Extractions: Click on colored text for word definitions !! Before the advent of antibiotics, mastoid surgery used to be one of the most frequent surgeries performed. Acute mastoiditis was common and the treatment is a mastoidectomy . Today, mastoid surgery is performed less often. The most common indication is to remove a cholesteatoma or a skin cyst in the ear. A cholesteatoma most commonly starts to form from a retraction pocket in the eardrum. The sequence of events begins with eustachian tube dysfunction which leads to negative pressure in the middle ear . The eardrum is sucked into the middle ear and slowly forms a pocket. The pocket enlarges and retracts deep into the ear. Skin debris gets caught, it becomes infected and slowly expands. A cholesteatoma is formed, it erodes bone and can cause hearing loss, dizziness, facial paralysis and can even erode into the brain. The picture on the right shows a large attic cholesteatoma tympanosclerosis and an ear tube in the eardrum.

Causes Cholesteatoma can be a congenital (present at birth) defect, but it more commonly occurs as a complication of chronic ear infection . Long-term inflammation and malfunction of the eustachian tube leads to chronic negative pressure in the middle ear. This pulls a portion of the eardrum (tympanic membrane) inward, creating a sac or cyst that fills with old skin cells and other debris. The cyst becomes chronically infected. The cyst typically continues to fill with debris over time and may erode the mastoid bone and the bones of the middle ear. Inspection of the ear may show a pocket or perforation (opening) in the eardrum, often with drainage. The deposit of old skin cells may be visible with an otoscope.

Extractions: The Medical Consumer's Advocate This letter originally appeared in Dr. Hoffman's column on allHealth.com. 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

Extractions: 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?

Print this page Email this page to a friend Text-only version A cholesteatoma is an abnormal skin growth behind the eardrum, normally the result of severe or repeated cases of 'glue ear' (otitis media) or other middle ear infections. The growth can increase in size, forming a skin cyst or pouch and damaging the delicate bones of the middle ear, affecting hearing and balance. Cholesteatomas are slow growing, non-malignant growths but, left untreated, they can result in serious damage to the middle and inner ear. The enzymes which are contained in cholesteatomas are activated through contact with water. If the ear is infected, these enzymes will react with the fluid to erode the bone to the inner ear, potentially causing hearing loss and, if facial nerves are also affected, paralysis. In rare and extreme cases, untreated cholesteatomas can erode the intercranial cavity, causing more serious infections such as meningitis.

Extractions: Cholesteatoma A cholesteatoma is a skin growth that occurs in an abnormal location, usually in the middle ear behind the eardrum. It is most commonly due to repeated infection, which causes an ingrowth of the skin of the eardrum. It may also be congenital (present at birth). 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 hearing bones of the middle ear (ossicles). Chronic infection and hearing loss are common side effects of the disease process. Meningitis, dizziness, and facial muscle paralysis are rare but can result from continued cholesteatoma growth. 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 forms 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. 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. However, the type of cholesteatoma associated with ear infections is most common.

Extractions: Treatment and Removal of Cholesteatomas Cholesteatoma is a serious but treatable ear condition which can only be diagnosed by medical examination. Persisting earache, ear drainage, ear pressure, hearing loss, dizziness, or facial muscle weakness signals the need for evaluation by an otolaryngologist-head and neck surgeon. Initial treatment may consist of a careful cleaning of the ear, antibiotics, and ear drops. Therapy aims to stop drainage in the ear by controlling the infection. The extent or growth characteristics of a cholesteatoma must also be evaluated. Large or complicated cholesteatomas usually require surgical treatment to protect the patient from serious complications. Hearing and balance tests, x-rays of the mastoid (the skull bone next to the ear), and CAT scans (3-D x-rays) of the mastoid may be necessary. These tests are performed to determine the hearing level remaining in the ear and the extent of destruction the cholesteatoma has caused. Surgery is performed under general anesthesia in most cases. The primary purpose of the surgery is to remove the cholesteatoma and infection and achieve an infection-free, dry ear. Hearing preservation or restoration is the second goal of surgery. In cases of severe ear destruction, reconstruction may not be possible. Facial nerve repair or procedures to control dizziness are rarely required. 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. The second operation will attempt to restore hearing and, at the same time, inspect the middle ear space and mastoid for residual cholesteatoma.

Extractions: Swimmer's Ear Cholesteatoma A perforation of the ear drum will generally heal without surgery. In some cases, however, instead of normally healing, the skin of the ear drum can grow through the hole into the middle ear. If infection is present, the skin will continue to grow into the middle ear and will become a tumor of the ear termed a cholesteatoma. Cholesteatomas are NOT a form of cancer. They are benign tumors. As they grow, they can look like an onion peel of white skin formed into a ball. Cholesteatomas can also be present without a hole in the ear drum, and without a history of ear infection. These types of cholesteatoms are called congenital cholesteatomas. They are often overlooked until they grow to a relatively large size. Cholesteatoma can destroy the bones of hearing as they grow, especially when the ear is infected. Consequently, symptoms of cholesteatoma include hearing loss and recurring discharge from the ear. Pus or unpleasant smelling fluids coming from the ear are common. A surgical microscope is necessary to make a proper inspection and cleansing of the condition, especially when there is infection. Cholesteatomas actively erode bone because they contain enzymes which are activated by moisture. In time, cholesteatomas will eventually erode the bone leading into the inner ear. This can cause nerve loss and deafness as well as severe imbalance and dizziness. The thin plate of bone that separates the roof of the ear from the brain can also be eroded by cholesteatomas.

However, MR can be a complimentary modality when intracranial extension and bony defects are observed or suspected. Additionally, MR is indicated for cases of facial nerve involvement and unexplained sensorineural hearing loss. Cholesteatomas have variable signal intensities in contrast enhanced MR. Generally, signals are isointense on T1 weighed imaging and become moderately hyperintense on lengthening of the TR. Debris usually is present. Cholesteatomas typically do not enhance with gadolinium, except rarely at the edges of the lesion. MR is useful to delineate intracranial complications including abscesses, lateral sinus thrombosis, and meningitis. These lesions may occur in the middle ear, mastoid cavity, or the petrous apex.
