A cyst in the middle ear.
A cholesteatoma is a rare cyst in the middle ear. This cyst can happen because of a tear in the thin tissue between the ear canal and the middle ear, also known as a ruptured eardrum. The tear allows skin cells to enter the middle ear and make a cyst.
The cyst can become infected and damage bones in the middle ear. Damaged bones can affect hearing.
Antibiotic eardrops might help. Surgery is often needed.
