Chronic otitis media describes some long-term problems with the middle ear, such as a hole (perforation) in the eardrum that does not heal or a middle ear infection (otitis media) that doesn't improve or keeps returning. The middle ear is a small bony chamber with three tiny bones – the malleus, incus and stapes – covered by the eardrum (tympanic membrane).
Non-infected chronic otitis media – There is a hole in the eardrum but no infection or fluid in the middle ear. Suppurative (filled with pus) chronic otitis media – This happens when there is a hole in the eardrum and an infection in the middle ear. Chronic otitis media with cholesteatoma – A persistent hole in the eardrum sometimes can lead to a cholesteatoma, a growth (tumor) in the middle ear made of skin cells and debris.
Problems with the middle ear, such as fluid in the middle ear, a hole in the eardrum, or injury to the small, middle ear bones, can cause hearing loss.
A person can have chronic otitis media caused by a persistent hole in the eardrum for years with no symptoms or only mild hearing loss.
The doctor will ask about a history of ear infections, treatments used, and any previous ear surgery. In some cases, the primary care doctor may refer you or your child to an otolaryngologist, a doctor who specializes in treating disorders of the ears, nose and throat. One of the best ways to prevent chronic otitis media is to have any ear infection treated promptly.
After an infection clears up, a perforated eardrum may need to be repaired to prevent another infection. Suppurative chronic otitis media usually is treated with antibiotics taken by mouth and antibiotic eardrops. When a chronic ear infection spreads beyond the middle ear to the mastoid bone (the portion of bone behind the middle ear), a serious infection called mastoiditis can occur. Call your doctor immediately if you or your child develops a cloudy or foul-smelling discharge from one or both ears or has difficulty hearing. A cholesteatoma is a benign growth of skin in an abnormal location such as the middle ear or petrous apex. A perforation of the eardrum occuring because of a chronic infection or direct trauma can lead to a cholesteatoma. Some patients are born with small remnants of skin which become entrapped within the middle ear (congenital cholesteatoma) or petrous apex (petrous apex epidermoid). Complications from untreated cholesteatoma: Erosion of the ossicles or bones behind the eardrum can lead to a conductive hearing loss. Management Options: If the the sac is relatively small and the ear can be kept without infection, and the hearing remains at an acceptable level, the keratin may be cleaned out in the office under microscopic examination at periodic intervals.
In all circumstances, surgery involves general anesthesia and the procedure can last anywhere from one hour to three hours depending on the size of the cholesteatoma and extent of infection. Surgical Outcomes: Whenever surgery is performed for cholesteatoma, there are three possible results of surgery depending on what is found during the operation. If the cholesteatoma can be removed only in pieces, there is always a chance cholesteatoma fragments left behind may regrow at a later time.
If the cholesteatoma is rather extensive and adherent to the inner ear or facial nerve, it may not be possible to remove the entire cholesteatoma and a radical mastoidectomy is performed.
Surgical Procedures: Surgery can be performed either through the ear canal or in combination with an incision behind the ear. TympanoplastyWith a cholesteatoma limited to the tympanic membrane or with a small congenital cholesteatoma or with a limited cholesteatoma forming through an eardrum perforation, the procedure can be done through the ear canal. In order to allow clear visualization of the cholesteatoma, frequently it is necessary to remove the incus bone. TympanomastoidectomyFrequently the mastoid bone located behind the ear must be explored to remove any cholesteatoma that may have spread there through the middle ear.
Risks of the surgery include taste disturbance, facial paralysis, recurrence of cholesteatoma, hearing loss and dysequilibrium.
Temporary dysequilibrium can occur from dissection of the cholesteatoma from surrounding structures such as the inner ear and stapes bone. They can destroy the bones of hearing as they grow, especially when the ear is infected or if water gets into the middle ear with other infections. A history of recurring ear infections after colds, or the entrance of water into the ear from swimming, require the ear to be examined regularly for this condition. Cholesteatomas actively erode bone because they contain enzymes which are activated by moisture.
A (CAT) CT scan is obtained by the ear surgeon to determine how much the cholesteatoma has spread in the ear. Once infection is cleared up and the ear is dry, a decision regarding surgery to remove the cholesteatoma can be made. Unless the person with cholesteatoma is extremely ill with other medical conditions, microsurgery and removal of the cholesteatoma is recommended.


DISCLAIMER: The Ear Surgery Information Center offers and maintains this web site to provide information of a general nature about the conditions requiring the services of an ear surgeon. All other information contained within this web site is © 2015 Ear Surgery Information Center. A cholesteatoma is a skin growth that occurs in an abnormal location, the middle ear behind the eardrum. A cholesteatoma usually occurs because of poor eustachian tube function as well as infection in the middle ear. Large or complicated cholesteatomas usually require surgical treatment to protect the patient from serious complications. Admission to the hospital is usually done the morning of surgery, and if the surgery is performed early in the morning, discharge may be the same day.
Cholesteatoma is a serious but treatable ear condition which can only be diagnosed by medical examination. Sound is passed from the eardrum through the middle ear bones to the inner ear, where the nerve impulses for hearing are created. In rare situations, infections in the middle ear can spread deeper inside the inner ear, causing a sensorineural hearing loss and dizziness.
The doctor also will want to know about any medications being taken to treat an ear problem, including the type, dose, and length of treatment. To confirm the diagnosis, he or she will look inside the ear with a special light called an otoscope and may take a sample of drainage fluid to be examined in a laboratory. If the otolaryngologist suspects mastoiditis or a cholesteatoma, additional tests may be needed.
Antibiotic treatment of the infection causing the chronic otitis media may be enough to stop the ear from draining.
A child with chronic Eustachian tube problems may need special tubes (tympanostomy tubes) inserted into his or her eardrums to prevent repeated ear infections by allowing air to flow normally in the middle ear. However, in some cases, the hole is left open because it can act like a tympanostomy tube to allow air to flow through the middle ear and possibly prevent more infections. Also, seek emergency care for fever, swelling, tenderness or redness behind the ear, persistent or severe ear pain, dizziness, headache, confusion, or facial weakness.

