Of these, approximately 5 million patients suffer from chronic otitis media with cholesteatoma, although the overall number of cases of chronic otitis media with cholesteatoma appears to be decreasing. The prevalence of CSOM worldwide is around 65-330 million people with complaints of watery ears, 60% of them (39-200 million) suffer from significant hearing loss. The incidence of chronic otitis media with cholesteatoma is 3 in 100,000 in children and 9.2 in 100,000 adults.]]>
