Cholesteatoma arises from a chronic ear infection. They are cysts located behind the eardrum that, when they grow, can damage the bones of the middle ear.
An otorhinolaryngologist is a doctor who specializes in the management and treatment of diseases of the ear, nose, throat and related structures of the head and neck.
Remember that for the proper selection of health professional that treats cholesteatoma you must consider the nature, severity and symptoms you are presenting.
