I chose Cholesteatoma because as a child I had chronic ear infections in both of my ears. I had to have a surgery at age 2, where a doctor inserted a tiny tube in each of my ears. They did this to prevent me from getting any more infections. This disease is mainly caused by chronic ear infections (although it can sometimes be a birth defect).Cholesteatoma is caused by eustachian tubes that are not working properly. A cyst grows in the eardrum, and if left untreated can continue to grow and break the bones in the ear. Which will cause deafness in the ear. When the cyst occurs, the person will have to have surgery to remove it. This video shows how the surgery is performed.
