It is a common and potentially dangerous condition. The incidence is approximately 10 cases per 100,000 population per annum. Between 7 and 10% of people diagnosed with cholesteatoma will develop a cholesteatoma in the other ear.- CockpitComment: A 43-year-old woman presented with a 25-pound weight loss in the past year despite having a good appetite.
