Cholesteatoma is an expanding and destructive growth of the middle ear or mastoid. Symptoms may include drainage from the ear with or without ear pain. This may be long-term in nature. Complications can include hearing loss, ringing in the ears, and infection.

Risk factors include family history of the condition, otitis media, and injury to the ear. People with cleft palate, Turner syndrome, and Down syndrome are more commonly affected. They consist of keratin and squamous epithelium. They are not a cancer. Diagnosis is based on the appearance and may be supported by medical imaging.

Treatment generally consists of surgical removal. Surgery; however, may not restore prior hearing loss. Additionally between 5% and 50% of cases recur following removal and repeat surgery may be required.

Cholesteatoma occur in about 3 per 100,000 children and 9 per 100,000 adults a year. Males are affected more often than females. The condition was first described in 1683 by Du Verney. It was named in 1838 by Johannes Müller. The term is from "chole" meaning "cholesterol", "steat" meaning "fat", and "oma" meaning "tumor"; though the lesion is not from fat tissue.
