Abstract
OBJECTIVE: To describe temporal trends in the incidence rate of surgically treated middle ear cholesteatoma in Danish children from 1977 to 2010.
METHODS: Data on surgically treated middle ear cholesteatoma was drawn from the Danish National Patient Register. A change in incidence rate over time was examined using Poisson regression analysis, while the cumulative incidence proportion was estimated using life-tables.
RESULTS: A total of 5850 cases of surgically treated middle ear cholesteatoma distributed among 3874 children aged 0-15 years were identified. From 1977 to 2002 the age-standardized incidence rates for first-time surgically treated middle ear cholesteatoma increased from 8 to 15 per 100,000 person-years with an estimated annual increase of 1.8% (95% confidence interval (CI) 1.3-2.2%). From 2002 to 2010 the rates decreased from 15 to 10 per 100,000 person-years with an annual decrease of 5.4% (95% CI 3.2-7.5%). Age-specific incidence rates were at maximum around the age of 9 years during the whole period. The estimated cumulative incidence proportion at age 16 years based on the 2010 age-specific incidence rates was 0.16% (95% CI 0.09-0.32%) compared with 0.20% (95% CI 0.11-0.37%) based on the 2000 age-specific incidence rates.
CONCLUSION: From 2002 to 2010 there was a decrease in the incidence rate of first-time surgically treated middle ear cholesteatoma. The decrease was preceded by a significant increase in the incidence rate of middle ear ventilation tube insertion. However, further studies are needed to find possible explanations for the decrease.
