Frequently Asked Questions >> Cholesteatoma FAQ Cholesteatoma FAQs What Is a Cholesteatoma? A cholesteatoma is a skin growth that occurs in an abnormal location, the middle ear behind the eardrum. It is usually due to repeated infection, which causes an ingrowth of the skin of the eardrum. Cholesteatomas often take the form of a cyst or pouch that sheds layers of old skin that builds up inside the ear. Over time, the cholesteatoma can increase in size and destroy the surrounding delicate bones of the middle ear. Hearing loss, dizziness, and facial muscle paralysis are rare but can result from continued cholesteatoma growth. How Does It Occur?

The Medical Consumer's Advocate This letter originally appeared in Dr. Hoffman's column on allHealth.com. Cholesteatoma The writer reports that her young son has had two operations for cholesteatoma; she states that the doctor "botched" the operation, and he is now completely deaf in the operated ear. She is seeking more information on cholesteatoma. Cholesteatoma is best defined as "skin growing in a place where skin normally does not grow." The middle ear (the cavity behind the ear drum) is the usual location for cholesteatoma, but I have heard of cholesteatomas arising within the facial sinuses and other parts of the body (usually as a result of previous penetrating trauma, such as a stab wound, which presumably forced a collection of skin cells into the sinus or body cavity.) Middle ear cholesteatoma can arise in a number of ways. For example, some people have a condition called Eustachian tube dysfunction , in which the Eustachian tubes fail to appropriately ventilate the middle ear space. If the middle ear is poorly ventilated, the air pressure behind the ear drum can become lower than the "outside" air pressure, and if this pressure difference is large and persistent, a portion of the ear drum can be "sucked inward," forming a

Background Cholesteatomas may be acquired or congenital. These are cysts enclosing keratin surrounded by a squamous epithelium. Over time, it may increase in size and destroy the surrounding delicate bones of the middle ear. Hearing loss, dizziness, and facial muscle paralysis are rare but can result from continued cholesteatoma growth. Acquired cases may arise from several pathways. Most postulate an initiating episode of otitis media leading to tympanic membrane necrosis and repair or a retraction pocket (an invagination of part of the tympanic membrane). This leads to loss of the normal control mechanisms leading to invasion of stratified squamous epithelium through the tympanic membrane and subsequent growth. These tumors are pearly white masses present in the upper and posterior part of the middle ear cleft. Congenital cholesteatoma is much less common. It is hypothesized that they arise from epidermoid cell rests formed during the development of the middle ear. These appear as a white sphere in the anterosuperior part of the tympanic membrane. Larger lesions may lead to bony erosion. Under the microscope, acquired and congenital cases are similar and resemble an epidermal inclusion cyst of the skin with a cyst lining of keratinizing stratified squamous epithelium surrounding keratinaceous debris. The squamous epithelium is characteristically thin and devoid of rete pegs. If the tumor extends into the ossicles, bony erosion and granulation tissue may be observed.

Often it occurs in people who have had repeated ear infections and eustachian tube dysfunction. This is because negative pressure in the middle ear can cause pockets of weakened areas in the eardrum to be pulled into the middle ear. If a pocket remains in the middle ear, it can become a nodule that increases in size as it sheds old layers of skin. As the cholesteatoma continues to grow, it puts pressure on the middle ear bones, facial nerve and surrounding structures. A secondary infection which speads may ensue causing erosion of the bones and surrounding tissues. Left untreated, the cholesteatoma and infection may extend down the eustacian tube, nasopharynx and into the brain cavity. Because of these factors, a cholesteatoma is considered to be a very serious condition. Symptoms may include: Drainage from the ear Fullness Hearing loss Pain in or around the ear Imbalance Facial weakness Several tests ordered by an ENT doctor aid in diagnosis including otoscopy, hearing tests, ENGs, and CAT scans. Treatment generally couples antibiotics to rid the ear of infection and surgery to remove the growth.

A cholesteatoma is a skin growth that occurs in an abnormal location, the middle ear behind the eardrum. It is usually due to repeated infection that causes an ingrowth of the skin of the eardrum. Cholesteatomas often take the form of a cyst or pouch shedding layers of old skin that build up inside the ear. Over time, the cholesteatoma can increase in size and destroy the surrounding delicate bones of the middle ear. Hearing loss, dizziness and facial muscle paralysis are rare but can result from continued cholesteatoma growth. How does cholesteatoma occur? A cholesteatoma usually occurs because of poor eustachian tube function as well as infection in the middle ear. The eustachian tube conveys air from the back of the nose into the middle ear to equalize ear pressure ("clear the ears"). 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. The vacuum pressure sucks in a pouch or sac by stretching the eardrum, especially areas weakened by previous infections. This sac often becomes a cholesteatoma. This type of cholesteatoma is most common. 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.

