title: Cholesteatoma: a disease of the poor (socially deprived)?
abstract: Cholesteatoma is a condition describing the accumulation of squamous epithelium and keratinocytes within the middle ear space. There is conflicting evidence regarding the influence of socioeconomical status on the prevalence of cholesteatoma. Hospital episode statistics (HES) data detailing the numbers of cholesteatoma surgeries performed per area were compared with the Index of Multiple Deprivation 2010 (IMD 2010) data that give a statistical measure of deprivation per local health authority in the UK. Statistical analysis of this data was performed to identify correlations between prevalence of cholesteatoma and deprivation. A trend was identified showing that health authorities associated with an overall low IMD 2010 value indicating more deprived, had higher numbers of mastoid operations. Our results have found that increasing levels of deprivation are associated with greater numbers of mastoid operations and thus greater numbers of cholesteatomas. Our work suggests that there is a need for additional input in deprived areas to accommodate the increased numbers of mastoid operations and chronic middle ear disease.
