Cholesteatoma is a destructive, non-cancerous growth of skin tissue that develops in the middle ear or mastoid bone, often leading to hearing loss and chronic infection. While it is most commonly referred to as a cholesteatoma, it is sometimes clinically classified based on its origin as either congenital or acquired.
The term cholesteatoma is widely used by medical professionals, though the name is technically a misnomer. The suffix "-oma" typically implies a tumor, but a cholesteatoma is not a neoplasm or a cancer; it is a keratinizing squamous epithelium growth. Historically, in older medical literature, you may encounter terms such as "pearly tumor of the middle ear" due to the glistening, white appearance of the keratin debris within the sac. Other historical or descriptive terms include "keratoma of the middle ear" or "epidermosis of the middle ear." These older terms are rarely used today, as the medical community has standardized the nomenclature for clarity in diagnostic coding.
In modern clinical practice, cholesteatoma is categorized primarily by its etiology rather than by descriptive nicknames. Major classification systems utilize the following distinctions:
The confusion surrounding the name cholesteatoma stems from 19th-century observations. Early physicians were struck by the high cholesterol content found within these growths, leading them to coin the name based on the Greek word chole (bile) and steat (fat). We now know that the cholesterol is merely a byproduct of cellular breakdown, not the cause of the growth. Because cholesteatoma is a well-established clinical entity, medical professionals prefer this name for consistency in surgical planning and patient documentation, despite the historical inaccuracy of the term.
At DiseaseMaps.org, we have seen 1,133 members share their experiences with this condition. Understanding that cholesteatoma is a persistent, non-neoplastic growth is vital for patients navigating their diagnosis. Because it can cause serious complications—including facial paralysis, vertigo, and permanent hearing loss—it is critical that patients recognize the name used by their ENT surgeon is the standard for clinical treatment.
