Cholesteatoma is a type of abnormal skin growth that develops in the middle ear. It can lead to hearing loss, dizziness, and even facial paralysis if left untreated. There are several synonyms for cholesteatoma, including "keratoma," "cholesterosis," and "epidermoid cyst." These terms are all used to describe an abnormal growth of skin cells that can occur anywhere in the body. However, when it comes to the middle ear, the term "cholesteatoma" is the most commonly used medical terminology. While cholesteatoma is treatable with surgery, it is important to seek medical attention if you experience hearing loss or other symptoms.