The skin over the outer surface of the eardrum can start to grow through the perforation and into the middle ear. If the cholesteatoma is small and can be removed entirely in one piece, the eardrum and the ossicles are reconstructed all in one operation. Incisions are made within the ear canal and the ear canal skin along with the eardrum are lifted to inspect the middle ear.
Inner ear trauma leading to temporary dysquilibrium from overmanipulation of the stapes bone while dissecting the cholesteatoma from the surrounding structures can occur.
The eardrum is repaired using the covering (fascia) of the chewing muscle (temporalis) as a template for tympanic membrane growth.
For this reason patients who have had a cholesteatoma surgically treated and especially those who have had a canal-wall-down procedure require close follow-up to detect early recurrence. It is usually due to repeated infection, which causes an ingrowth of the skin of the eardrum. Bone erosion can cause the infection to spread into the surrounding areas, including the inner ear and brain. As the cholesteatoma pouch or sac enlarges, it can cause a full feeling or pressure in the ear, along with hearing loss. Initial treatment may consist of a careful cleaning of the ear, antibiotics, and ear drops. The primary purpose of the surgery is to remove the cholesteatoma and infection and achieve an infection-free, dry ear.
Persisting earache, ear drainage, ear pressure, hearing loss, dizziness, or facial muscle weakness signals the need for evaluation. The middle ear is connected to the back of the nose and throat by the Eustachian tube, a narrow passage that helps to control the air flow and pressure inside the middle ear. When the middle ear is infected, fluid will drain from the ear and hearing loss can worsen. Sometimes, despite appropriate antibiotics, the infection continues, and surgery may be needed to remove the infected tissue and repair the eardrum perforation and any injury to the tiny bones in the ear. Surgery usually is necessary to correct a persistent eardrum perforation or to remove a cholesteatoma.
Normally, squamous epithelium or skin lines the entire ear canal and the outer surface of the eardrum.
It is responsible for equilibrating middle ear pressure to the pressure in the external environment.


Cholesteatomas often take the form of a cyst or pouch that sheds layers of old skin that builds up inside the ear. When the eustachian tubes work poorly perhaps due to allergy, a cold or sinusitis, the air in the middle ear is absorbed by the body, and a partial vacuum results in the ear. These tests are performed to determine the hearing level remaining in the ear and the extent of destruction the cholesteatoma has caused. In rare cases of serious infection, prolonged hospitalization for antibiotic treatment may be necessary. The middle ear can become inflamed or infected when the Eustachian tube becomes blocked, for example, when someone has a cold or allergies. Cholesteatomas can cause hearing loss and are prone to get infected, which can cause ear drainage. A chronic infection and a cholesteatoma also can cause injury to the facial nerves and facial paralysis.
The outermost layer of skin is actually composed of dead cells which are constantly being sloughed off and expelled with earwax.
This tube is normally collapsed in its resting state and when we swallow or yawn, the muscles around the tube contract and cause the tube to open allowing the influx of air into the middle ear space.
Whether the bony partition between the external ear canal and mastoid is removed or not depends on the extent of disease.
Individuals' particular facts and circumstances will determine the treatment which is most appropriate. Over time, the cholesteatoma can increase in size and destroy the surrounding delicate bones of the middle ear. The vacuum pressure sucks in a pouch or sac by stretching the eardrum, especially areas weakened by previous infections. Cholesteatomas will grow large enough to erode the middle ear structures and the mastoid bone behind the middle ear. Whether full hearing returns depends on the extent of damage and how well the ear heals after surgery. When this tube does not work appropriately, a relative negative middle ear pressure is generated and maintained. The audiologist will typically check the hearing through the air, using the eardrum, bones behind the eardrum or ossicles, inner ear and hearing, cochlear nerve and central auditory pathways.
CT scans and all other imaging techniques allow us to get a gross idea of what might be going on in the middle ear and mastoid. The eardrum, malleus and incus are removed in order to allow exposure of the inner ear and facial nerve for cleaning in the office. Hearing loss, dizziness, and facial muscle paralysis are rare but can result from continued cholesteatoma growth. Reconstruction of the middle ear is not always possible in one operation; and therefore, a second operation may be performed six to twelve months later. Follow-up office visits after surgical treatment are necessary and important, because cholesteatoma sometimes recurs. This is usually compared to the hearing obtained through the mastoid bone or bony prominence behind the ear. Occasionally the cholesteatoma may invade this nerve and it may be necessary to resect the nerve anyway.
A rare congenital form of cholesteatoma (one present at birth) can occur in the middle ear and elsewhere, such as in the nearby skull bones. The second operation will attempt to restore hearing and, at the same time, inspect the middle ear space and mastoid for residual cholesteatoma.
The latter checks the hearing attained by directly stimulating the inner ear thereby bypassing the ear canal, eardrum and ossicles. The term modified radical mastoidectomy refers to an operation where this bony partition is removed and the eardrum and ossicles are reconstructed. The problem occurs when the dead cells accumulate in the middle ear and can not be expelled. A radical mastoidectomy is an operation where this bony partition is removed and the eardrum, malleus and incus bones are permanently removed so that the inner lining of the large cholesteatoma sac can be safely cleaned in the office. Gray-colored areas may represent fluid, infection, cholesteatoma or scar from previous surgery. This operation is done when an extensive cholesteatoma is encountered or one that is adherent to the inner ear or facial nerve.
