Middle ear skin developing behind the eardrum is called cholesteatoma. Regular infections and/or a tear or in drawing of the eardrum can let skin into the middle ear.
A cholesteatoma typically occurs from deranged Eustachian tube function or a middle ear infection. Once the Eustachian tubes works poorly, maybe owing to allergy, or sinusitis, the air in the middle ear is absorbed by the body, producing a vacuum in the ear.
The vacuum pressure draws the ear drum in as a pouch or sac,particularly areas weakened by earlier infections. This can develop into a cholesteatoma.
Symptoms and dangers
The ear may drain fluid with a foul stench. As the cholesteatoma pouch or sac widens, it can cause a feeling of fullness or ear pressure, along with hearing loss. Pain behind or in the ear, particularly at night, may cause major discomfort.