Acoustic Neuromas (Tumors) Cholesteatoma is defined as a cyst located in the middle ear. Cholesteatoma can be a congenital defect, but it more commonly occurs as a complication of chronic ear infections. Long-term swelling and disfunction of the eustachian tube can lead to chronic negative pressure in the middle ear. This negative pressure pulls a portion of the eardrum (tympanic membrane) inward, creating a sac or cyst. This cyst then fills with old skin cells and other debris, becoming chronically infected. The bone behind the ear is called the mastoid bone, and it connects to the middle ear. In a healthy ear, it is filled with air; however, in cholesteatoma, this area becomes filled with irritated mucous membranes and the cholesteatoma itself often grows into this bone. The cyst typically continues to expand and may even erode the mastoid bone and middle ear bones. Meningitis, dizziness, and facial muscle paralysis are rare but can result from continued cholesteatoma growth. Initially, the ear may drain, sometimes with a foul odor. As the cholesteatoma pouch or sac enlarges, it can cause a full feeling or pressure in the ear, along with hearing loss. (An ache behind or in the ear, especially at night, may cause significant discomfort.) Dizziness, or muscle weakness on one side of the face (the side of the infected ear) can also occur. Any, or all, of these symptoms are good reasons to seek medical evaluation. Cholesteatoma may be prevented by prompt treatment of ear infections.

Cholesteatoma is the name given to skin lined tumors of the middle ear and mastoid. Roughly speaking, there are two kinds of cholesteatomas: congenital and acquired. Congenital cholesteatomas are usually found in children and arise from small islands of skin trapped in the middle ear during development. This form of cholesteatoma is rare, but removal of these tumors follows the same principles used for acquired cholesteatomas. Acquired cholesteatomas are due to either a hole in the eardrum or a retracted eardrum (resulting from problems with the function of the Eustachian tube). These tumors arise from the skin that covers the eardrum. Normally, the skin of the eardrum migrates from the center of the eardrum out to the ear canal. The ear canal skin moves from the inner part of the canal towards the outer ear canal. This movement produces the self-cleaning mechanism of the ear canal. In patients who have either holes in the eardrum (tympanic membrane perforation) or Eustachian tube dysfunction, the skin of the eardrum can either migrate into the middle ear space or can accumulate within pockets of a retracted eardrum. The skin cells then accumulate and grow layer upon layer like an onion to form a cholesteatoma. As cholesteatomas grow, they can destroy the ossicles (malleus, incus and stapes), the inner ear (horizontal semicircular canal) or the facial nerve. These tumors can present with symptoms such as pain or pressure in the ear, hearing loss, dizziness, ringing sound (tinnitus), or drainage.

Cholesteatoma and Mastoidectomy What is a cholesteatoma? A cholesteatoma is a sac of skin that arises off the eardrum and erodes into the middle ear and mastoid bone. It is a benign growth or tumor that causes damage because as it grows, it erodes structures that fall in its path. What structures can a cholesteatoma effect? As the cholesteatoma grows into the middle ear it can erode the bones of hearing causing a significant hearing loss. As it grows farther it can cause a facial paralysis as it erodes into the facial nerve that supplies the muscles of the face. It may also grow into the inner ear causing spinning vertigo and inner ear or sensorineural hearing loss. If it is allowed to continue to grow it can erode into the brain cavity causing infections such as meningitis or abscess. In addition, cholesteatoma may become infected which will cause the ear to drain. Infections in the cholesteatoma cause them to grow more rapidly, thus increasing the damage that a cholesteatoma may cause. What is the treatment of cholesteatoma?

Meniere's Disease Cholesteatoma About the ears and hearing Cholesteatoma Cholesteatoma is a skin growth in the middle ear behind the eardrum. There are three causes: Repeated middle ear infections and poor eustachian tube drainage: Usually when middle ear infections become chronic, the eardrum will be sucked inward due to a vacuum that is formed in the middle ear as the fluid becomes thicker. This suction, which stretches the eardrum inward, can create a pouch or sac of skin. Eventually a skin-lined sac forms which continues to grow and cause infection and bony destruction. A perforation of the eardrum that occurs because of a chronic infection or direct trauma: The skin over the outer surface of the eardrum can grow through the perforation and into the middle ear. Cholesteatoma present at birth: This is due to skin being trapped during growth of the fetus, however, and is not very common. If you have a Cholesteatoma, you may notice drainage from your ear that has a bad smell. This is because when the dead cells accumulate in the middle ear there is no way for the body to get rid of them. As this ball of dead cells accumulates, it produces enzymes that destroy the bone. You may also feel a lot of pressure in your ear, often noted as a sense of "fullness." You may also have some hearing loss. Aching in or behind the ear, along with dizziness, or partial facial weaknesses are also signs of Cholesteatoma.
