What is a cholesteatoma?

A cholesteatoma is defined as a mass of skin cells that forms in the middle ear, often as a result of a poorly functioning eustachian tube or chronic ear infections. This condition can result in a abnormal growth of skin tissue that can cause various complications, such as the destruction of surrounding structures in the ear, including the ossicles (the tiny bones involved in hearing) and even the surrounding bone.

This answer is correct because it accurately describes the nature of a cholesteatoma, which is fundamentally a collection of skin cells that can lead to significant health issues if not treated. Understanding this helps in recognizing the importance of early diagnosis and intervention, as the condition can progressively worsen and lead to hearing loss and other complications.

Other options do not accurately capture the essence of a cholesteatoma: it is not simply an ear infection, nor is it related to increased earwax production or solely causing ear pain. While these aspects can be associated with ear health, they do not define cholesteatoma itself.
