[kōles′tē·ətō′mə]
Etymology: Gk, chole + stear, fat, oma, tumor
a cystic mass composed of epithelial cells and cholesterol that is found in the middle ear and occurs as a congenital defect or as a serious complication of chronic otitis media. The mass may occlude the middle ear, or enzymes produced by it may destroy the adjacent bones, including the ossicles. Surgery is required to remove a cholesteatoma. See also otitis media.

Patient discussion about Cholesteatoma, middle ear.
Q. Is cholesteatoma a form of cancer? My ear Doctor diagnosed me with cholesteatoma. I am very scared. Does this mean I have cancer? Can I die from this?
A. Cholesteatomas are not a form of cancer. They are benign tumors. 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.
Cholesteatomas are not life threatening but should be treated since they can cause complications if are not treated. If not treated, 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. This exposes the covering of the brain. In extreme situations, it can lead to brain infection and other severe complications.
