“…We know that otolaryngology has moved towards subspecialization. DasPurkayayastha et al [22] conducted a time trend analysis in Ontario between the years 1987-2007. Their findings were that overall there had been a reduction in surgery for cholesteatoma per head of population; however, numbers had increased in the tertiary centre suggesting an overall shift in the treatment of chronic ear disease [22].…”

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.

“…A Danish study reported a decline in the incidence of surgically treated cholesteatoma from 1977 to 2007, and a Canadian study reported a decline in the population-adjusted number of mastoid procedures from 1987 to 2007; however, neither could explain this decline with certainty. 31,32 Perhaps a reason for the decreasing incidence of cholesteatoma are changes in clinical practice that have led to less severe pathology of middle ear disease, such as the introduction of conjugate pneumococcal vaccines and improving evidence to inform guidelines in middle ear disease management.…”

“…This incidence rate is comparable to the rate reported in other developed countries (Table 4). [12][13][14][15][16] The incidence rate of a particular surgical treatment is generally influenced by the prevalence of the disease it treats as well as a population's accessibility to the health care. In the case of middle ear cholesteatoma surgery in Australia, sustained improvements in the population's access to health care in line with population growth may explain the constant incidence rate of cholesteatoma surgery across the study periods.…”

Objective: To investigate the incidence of middle ear cholesteatoma surgery and assess trends in mastoidectomy procedures in Australia. Study design: Cross-sectional population-based study using data from the National Hospital Morbidity Database. Methods: Admitted care episodes containing the principal diagnosis of middle ear cholesteatoma were analyzed for two 12-month periods of 2007-2008 and 2017-2018. Surgical admissions involving mastoidectomy were identified by procedure codes. Incidence rate per 100,000 person-years were compared between study periods.Results: Of the 3855 middle ear cholesteatoma admissions, 3558 (92.3%) involved surgery, with the incidence rate for cholesteatoma surgical admissions estimated at

Time trend analysis of mastoidectomy procedures performed in Ontario, 1987–2007

Abstract: The population-adjusted number of mastoid procedures for Ontario declined from 7.1 cases per 100,000 in 1986 to 4.1 cases per 100,000 in 2006. During this time the number of both modified radical mastoidectomies and revision mastoid surgeries at UHN increased.
