[Elektronische Daten] The number of operations for cholesteatoma, together with the number of cases undergoing insertion of ventilation tubes in the Tayside region of Scotland between 1966 and 1986 have been studied. During this period there has been a sixty fold increase in the use of ventilation tubes, but the incidence of cholesteatoma surgery has only varied between 0.94 and 1.88 operations per 10000 of population per year. The mean annual incidence of cholesteatoma during this period was 1.32 cases per 10 000 of population. The results indicate that there has been neither a rise nor a fall in the incidence of cholesteatoma in Tayside despite a considerable increase in the use of ventilation tubes.
