.
If the procedure is repeated, structural changes in the eardrum can occur, such as loss of tone (flaccidity), shrinkage or retraction, or hardening of a spot on the eardrum (tympanosclerosis).
It is also possible that the incision will not heal properly, leaving a permanent hole in the eardrum, which can cause some hearing loss and increases the risk of infection.
Tympanic membrane-The eardrum, a thin disc of tissue that separates the outer ear from the middle ear.

The eardrum can also become damaged by direct injury from a foreign object or sudden noise.
Rarely, a small hole may remain in the eardrum after a pressure-equalizing tube (tympanostomy tube) falls out or is removed by a doctor.
This examination makes possible the diagnosis of eardrum perforation by allowing the doctor to see an opening in the eardrum or damage to bones in the middle ear.
Treatment of a perforated eardrum is aimed at relieving pain or pressure behind the eardrum, treating any infection of the ear itself or of the upper respiratory tract, and restoring hearing.
Sometimes the doctor may lance a bulging eardrum and place a tympanostomy tube in it to relieve pain and pressure and allow the ear infection to drain before spontaneous rupture occurs.
Sometimes, a paper patch is placed over the eardrum until the membrane heals.
If the eardrum does not heal on its own, surgical repair (tympanoplasty) may be necessary to resolve the infection and restore hearing.
The ear should be kept clean and dry while the eardrum heals; it may help to insert ear plugs into the ears when showering or shampooing to block any water from getting in.
While a perforated eardrum may be uncomfortable, it usually heals on its own within two months.

When the eardrum vibrates, three tiny bones within the middle ear, called ossicles, transmit these sounds to the inner ear.
The eustachian tube, which connects the middle ear to the nose, normally equalizes pressure in the middle ear, allowing the eardrum and ossicles to vibrate correctly, so that hearing is normal.
