Cholesteatoma is a condition wherein there is a benign growth of skin in the middle or petrous apex.
Causes of Cholesteatoma. Cholesteatoma usually occurs as a complication following a chronic ear infection but it can be a congenital (birth defect) condition too. The Eustachian tube is responsible for conveying air from the back of the nasal passage into the middle ear, a process that equalizes ear pressure. A congenital cholesteatoma, which is rare compared to the infection triggered by Eustachian. dysfunction, may occur in the middle ear and other places, such as in the neighboring skull bones. Symptoms of Cholesteatoma. The common symptoms of cholesteatoma include: 1  Drainage from ear. 2  Dizziness. There are 2 causes of cholesteatoma: 1  Congenital cholesteatomal – this is a less common cause. 2  Usually, the abnormal growth is located at the back of the eardrum. 3  The problem is identified when the child is at 6 months to 5 years old. Definition of Cholesteatoma. Cholesteatoma is a condition wherein there is a benign growth of skin in the middle or petrous apex. This growth is considered abnormal. List of causes of Cholesteatoma. Following is a list of causes or underlying conditions (see also Misdiagnosis of underlying causes of Cholesteatoma) that could possibly cause Cholesteatoma includes: 1  Middle ear infection. Cholesteatoma: Related Medical Conditions. To research the causes of Cholesteatoma, consider researching the causes of these these diseases that may be similar, or associated with Cholesteatoma: 1  Otitis media. 2  Glue ear. 3  Upper respiratory tract infection. 4  Paracetamol. 5  Chronic otitis media. 6  Radical mastectomy. Causes of a Cholesteatoma. A cholesteatoma is most commonly caused by a poorly functioning eustachian tube—the tube that leads from the back of the nose to the middle of the ear, allowing air to flow and equalizing ear pressure. The eustachian tube may not work properly due to chronic ear infections, sinus infections, colds, or allergies. Symptoms of a Cholesteatoma. Typically, the symptoms of a cholesteatoma start out mild. They become more severe as the cyst grows larger and begins to cause problems within your ear. Initially, you may experience fluids draining from the ear accompanied by an unpleasant odor. Introduction. A cholesteatoma is an uncommon abnormal collection of skin cells inside your ear. Left untreated, it can continue to grow and damage the delicate structures deep inside your ear, such as the tiny bones and organs essential for hearing and balance.  There are 2 causes of cholesteatoma: 1  Congenital cholesteatomal – this is a less common cause. 2  Acquired-this is the more common cause which is due to the tear or retraction of the eardrum. Definition of Cholesteatoma. Cholesteatoma is a condition wherein there is a benign growth of skin in the middle or petrous apex. This growth is considered abnormal. Cholesteatoma. Cholesteatoma is a skin-lined cyst that begins at the margin of the eardrum and invades the middle ear and mastoid (arrow). This photograph shows a typical cholesteatoma that has eaten into the bone, wrapped around the incus (hearing bone), and collected layers of dead skin. Treatment. Although surgery is rarely urgent, once a cholesteatoma is found, surgical treatment is the only choice. Surgery usually involves a mastoidectomy to remove the disease from the bone, and tympanoplasty to repair the eardrum.
