Abstract
The purpose of this report is to analyse the results of a long-term follow up of the 222 patients operated on in the 11 years from 1965 to 1975.
Relationships among patients' age, type of operation and postoperative conditions were studied using questionnaires.
The following results were obtained:
1) The incidence of cholesteatoma has increased recently among those operated on for chronic otitis media.
2) In case of cholesteatoma, the Wullstein III type operation was mainly performed.
3) Many patients who had been operated on more than twice, were under age at the time of first operation.
4) Disappearance of otorrhoea was noted in 58.8% of those answering our questionnaires.
From these results, we concluded that the operation method must be reconsidered for cholesteatoma, especially in the case of young patients. In these patients staged operation, open method or radical operation are probably more effective than the meatotympanoplastic method.
