What is a cholesteatoma?

ANSWER

When cells clump together, they can form a cyst, a small sac that's filled with air, fluid, or something else. Sometimes, skin cells inside your ear can do this and cause a lump called a cholesteatoma.

The lump typically starts deep in your ear near your eardrum and grows toward your middle and inner ear.
