What is cholesteatoma?

Cholesteatoma is a skin-containing cyst or growth located in or near the middle ear. The growth can be either present at birth (congenital) or can form later in childhood, sometimes as a complication of chronic ear infections.


  • Drainage from the ear
  • Hearing loss in one ear
  • Pain in the ear
  • Dizziness


An ear exam with a device called otoscope to look inside the ear and check for abnormalities of the ear drum is required. Specialized examination of the ear with a microscope, CT scan and hearing tests may be helpful.


The typical treatment is surgery. If untreated, cholesteatomas can lead to deafness, facial nerve paralysis and other complications affecting the brain.
